Are our lt1's suppose to idle a bit ruff.I can feel the shake from the motor inside the car it's like a shake stop shake kind of thing.
The opti, coil, plugs and wires (both msd) have been changed.I have shortie slp headers plus the HPP tuning installed with a 160 stat. The dealer hooked it up to the tech 2 and couldn't find nothing wrong (I removed the hpp before i brought it in ).They told me it's normal for the motor to shake a bit, if it was missing wouldn't the tech 2 pick it up. By the way it's an ob1.
Any help would be welcomed.



THANKS

Do you mean rough? Ruff is a sound a dog makes.

A very slight shake is acceptable...the OBD1 cars cannot read missfires (no crank sensor) so the tech 2 can't pick that up because its not there.

 

Yup i meant rough .Thanks for the correction.
