im having a really strange problem with my car. Every time i back up and turn my wheel to the right and go down a curb or a hill the engine cuts out and the car dies. Im stumped and so is my mechanic.

ive already replace the fuel pump, fuel filter, fuel pressure regulator, IAC, Mass Airflow Censor, Cam censor, broken motor mount(drivers side) and a full tune up. Really could use some advice is someone else has had this problem

 

this happens when you turn all the way to the right ?

did you check the power steering fluid ? just an idea

 

thats a good suggestion...i noticed since i put on 33's that if i turn the wheels while stopped i can actually affect the rpms....man i am stressing my baby out!!

but yeah that is a weird combo to stall...something is stressing it out.
and if it only does it at a turn and not straight back then check that pump out.

 

just a random thought. check the crank sensor wiring harness, on the passanger side bottom of timing cover. the wires hang low and could be rubbing the centerlink and pulling or shorting out worth a shot right? for giggles make sure your battery cables dont move by hand or that the lead slug isnt loose in the side of the battery. some more info would help to good luck

 

Gotta be electrical. Do an engine running 'touch test' on every harness under the hood.

 

well it turned out to be a faulty ground wire coming off the tank to the frame. thats fixed and working great. However, im loosing rpms and power when moving driving along. It will come off of a stop and go up in speed and rpms evenly. but when i hit a constant speed and keep it going, the rpms drop down to under 2000, even at freeway speeds. It seems way to under powered, suggestions?

 

cat plugged?

 

no the cat is working great i had it checked. you think maybe the tps, or egr?

 

got a light on? code? i would be thinking mass air flow sensor but could be alota things, u can unplud it and will run better if thats the problem, will hesitate a little unplugged. try and tell us more detail
