Slow acceleration, no more that 2000 RPMS -1992 Wrangler 4.0 I6
I've been trying to troubleshoot my most recent Jeep acceleration etc. issue.
The Problem: Accelerates super slow, will barely push 2000 RPMs while in gear and but in Neutral will rev up just fine; Will not go over 40 MPH.
So Far: I've removed the exhuast/ CAT / O2 sensor that provided a little boost in acceleration in 1st and 2nd, but 3rd - 5th are still dead. I replaced the fuel filter & pump last year, and fuel delivery doesn't seem to be the issue.
Any suggestions?? This is (not) driving me crazy!! any help would be much appreciated, thank you !
