rough idle

Hello,

This sounds like you either have low compression is one cylinder or you have a vacuum leak.

Here is a guide to help us narrow things down a bit.

Please run some tests and get back to us.

Cheers

Thanks for the guide I ran some tests and number three cylinder only has ninety pounds compression. I guess its time to pull the heads to see what happened.
