Ever since I put the vacuum guage in I'm noticing two things. Both while the jeep warms up. 1= the vacuum guage jumps all over, and 2=a slight miss... Again these both are noticed while the jeep is cold until it gets about halfway to operating temp.
Any ideas? No cel, just annoying

Lol its Ok. I'm going to do some testing before I replace them. They don't usually go bad that often I didn't think but then again for all I know they might be the originals.
