it could be a dirty throttle plate/shaft or a bad/sticking throttle cable. also if the return spring is weak can cause this as well.

Miss fire on cylinder six on a gm sierra 1500 5.7 1996


Check compression on that cylinder. All the items you replaced could have been tested to see if they where working correctly. If they where than there was no need replace them and the next logical step would be to check for a mechanical failure rather than an electrical or engine management failure. In other words if the engine is not solid mechanically than there is no reason to replace electrical parts to try and solve the issue.

1991 Chevy Caprice has a mild miss fire and stall at low rpm: This is my latest update: I checked and cleaned the EGR,PCV,IAC valve, M.A.P sensor and Throttle body(bore/butterfly). with carb cleaner....


Do you have the idle speed turned up to keep it from dying? Because it is high. Check engine light on? Have you checked for vacuum leaks at the gasket under the throttle body? How does the car run under acceleration? You might have a worn distributor shaft.

Have you tried cleaning the throttle body. Use throttle body friendly cleaner as it has a special coating that you do not want to damage it. Clean the sutt out real good where the butterfly valve is, inside and outside.

I have a 1998 Mercury Topaz that starts to miss under acceleration and can hardly make 100k per hour. Ignition system is ok. The problem seems to be in the fuel system. New fuel filter installed and...


Even tho the ignition seems ok, I'd check the ignition cables to the plugs. Sometimes these break down over time... it will idle and drive ok, but when you need power for a hill, or acceration, that's when the wires faults start to show up.
A quick test is to put the car in drive with your left foot on the brake FIRMLY while you press the accerator... if the miss and lack of power shows up, it's usually the ignition cables to the plugs.
