So whenever the motor on the condenser fan is completely shot I will buy a new one but for now it is fine and working. So they hit it with a hammer and it kicked right on and now it is super cold. ![]() It was getting stuck and not kicking on and that was what the sputtering was from. Apparently the motors go bad after awhile. So I had a free A/C check done on it and it was the condenser fan assembly. The A/C would get cold for a few minutes and then heat up and go back to sputtering. I added some PAG oil and this helped more. I tried adding a little freon thinking it was low since it had never been recharged in 115k miles. I also noticed it only sputtered when my A/C was on. But compressors usually last a long time. Then he said it might be the a/c compressor clutch. The mechanic used some 'Seafoam' on it and that helped a tiny bit. I have a '99 Hond a Civic LX and my car was also idling rough and 'sputtering'. But for the trouble of raising the hood, replace it while you are there! Answer If you pull the o2 sensor, sometimes they are clogged and you can clean it and put it back in. This will tell you the circuit your problems are in. You may consider buying a scanner and pulling your codes. Check all your vaccum lines too! These are all things you can check without doing anything to the motor. Your idle will be rough, then smooth out. If the engine idle changes, the problem is an intake gasket. Fill a spray bottle with water and spray all around the intake. ![]() If the diaphragm moves, it's probably good. A good way to check your EGR : start the enging, stick your finger under the EGR you should be able to feel the diaphragm. RockAuto gave the most extensive answer, sorry, but you have to start with the basic's. my problem was the spark plug wires they looked ok, but were wore out.Ĭould be coil pack, head gasket, fuel pump, or bad injector Answerspark plug fouled or coil pack bad Answer Acura integra ls 1994. In my case some of the exhaust was leaving toward the engine with a powerful force and shook the car where the engine roughly is, which lead me to think it was the engine. So check you exhaust for a funny noise that could be an interruption in the exhaust system. I found later that there was a mis-alignment(TWO PIPES WERE NOT CONNECTED) in my exhaust pipes and the flow of exhaust was interrupted. After I had replaced my spark plugs it still was rough. I put fuel system cleaners in a few times and that didn't help. When I let go it would go away for a sec then come back. Good luck AnswerCan low idle speed cause this too? AnswerMy car idled rough onced and shook horribly through the whole car when I accelerated or was just pressing the gas. Also adding a can of "Sea-foam" to your gas really couldn't hurt either. First off I would have to agree with both of the previous answers but I would also have to check out a couple more things such as the MAP censor,and the o2 censor. ![]() AnswerThere are about a million and a half things that can cause this some minor, and some quite serious. AnswerIt might just be a clogged fuel line/injector/ or pump, try to put some fuel cleaner in tank the next time you fill it up and see if that helps. Try looking under the hood in the dark with the engine running and see if you see any electrical arcing around the spark plug wires or just go ahead and replace them if they are old. A bad spark plug wire may only occasionally short out and cause these problems. Start with the easy maintenance items like spark plug wires, air filter, and fuel filter if they have not been replaced recently. It sounds like the engine might be confused about how much gas and air it is getting which might mean it needs a new oxygen sensor (EMISSION) or throttle position sensor. AnswerUnfortunately it could be a number of things causing rough idle and hesitation. If you have allowed the misfire to continue for too long, engine damage may have occurred, but otherwise correcting the cause of the misfire should set everything right. You need to do a misfire diagnosis and then correct the cause of the misfire. Nobody ever mentions an egr valve replacement.this is common in gmc vehicles.Rough idle,stalling, ignition starting trouble all relate to the egr valve sticking.
