No power, difficult to get up to 45 mph.
I bought this 1995 Jeep Wrangler YJ 4 cylinder 2.5 cc with automatic transmission about two months ago, and drove it home about one hour and it was wonderful. I had no problem getting to 75 mph on the freeway. Now, I have trouble getting it up to 45 mph. It idles great, smooth running and no other apparent problem. It has trouble shifting to the next gear, unless you let off the gas, then it smoothing shifts to the next gear. I have tuned it up, plugs, wires, cap, rotor, timing is spot on, repaired a couple of vacuum leaks. Any ideas why I have no top end power/speed?
