My jeep is throwing a random code 27. When driving you can feel it get sluggish almost but then it goes away after a minute or two. Is this the computer correcting itself or is the problem coming and going?

I have unplugged each connector while running couldn't tell a difference at any, dont know if the fault wasn't there at the time or I just couldn't hear the engine miss (Its not so smooth when idling 200,000+ miles all original)

Does anyone know the voltages/resistances that should be there? Or has anyone else had similar problem? Im thinking maybe a short in the harness some where.


Thanks
