2003 Cadillac Escalade Sign In

Hello all!

So about a week and a half ago, it started raining. Here in Las Vegas, this is an opportunity for fun that cannot be missed. I took my 2003 Cadillac Escalade out with my girlfriend, and we found a puddle that was about 5-7 inches high and about 3 blocks long..... Like an idiot I did a U-Turn to maximize the fun.

The Caddy died in the middle of the puddle, but we got her started after about 10 minutes of just sitting there. After it started, the idle was extremely rough, and did't get better with acceleration. I let it sit there for a full day before starting it, but the same problem ensued. I took out the spark plugs, and started the engine without any water shooting out, replaced the old plugs with new spark plugs, changed the wire set, ensured all cylinders were sparking, dried out the air filter, and now changed the MAF sensor. I also put two bottles of HEET in the tank, and a few ounces of sea foam in the crankcase. The codes that are still coming up are P0171 (system too lean) and P0300 (random misfire).

The vehicle fires right up, but as soon as I put it in gear, the RPM's drop to the low 500's, high 400's. When I try to press the gas pedal down to the floor, it sounds like the "little engine that could" but there is a severe lack of power, and no gear change until I back off the pedal. The zero to 60 time is probably close to 45 seconds or so. Also, my gauge says that I'm getting 6mpg from the usual 15.5-16. The idle has gotten better right when I first start it, but thats about it.

A little background on the caddy, there is also a little leak somewhere in the caddy. Whenever I try to fill up the fuel tank all the way, it starts leaking out from under the vehicle (not where you put the fuel nozzle in). I'm wondering if there is a possibility that somehow enough water got into the tank where the HEET wouldn't even be effective, and also cause the P0171 and P0300 codes.

Any help would be greatly appreciated.

That was the most idiotic thing I ever heard of. That very well may have cost you an engine if any water got pulled into the intake.

Re: 2003 Cadillac Escalade Sign In

So my question is, what is the next step.The vehicle starts up, and is able to be put into gear. There is no arguing that it was a stupid mistake, but I'm trying to fix it.

Thanks for your help.

Fist check to see if the air filter got wet and if it did, pull all the spark plugs and do a complete compression test to find out if you bent any of the connecting rods.
Dry out everything with a blow dryer.

For future knowledge, driving through deep water can take the entire engine out to the tune of about $8K in a heartbeat.

I'm definitely going to take it to get a compression test. However, there is no abnormal engine noise at idle or at high speed. It just feels like there is no power.
