Cold Start rough for 5s after changing fuel filter Sign In

The car I got?: 95 toyota 4runner v6 3.0

The Problem I have:

I recently changed the fuel filter and the thermostat. I changed the fuel filter because the car would sputter sometimes when I gave it gas. I changed the thermostat because it tried to overheat on me. When I changed the thermo, I went ahead and drained the anti-freeze and flushed the motor and heater core and put new in.

I had a hard time changing the filter because of the location of the filter and lost alot of gas in the process.

I started noticing pretty quickly that when the car is cold started, it will sputter for the first 5-10 seconds. When the car is still not at normal driving temp, it sometime sputters when accelerating from a complete stop.

Could I have a problem all together besides the fuel filter? I was thinking maybe there was air in the fuel line and was hoping it might work itself out. No luck.

I'm not a mechanic but I fancy myself mechanically inclined.

Thanks in advance for the help Smile

Re: Cold Start rough for 5s after changing fuel filter Sign In

Unfortunately the thermostat is the least likely cause of your overheating and the fuel filter has little to no chance of being your performance problem.

Is it overheating at low speeds in traffic or at highway speeds?

As for the running problem............. what is the condition and age of the plugs, cap, rotor and wires?

It just started right now. I hasn't tried to over heat for a while but i was just driving it and noticed the gage at about 80%.

I don't know about the plugs. I've gave the cap a visual inspection and all seems fine. Rotors, not sure. The brakes work fine. No shaky wheel when using the breaks. And I'm not sure what wire you are talking about. I don't have a short anywhere. All electrical works.

I've had this car for about 8 months and it ran like a champ.

Re: Cold Start rough for 5s after changing fuel filter Sign In

When you state is sputters, do you mean is has a misfire for a few seconds after you start it?

"Wires" would mean ignition wires. (spark plug wires)
"Rotor" would mean ignition rotor.

You say you looked at the cap. What were you looking for?

Yeah, it just sounds like it doesn't want to be running. The RPMs jump up and down and it sounds like it's going to die. That was before today. Whatever the problem is, its getting getting worse. earlier, I tried start it earlier. It started, then the RPM's went really low for a second or two before it eventually died. I restarted it, but had to keep my foot on the gas to keep it running. Eventually I didn't have to anymore, and I was able to drive it home

Im not sure where the ignition rotors/wires are. But Ill find out and check

I don't know who is deleting responses but I just wasted a whole bunch of typing because of it.

Re: Cold Start rough for 5s after changing fuel filter Sign In

There is a diagnostic port under the hood. Lift the cap and jumper TE1 to E1 and then turn the ignition on. If there are any trouble codes stored in the engine computer it will flash them using the check engine light. The codes are two digits. You can use a paper clip to jumper the terminals together. There is a terminal legend underneath the cap. Let us know what the code(s) is.

The only response I was able to get out of the test was the CEL and over drive light flashing continuously.

Re: Cold Start rough for 5s after changing fuel filter Sign In

That means there are no codes stored.

Would be interesting to see what fuel pressure is while it is running bad. You can T in a fuel pressure gauge.

Another possibility since you stated it was running hot is that you have a head gasket issue going on. The 3VZE was notorious for head gasket failures. The coolant can leak into a cylinder(s) over night and cause a misfire after start up until the coolant is burned off.

The easiest way to determine that is to take all the spark plugs out and unplug the distributor connector to disable injector and spark. Then let it sit overnight and then crank it over. If you so coolant fly out any of the spark plug holes, it is going to need head gasket work.




You don't have to add a reply markup when you post a response.

Re: Cold Start rough for 5s after changing fuel filter Sign In

Ok... I can do that overnight. I'm guessing I should, before unplugging the spark plugs, start the motor let it idle until it is idling correctly and then take spark plugs out.

Re: Cold Start rough for 5s after changing fuel filter Sign In

It really doesn't matter. You just want it to sit overnight to see if coolant gets into any of the cylinders. You should unplug the electrical connector from the distributor so it doesn't have spark of fuel when you go to crank it with the plugs out.

If coolant is leaking into any of the cylinders when it sits, you'll see coolant spray out the spark plug hole(s) when you crank the engine.

Re: Cold Start rough for 5s after changing fuel filter Sign In

I wasn't able to get to the spark plugs last night but will definitely get to them this evening.

I just wanted to real quick point out something else. I just drove the car and only let it warm up for about 2 minutes. drove it for a couple miles when I noticed that the heat temp hadn't moved. A couple seconds later the temp shot up to half way or normal driving temp. It wasn't too long after that, I had to shut the car off due to the temp getting too high.

I dont know if it means much

Re: Cold Start rough for 5s after changing fuel filter Sign In

k_bo - All: This thread is somehow
twice as wide as it should be making
it hard to read and think some info
is missing? I don't know why on that.


Refresh: This vehicle can sputter upon start up and said to
overheat too quickly suggests a head gasket problem so far.


That would be where you should be looking for evidence.


Coolant on one or more spark plugs which may dry out from running
but leave evidence on plugs up to coolant coming out of removed spark plug hole
as mentioned. That would be extreme and make conclusion of the problem
faster to blame head gasket failure.


A leak in these can leak either way of anything they seal meaning if coolant can get
out then air and or combustion gasses also go backwards into cooling system and that
vapor will confuse sensors, overheat engine quickly and run poorly as you
reported.


Suggest a cooling system pressure test with spark plugs out and marked for which
one came from which cylinder. I don't think this model year can tell you by any codes
which cylinder or if a misfire is random or just a couple but strongly suggests you can
isolate this to which ones and if not convinced more tests would prove it.


At the age and a overheat in it's history this wouldn't be that uncommon,


T

Re: Cold Start rough for 5s after changing fuel filter Sign In

The other day I randomly checked the water level in the radiator.
I couldn't see any water in it so I added some along with antifreeze,
which turned out to be very low by the way. I'd say half empty.
Or half full? I started the car and after it ran for about 5
minutes the water pump blew. Gushed out antifreeze and water
all over the ground.

That was my final straw. I Stopped trying to be a mechanic
and took it to the shop.Smile

He said after he fixed the water pump he'll go over everything find
out if there's anything else wrong. When he's done I'll be sure to
check back in with this form and let you know what was found.

Thanks again for your help. I really do appreciate it.
