94 Corsica

dew08197 · 04-05-2008, 10:09 PM

Hello everyone.

My brother has a 94 corsica and we are having a problem we can not figure out. While driving down the road the engine shakes. We have checked the mounts for trans and motor and replaced the bad ones and it is still doing it. It seems worse in warm weather and actually does not do it if it is cold. thanks let me know if u need more info

thanks

How do the spark plugs look?

We have done a complete tune up on it.

Did all the plugs look the same ? Were they "wet"?

What engine?

Good Morning dew08197, double check the actual firing order and spark leads.

Have these sparkleads been replaced ?
You can measure them but it is generally best to simply replace them.
Under power is very different to no power running.

Try some injector cleaner in the fuel tank, could be an injector sticking.

Does that vehicle have coilpacks or single coil?

Others will have different ideas.

Cheers, qldit.
