I've got a '93 K1500 I bought in '20. I was after the camper that was on it and the guy said he'd give me a good deal on the truck. He said it had a new rebuilt top end and had been well taken care of. She's got 187k and I've only put about 400 miles on her.
I bought some bigger off road tires for her to grab wood in the mtns and some bigger front brakes/rotors (still need to install).
Took her out a few times in the last month and the acceleration has been boggy with some misfires/back fires.
Pulled the plugs and all the passenger side plugs are wet w/oil. Did a compression test and all the cylinders are pretty even between 170-180 and one at 150. Replaced the plugs and no change. Pulled the air filter and the TBI spray looks erratic and not like an umbrella. Tried hooking up an OBD1 and no codes.
Ordered a fuel filter,fuel pressure gauge,and distributor cap 'n plug wire for piece of mind.
Guy at Napa said likely none of the above as the passenger side plugs are wet. He'd said to check out the injectors.
Any input you guys can offer would be great. I'm getting a but in over my head, but have tools.
