When driving with a/c on max.I come to a stop,
Engine Dies, everytime, someone told me the
Engine Load Sensor might be at fault?
IF THIS TRUE, where is this sensor located?
And what does the sensor look like?
Thank-You

OK - Does it ONLY do it with A/C on or stumble some with a stop anyway?
IAC should be cleaned first and rule out any vacuum leaks. If it also stalls with use of PS like when tight parking it just can't control its idle.
Again an if - If this just had a boost or work to A/C it could be seriously overcharged or have a problem. If untouched since this began forget that for now,
T

Confirm a 99 ford escort 2.0L quick look I see only 1.8L and 1.9L.
what do you mean SMOG is no problem?
AC on max is a blend door* configuration NOT a different AC compressor setting-
Will the air flow change - vents, defroster, heater - OR fixed only out of one? Suspecting there is a vacuum leak to the applicable door* -
* HVAC doors= blend, recirculate, direction.

I found the engine - my bad I had to specify ZX2 to get 2L
Is the check engine light on?
Does it come on when starting vehicle?
I am thinking of a vacuum leak at the HVAC controller (heater controls) as it runs fine until you select MAX.
Time permitting I will get the diagram - now that I found the right vehicle-
You could attach a vacuum gauge - idle engine and observe vac readings as you select AC, then max - and other modes..

Eng.lite come on when starting, then off, I think
you hit it on the head when you said possible overcharge
But wondering is there a eng.load sensor?
If so do you know where its located?
& Whats it look like?

someone is confused - lets regroup.
When you select normal AC everything is operating no issues - correct?
When you switch to MAX AC you develop idle issues- correct?
When you select DEFROST VENT or FLOOR no idle issues- correct?
If I summarized wrong correct the description.
If correct description reread my posts #7 - ck vacuum readings
I will check back time permitting...
PS: the CEL is alot more involved than just SMOG

Some confusion: If and say IF A/C was overcharged it would choke on refrigerant in liquid state struggling to compress it BUT it really wouldn't or shouldn't be working well at all if that overcharged. Sometimes with low fan/blower for interior you are NOT evaporating the refrigerant and can even squeal a belt compressor is struggling hard and we don't know that yet.
What was JUST done to A/C? If this just began with something done to A/C it's higher on the suspect list to me anyway.
You are saying it runs fine if A/C is off - right? Does it matter whether "norm" or "max" request? It really shouldn't so for that I'm not sure just yet at all.
#1 - What was done and does this problem exactly coincide with A/C something done?

There is NO engine load sensor.
Your original post had me thinking the idle issue was only when MAX AC selected.
You now claim It stalls with AC on, with or without MAX selected?
The engine idles and does not stall with AC off?
I think an ac pressure reading HIGH and low would be a place to start, also clean the TB esp the IAC.
Tom may have an idea BUT you are not consistent or clear is description of issue. only with AC- only when MAX selected- OK with AC off - Scanning for codes,

I'm betting you are confusing engine load sensor (which doesn't exist) with the idle air control motor (which is very real).
Your IAC may be dirty or worn and unable to get your idle up with the added load of the now working AC. Take the air ducting off so you can see the intake. Open the throttle and look at the back of the blade. I bet it is looking pretty dirty. Use carb cleaner and a toothbrush and clean the hell out of it. Also remove the IAC motor and clean it and the bore it rides in. If the issue persists, replace the IAC motor.

and your time,
All my problems started, yesterday, when

Ahhhh..... Just waking up to this after the dude who wants a truck out of a car
Back some: New compressor job?? Who did what? How much oil was in old one and was just a compressor done or what on that? I TAKE IT THAT'S WHEN THIS NEW PROBLEM HAPPENED?
Charts can be wrong but just looked and you added 7.25 oz of PAG 46 somewhere? Whole system on chart I have calls for 6.75 oz WHOLE SYSTEM NOT JUST COMPRESSOR! Could be choking on oil. When a compressor crunches up (seizes) you really can't just do a compressor and some come with oil already, all should be spun with new oil prior to install and so on or will fail early up to right away.
* There's oil all thru a system so you can't know how much to add without some serious, educated guessing of what comes out of what and what went wrong or start with a full system flush and then the total. System is like an engine without a dipstick if you will and would never know if you didn't start from empty for sure.
Still get codes and clean IAC as all have suggested. Look up HAMMER TIME as the whole world sends him used tooth brushes for cleaning IAC and throttle body - oh just laugh at that for now.
Gotta know what happened here. Not funny as the compressor job may have gone all bad so check everything now that has been mentioned, get pressures read by the place that charged it if YOU did the compressor tell them exactly what you did or didn't do for this job.
Remember or learn that a compressor is just ONE part of the A/C system but can throw junk thru system. Warranties are void usually if you don't replace other components with changing those too! Gets nasty expensive to learn the hard way ----A/C is not DIY friendly at all!
You can get codes and clean that IAC and throttle body but don't use this A/C till more is known up to unplugging it now and let it go out to be checked out if all else is working that could be the whole problem?

You know, it's very possible that the AC has nothing at all to do with your problem. The AC always adds a load to the engine which the idle is supposed to compensate for and the issue is more with the idle control than the AC.

True HT - we don't know. Post #12, it died at first stop on way home from charging it up or so I read it that way. By rights it should have reacted right at the place that charged it I would think.
Was said for $75 it could be diagnosed by that shop and I suggest that. The confusion with " load sensors" for IAC - who knows yet?
I'm lost that it worked at all right away if A/C alone was totally wrong or some wild issue wasn't noticed right away not even the 12 miles it seemed to work????? Tom

If that thing came into our shop and the customer stated the engine would stall at lights with the ac on and they stated they just had the ac serviced, the first thing I would do is throw gauges on it and look at the high side. A little 4 banger isn't going to have the balls to idle right with extreme high side pressure.
Another thing is you probably screwed up just sticking a compressor on it without finding out what caused the other compressor to lock up. Restriction on the high side could have overheated the old compressor and caused it to grenade. If you didn't flush out the system, replaced the condenser, orifice tube, and accumulator, you can kiss your new compressor good bye.
Since we volunteer our time and knowledge, we ask for you to please follow up when a problem is resolved.

Right, or if someone charged it and failed to notice the fan wasn't working.

Arggh! Let's see if we can set "steven k" on his way to get out of this and understand some likely issues as I see it and even these don't cover all possible reasons for original failure and as stated problems happened instantly by his words.

***************************
There's still room for this to have nothing to do with A/C directly nor mention of other things replaced. What could have been left unplugged or who knows. Apparently the charge part of this was just farmed out and that alone? Again, they made an offer to diagnose it now and haven't heard back.
Stevenk: Please read what (none can be complete as there's just too much to know and do before touching anything never mind A/C anything as the risks for failures are so high plus worse can set you back more than the original problem!)
Some reading for you from this site to get the idea below. You can "google" your brains out and not come up with the same or be told how simple it all is and is just a rip-off biz and any handy person can do about any of it and could be more wrong.
Click to read this and this only for the A/C fix you claimed that doesn't involve any other issues still possible from info provided.
* http://autoforums.carjunky.com/...SOR_FAILURE_P116082/
[[That for a seized compressor which seems what happened to you but not why]]
* http://autoforums.carjunky.com/..._A/C_SYSTEMS_P45460/
[[That is just a charging procedure WHEN a system is expected to run properly and things done accordingly and still doesn't cover all possible things that can come up]]
I suspect you are a bit dismayed as many are. This and other things need tons of know how and equipment to succeed and sometimes things still go wrong.
This shop couldn't have known this system was ready for just a vacuum and charge unless you specifically told them OR asked them to check first which isn't in this thread.
Wish you luck and the least possible expense to get out of this. Still room for this not to really involve A/C at all and we just can't know that from the info provided.
Please do come back and say what the real problem and fix was for the sake of others if nothing else,
Tom
