So im having an issue with my 2002 escalade. It started last summer but never happened once during thw winter until l this week when i started using the AC again. Basically Randomly without warning the truck will start to bog down idle at abour 3-400 rpms and then die. It usually happens at stop lights or if i leave it running and run in the gas station ect. Sometimes though it will die even driving highway speeds. When it happens i have to pull over wait a few minutes and then it starts back up again.


Anyone have any ideas? I have a 2400 mile round trip to miami a week from now and need to figure this out!!

Here are some possible ideas i have. AC is overcharged? Bad Compressor? Throttle body needs cleaning?

I would clean the throttle body and change the fuel filter

 

[jcobra99]

Ok i will do both. Any idea Why it only happens when its warm outside and the AC is on? Any other ideas anyone

 

[the cadillac man]

Likely due to the added load caused by the ac compressor
I have had it happen before with my 03

Ok sounds good ill swap out the filter and clean the throttle body tonight. If that dosent work what would be my next course of action? thanks again

The only other thing that can cause it is the fuel pump of cleaning the throttle body and replacing the fuel filter doesn't help

They deleted my other post but I said to clean throttle body & air intake. Good idea to change fuel filter I forgot 03 had them. Does it have trouble starting ? More time?

 

[jcobra99]

No troubles Starting. Fuel pump is a few months old and checked pressure at schrader valve it was good. Just picked up the filter going to clean it and see how it is on the way to work tomorrow

Did they change fuel filter aswell?

Ok so the other night when i started this thread the truck died WITHOUT the AC on so its only when the temperature is warm outside not because the AC is on. I cleaned the
throttle body and it hasent had the issue again however its been rather chilly the last few days and the issue only happens when its at least 75 degrees out. and yes the fuel filter was changed but im going to change it again just for good measure

 

[godsdiablo]

If the fuel filter is new and you think it has water in it I would take off the lines and dump it out. Probably won't do anything. Do you have a check engine light? How about the air filter did you ever change that? Most likely not the problem either. Does it happen while your on the parkway or stopped at a red light

 

[jcobra99]

Ill swap out the filter tonight but its only about 6 months old like the pump. No check engine lights at all. 80% of the time it only happens at a red light or stop sign drive through ect but sometimes it will happen on the highway
