Hi guys,

I'm having problems with my engine dies after hitting large cracks/bumps in the road.

Pretty much identical to this:

Finally got a quick check engine the light...

I did the KOER & KOEO tests with the engine at normal operating temps. I got codes 137 &137 (O2 sensor rich, left & right).

I'm going to replace the sensors but I don't think it will cure my problem.

Any other ideas?

I checked all my grounds, checked for any wires that might have be rubbing.

I'm thinking I'll pick up a new ignition switch and cam sensor, seeing how they aren't too expensive

How hard is it to replace the ignition switch?


Thanks,

jay
 
Bump!! :p

I did a little reading...

I replaced my fuel pump with a 255LLPH last November after the stock one died.

I read that the fuel pump relay could also cause non-starts or the engine to stop.

I can't really remember if I could hear the fuel pump running when i tried to restart the car.

Any other ideas i just about ready to start ordering some parts!:eek:
 
Mine does it too, has somthing to do with my keys, and the ignition switch. Try making sure thats more tense than loose, if I hit a bump the key turns off electronics but the fuel pumps and the cylinders still fire.
