91 xj laredo bogging as if one of the wires are wrong or the cat is clogged. Both are good any ideas??

 

howdy,

sounds like MAP sensor to me. (vacuum line somewhere?)

or your TPS is going....

just a thought sir.

Could be caused by about a hundred things.

Is tuneup hardware fresh? Always start there. Fresh Champion copper plugs gapped to .035, new plug wires, cap, rotor, fuel filter.

A clogged cat or exhaust can be easily snaked out with a vacuum gauge.

Testing of your "throttle position sensor" might be a good idea here as well.

I'd start there..........

 

Thanks guys, i just replaced cap, rotor, plugs and wires, crank sensor, and a new fuel pump. Fuel filter is pretty new. Im gonna pull the plugs and check the gap, all the vaccume lines look good. Im going to order a new cat and exhaust this weekend. By any chance could the injectors cause that?
