89 jeep runs crapy under 1,000 rpms!
My 89 yj wrangler with a 4.2 I6 and webber 32/34 carb run crapy under 1,000 rpms. It doesn't idle steady and never has. Wants to idle any where from 900 rpms down to 500 on somedays. It seams over the last few days it just wants to stall when your starting out in first gear. It drops way down and then pops and sputter. If I push the clucth in it will come back up to 700 or 800. If I reve it up and then let the clutch out she fine. It also does it down shifting too at time. Once your going it seems to run just fine. It has a little owder to the exhaust but no smoke. I had replaced and caped all the vacuum lines. Also rebuild the carb a few months ago when I bought the jeep. I don't want to take it to a shop just yet so any info would be great.
I want to do the nuter by pass but not sure if I'm keeping that engine in it.
