Engine Performance problem
1997 Jeep Laredo 6 cyl Two Wheel Drive Automatic 170000 miles
The engine willl idle fine till it reaches about 1500 rpms then starts skipping and popping in exhaust so far I have replaced fuel pump, injectors. Spark plugs, wires, distibutor cap, rotor button, map sensor, crank sensor, distibutor, ecm, throttle position senser and nothing has helped. Dealer checked out and says engine may need replacing due to 15 inches of vacume. Any suggestions? Also replaced oxygen sensor and catalytic converter
have the same problem?
