Engine Mechanical problem
1997 Jeep YJ 4 cyl Four Wheel Drive Automatic 135000 miles

Found this jeep sitting in this guys yard, bought it for a still. Problems. Guy said it would not run, put a new battry in and an after market alarm started going off, went threw and removed all the alarm part fixed the wiring back, then just like it should it started right up and ran fine at idle. Now, if rpms go past 3000 it's like a rev limiter kicks in, tranny don't won't to shift, long story short, problems. Have changed so many sensors I can't even remember them all now, also the computer, and still have the problem! Help please.
