are you throwing a code?

Make sure you check your plugs, wires, distributor cap, and your rotor. Mine is actin up a little but not at idle, so I'm currently checkin all that shit too.

i just put new plugs and wires in about week and a half ago and it was running fine. i took the intake manifold off to put on a high flow and that is when it started so i took it off and put my stock one back on and it still does it. i thought it was the pcv but i put a new one on and didnt change anything. its not throwing any codes though. and i checked all my vacuum lines. its getting fustrating........i just want to drive my car!!! im leaving for a week in the morning so hopefully while i am gone people will come up with some good ideas. thanks alot guys. -peacekeeper-

First off, did you disconnect your battery before you started unpluging sensors? Second, did your put a new IM gasket on? You probably need to reset your ECU to let it know that one you put a new intake on and let it recalibrate itself and now that you switched back its probably going nuts. I had the same problem when I was working on my Mom's car. All I was doing was changing plugs but I had to take the upper intake plenum to get to the back ones and when I was done it ran like crap. Why?, because I didn't bother to disconnect the battery and I forgot to hook up one measly sensor which I totally forgot about. So try that see if it works if not, I dont know.
