Idle problems, need help!!!

[vmchurch]

So for a while now my car has been having a bad idle. I replaced the rear mount with a new one over the summer and now the idle seems to be just as bad. I originally thought it was the injectors, but after replacing those theres no change. In fact, today my car died twice before i finally decided to just start it up, gun it and try to get it to idle. The cars fine when its moving. Today was the first time that it started up and then died. What do you guys think this is? My only idea is the EGR valve. I dunno if it matters, but theres a hole in the exhaust, somewhere around the cat. Thanks for the help guys

hmm.. a rough idle is one of the hardest things to diagnose.

could be electrical. maybe your wires are going, maybe your cap/rotor are going, maybe your spark plugs are going.

could be just your throttle cable is a loose and needs to be tightened. Maybe there's a sensor thats not completley connected. injectors, but you said you already did that. fuel pump, fuel lines.

the exaust shouldnt affect it at all.

again a rough idle is the hardest thing to figure out, good luck..

yeah its killing me too. i would say go with the throte cable. maybe its not good.
do u have automatic or manual? start from here

[vmchurch]

its an auto, woudl the throttle cable cause it to have bad idle only when its not moving?

Have the Timing Checked.

maybe the throttle position sensor

Have you cleaned the IACV? Throttle Body and Plate? Changed the cap, rotor, plugs, and wires? Replaced the fuel filter?

It's also possible that your idle needs adjusting....Is it just too low? Surging?

[vmchurch]

Ok, so the plugs wires and rotor/cap are all new. The idle is where is is suppossed to be, except for when it starts to die. Not sure about the fuel filter, how do you clean the IACV and throttle body?
