Having a problem. My engine light came on , I took it to the shop had it checked out replaced the EGR valve, mass air flow sensor, cam shaft position sensor,o2 sensor the car still feels like it going to shut off when stopped at a light. My question is should changing the plugs and wires help with the idle? I have 102,320 on the dash . Any suggestions ?

 

Need you to post the code(s) that's setting off your check engine light. Auto parts shops will usually pull it for free. Autozone, Advance, etc. Don't bother having them clear the code, that won't fix anything.
Just guessing without seeing your code, but since you've replaced the egr and other components, I'd suspect (or check next) one of the solenoids that actually trigger the EGR to open the valve is defective. If the solenoid is telling the EGR to open when it shouldn't, you'll get too much air in your fuel mix and the car will bog down or stall.
Again, get the code and post up.

 

The code that's on now is P0125 . If i'm correct that's the engine coolant sensor where is the world is that located ?

 

Info on that code:
http://www.obd-codes.com/p0125

On 4cyl engines, it's located on the opposite end of the head from the belts, left of the thermostat.
On v6, it's on the housing with the thermostat, IIRC.

From that webpage, the code doesn't mean you necessarily have to replace it.

 

Thanks for the information . I'm hoping that's all it is, the engine isn't running hot at all . Will keep you posted .
Thanks again!
