About kenji Toelken Expertise I will do my best to answer questions regarding chassis electrical, suspension, car audio, parts fabrication, engine and drive train. I don't claim to know everything there is to know about mechanics, hopefully through this experience I can learn some stuff from all of you as well.
Experience I have been involved in auto mechanics and restoration for 30 years. I have owned and restored about 50 cars ranging from Peugeot to Hillman. I have recently built 2 CJ-5's from the ground up, fabricated parts for both and currently own a Cherokee XJ in progress.
My problem is as follows. The jeep starts fine and idles fine. In 1st gear i get to 2000 rpm's and the jeep bogs down. until I shift into 2nd gear. Then the jeep bogs down @ 2000 rpm's. Same thing happens with 3rd 4th and fifth.
It is always @ 2000 rpm's
I have done the following.
Changed plugs, wires, cap, rotor. I replaced the coil as well but same problem so took it back.
Replaced fuel filter and idle speed actuator. Jeep idles great but still the problem exists.
Any ideas on this?
Any input you would have will be greatly appreciated.
Thanks in advance,
Rob
Answer Hi Robert,
A clogged catalytic converter, improperly functioning EGR system, defective fuel pressure regulator or defective ECU (Electronic Control Unit) could all cause the symptoms you're describing. Testing equipment for this stuff isn't usually in the tool box of most do it yourselfers so you may consider having a diagnostic performed if you've got a reputable shop in your area. If you have access to the stuff I would certainly look at these things.
