SOURCE: 91 camaro 305 tpi runs rough at idle sometimes

tune up-read your plugs and then check your timing. use timing light and double check with scan tool-most 91 305's were high outputs which
requires higher octane than regular (fuel grade revelatnt to compression ratio and altitude) you may want to check fuel pressure could be a clogged filter or bad pump.

Hi. I have a 99 camaro 3.8l and I'm having some


Sounds like a fuel problem,You did the coils,plug wires and sparkplugs, that should of taken care of the misfire,You may have a EGR that stay open and doesnt close properly and it doesnt set a code why the ECM compensate for the false air.Now this causes rough idle,and smooth cruise with no misfire until you get to stop or idle speed.The map sensor this can also fail when warm especially if the vacuum it is suppose to get is not met. And a failing MAP causes a lack of power. A TPS failing causes a stumble and lack of power but no misfire.cansmo_184.gif

Recurring Mystery Problem in a 1986 Suzuki Alto. (Idle related)


Bad fuel, water in the fuel, dirt in the fuel.

Drain the fuel tank completely.

Pour in a gallon or two of fresh fuel.

See how it goes.

Put some of the old fuel in a glass bottle, hold it up in front of a light and see if you can see any foreign material in it...

97 rs camaro, vibrations when idling, followed by not running


i recommend checking out your plugs and wires. If you take out any of the spark plugs look at their condition and compare them to each other if there is one darker or wetter than the others that is the one that is misfiring causing the vibration and difficulty in starting.
