I have a 2001 Ranger with a 2.3L, M/T, and 65,000 miles. Lately it jerks or bucks between 1500 and 2500 rpm at light throttle openings, particularly when warmed up or at ambient temps above 65 deg F. Feels like it's running lean. It runs well with the EGR unplugged (except for the MIL being lit). There is no MIL when the EGR is plugged in to indicate what's wrong. The repair shop has replaced the MAF, the fuel pump, the O2 sensor, the EGR, and the crank position sensor, without fixing the problem. What's the next thing to check? I'm guessing the problem is either with a sensor that sends info to the PCM or EGR, or the PCM itself.
have the same problem?
