Hey everyone, I have a 93 probe GT with the 2.5L 24 valve V6. The other die it wouldn't start (dead battery) and I replaced it only to find it still wouldn't start. When I finally got it running it would sputter with any load above 1/4 throttle. It coded LHO2S and RHO2S. I replaced them an the fuel filter with no luck. I then checked compression (as to hint of proper timing). It has 175PSI on all 6 cylinders. I then separated the exhaust at the catalytic conv. And still the same. So at his point I replaced all the plugs and the crank sensor (had one laying around) and still the same. You should also know I have a new fuel pump, distributor, and plug wires. I will be checking the throttle positioning sensor today for resistance across its travel for dead spots, checking the fuel pressure, and if both check good then ill be pulling the timing belt cover to verify timing. Could anyone shed some light on what I may be missing? Your help would be greatly appreciated!
have the same problem?
