big88lx

Hey y'all. I'm hoping someone can help me. I have a 88 lx I just bought, its smoking blue smoke no oil smell more of sunburnt fuel. Puller plugs and they were soaked with gas. Found there is no o2 sensor in headers. Went to buy one and can't find one that the electrical plug fits. Its a 2 wire. The car was from factory a 4 cylinder.

So it was a 4 cyl and was replaced with a v8?? carb or efi.
My first thoughts are not o2 sensors more fp regulator or some stuck open injectors if its efi and sat for a long time . need more info on the setup here. if it is carb its probly needing rebuilt and cleaned .

well if it was my car that was smoking blue i would probably want to tear into the top end. that blue smoke is telling you something and if you didnt build the car i would feel more comfortable knowing my internals, gaskets and so on where going to be ok.

It probably washed the cyliner walls. You could try an 02 sensor made for the car instead of the motor or a universal. Might be better off to look into changing the harness. It should be a 3 wire.
