having this problem right now. its hard to control the car when this happens and the mechanic can't fix it unless I can get it there so he can see/hear it. it usually dies down by the time I get there, but it returns randomly. - jessesgirl7575

Harsh start egr sticking open can't solve disfunction. I did a parsidic draw test and found out it was my comfort fuse draining my battery. Well, I started pulling it every night and everything was working good new egr valve and battery give or take 2 months car starts acting up even with fuse pulled. - Visitor

How do you replace an egr valve
rough idle at start up. runs okay on road
When putting auto in Reverse and idling out of the garage, it "jerks" and does not run smooth....
The EGR control solenoid or EGR valve may fail causing the Check Engine Light to illuminate.
