could be distributor cap or rotor
I had that happen n I changed my plugs n coil pack...easy to do
If your 1997 GMC 5.7L Vortec has a misfire at an idle but not while under throttle, the problem is likely the timing. This can be adjusted.
Misfire is usually caused by faulty wires or spark plugs or both. Throttle position sensor failure generally causes poor response to the throttle. That is poor acceleration, slow to return to idle and rough idle.
Misfire is usually caused by faulty spark plug wires or spark plugs or both. I don't see the throttle body causing misfire.
its the throttle position sensor
What's wrong with my 2003 Chevy Cavalier if the check engine lights on and a friends computer said "misfire cylinder 4 "? It studders also. thanks Dawn
Throttle position sensor
have misfire on #5 on a ford f150 4.6. changed spark plug and coil pack and injector.
I have a 95, had a misfire... mine was because of the plug wires... changed the wires and plugs mis fire stopped...
Last summer, the cylindars started to misfire on my 2002 lancer. Once the spark plugs were changed, I haven't had any more issues.
yes. a valve in the open position will prevent compression, thus no combustion.
There are a couple of reasons why a 1999 Ford Contour may misfire. The spark plugs may need changed or the coil pack may be bad.
