Thread: Odd running/ stalling issue.

Don the first thing I thought of was a loose battery. I had one in a 84 CJ7 that would jump on bumps and arc to the hood, causing similar power fluxes. Next would definately be a loose ground which would limit connectivity, making the problem exagerate with bumps, or increased power loads, like the power steering, lastly the idler thing could be a simple smog valve come loose, also had this problem on the same Jeep. It would idle way up and down at stop signs, after driving for a while on the highway. Turned out to be a disconnected 2 dollar valve. Cost about 400 in replace junk, before I found a smart mechanic!
