Sputtering and engine shake? Help Please!

Postby Tazman » Wed Dec 17, 2014 2:46 pm

I have a problem with my '95 Z26 3100. While parked I have a rough idle and the engine shakes and the exhaust bounces. When I get on the interstate from 55 -65 it will shake, but when I give it more gas it smooths out a little.
If I try to keep a constant speed it shakes like it is loosing power or something. The LIM is leaking and I had it in the shop, they found one fouled spark plug and two bad wires. They replaced the spark plug and all of the wires, but no improvement. They suspect maybe an injector. Any help would be appreciated.

I'm not sure what you want for an answer.. You have a suggestion of a possible injector... have you done any other troubleshooting? Check fuel pressure, have ICM checked at a shop, check all the coils? Is the car throwing a SES light?

Delphi for a new injector(better spray pattern). Or if you are in a bind, got a whole set just sitting around here. You would have to have them checked and tested though. Lets just say I'm not trying to make money off of them.

Thanks for the help. I plan on taking it to the shop again.
