No power 92
Ok I just bought a 1992 Ls400 with 195k miles on it.it didnt run when I got it it had been sitting for 3 years. It would turn over but not start so I grabbed a can of carb cleaner and sprayed it in the intake and it cranked up and sounded great! Got it home and removed the pump, cleaned it out, reinstalled it and it cranked right up!little smoke after a few minites of running though. Drove it around and it had NO power kinda like the TPS wasnt working. I decieded to do a FULL tune up on it, new timing belt, water pump, drive belt, both dist caps and rotors, wires and plugs, valve cover gaskets, fuel filter, air filter and oil change using 4 quarts 10-40, 1 quart lucus and half a can of sea foam. While I was tearing the engine apart I discovered 0 compression on cylinder 1. I put a little oil and tested it again 0 I filled it all the way up to the spark plug tube making sure the valves were closed and let it sit for 30 minites and the level never changed. I turned it over and the oil sprayed out and I tested the compression again... 0 I filled it again and let it sit over night and turned it over again the next morning and let the oil spray again my wife turned it over while I put my hand over the spark plug tube... nothing... nothing... nothing... COMPRESSION!! put the tester back on it and got 240 same as all the other cylinders!
Now the previous owner told me he stopped driving it because it would be driving find and then start slowing way down and then start driving fine again...
I am getting spark from both coils.
Oh when I test drove the car the CEL wasnt onafter I did everything and drove it around it still wasnt on but then I completely washed the bottom of the engine and I got code 25 and 26 when I started it back up again.
UPDATE: When its sitting at idle even for an hour it doesnt smoke but it I drive it 1 mile down the street beating on it it will start smoking on the drivers side. and the power comes and goes as long as your not flooring it but if you floor it no matter how fast your going it just boggs down.
