I have been looking for help but have not gotten anything solid... I just had a bad oxygen sensor replaced, new spark plugs, it is supposed to have a new distributor cap and wires on it. When I have it in gear and am stopped (stop sign/light) it idles SOOOO badly, it shudders and the oil pressure drops significantly, it just started doing this and I really wanna get it fixed. Does anyone have even the slightest idea whats going wrong?

 

Please do try to keep things into one thread...

Since a dirty EGR valve can cause poor idle quality, I would step up the time table on that sig line...

 

I'm a little new at this would you mind explaining what an EGR valve is, how to clean it, and how to replace an o2 sensor? I sure would appreciate it.

 

Please repost your question in a new thread rather than sidetrack this one.
Thanks

Almsot sounds like oyu ahve a vacuum line leaking. Make sure the hose is connected behind the intake manifold on the passengers sdie. Follow the hose and make sure its connected and not leaking.

 

Sorry for not updating this guys but last week I had the injection spider replaced and all is well! Runs great and my MPG went up big time, before I would get about 200 miles to a tank and I just refilled it at 259
