hey i have a question about my egr valve when ever i plug it in the car's idle drops too like 200 rpm's then stalls, but if i disconect it , it idles at like 6-700 and runs good?but then it doesnt pull as hard when its not conected? wat should i do...

 

i sounds like your EGR is stuck open...if the egr valve is open at idle it cause the car to idle rough and even stall. try taking the egr off and clean the port on the bottom and see if there is any carbon deposits, if that doesn't help then just replace the egr valve completely

 

Could someone post a pic of where the EGR valve is and how to get it off to try cleaning? I think I may have similar problem.
