Guest Posted December 13, 2002 Report Share Posted December 13, 2002 sheck for a vacuum leak first. spray some carb cleaner around the intake and listen for the cars idle to change (the car will try to stall). If it does, then that is where the leak is (check around the TB, where the inake meets the lower intake, etc). You can also try cleaning your IAC, and checking your spark plugs (or just go ahead and replace them, and your spark plug wires, and make sure that the gap is set correctly).

z24 turbo 93 Posted December 13, 2002 Report Share Posted December 13, 2002 Your timing can't be off in your 3.1 unless you have a aftermarket EGR valve. So do what the guy before me posted. Quote Link to comment Share on other sites More sharing options...
Guest Posted December 13, 2002 Report Share Posted December 13, 2002 Just out of curiosity, what is your mileage? Taylor Quote Link to comment Share on other sites More sharing options...
BlackSunshine Posted December 17, 2002 Report Share Posted December 17, 2002 Like Taylor said, check your gap on your sparkplugs, check your wires, and look at the elctrode on all sparkplugs to make sure they are all clean. If one or more is not than that will narrow down your search. Clean the ass out of your throttle body. Make sure you have it wide open and spray the inside, you'll be surprised at the shit that comes out. Good luck. Quote Link to comment Share on other sites More sharing options...

Redfox340 Posted February 28, 2003 Report Share Posted February 28, 2003 Piece of cake... 1.) make sure the engine is warm and at regular running tempreture 2.) next, with car off, remove intake duct to throttle body 3.) start car and use one hand for the throttle body cleaner can and the other to control the butterfly throttle plate 4.) with car running, spray the cleaner into the TB with open and closing the butterfly... "floor" the engine on several occasions while spraying 5.) shut off car after can of cleaner is emtpy 6.) re-install intake duct 7.) refire up and take a drive 8.) if SES light comes on, reset by pulling negative battery cable over-night... Pictures are available is needed... - RedFox340 Quote Link to comment Share on other sites More sharing options...
Robby1870 Posted March 1, 2003 Report Share Posted March 1, 2003 if your plugs an wires are good, your coils or ignition control module, may be bad. Do what everyone else said first, Im just giving you more options. If nothing else works, crank position sensor. Robby Quote Link to comment Share on other sites More sharing options...

Robby My '89 GS was idling poorly - just got it back from my garage along with a $600 bill - new plug wires, new ignition coil, new ignition module!! Idles like a champ now but I am even more poor Quote Link to comment Share on other sites More sharing options...
djardeli Posted March 20, 2003 Report Share Posted March 20, 2003 Does it go chug-chug-chug at regular intervals under hard acceleration in addition to the rough idle? Last time these symptoms happened to me one of my coil packs was sending out insufficient spark. my car is idling rough...it seems like it is missing maybe, or like the ignition timing is off...anyone else have a prob like this or how the hell can i fix it?
