Hi Dick, I think I'll take your advise on the compression check before I invest any more time/money into the car. If the motor is bad, I'll probably just yank it out and replace with something a little more "fun". 135HP doesn't sound too good to me. This would be such a nice highway cruiser with about 250HP or more. Nobody likes to get tailgated by kids in Hondas covered with stickers after all. Have you heard of anyone doing an engine swap into one of these cars? Keep in mind that I'm in So. California, so it will HAVE TO pass smog. (we're cool on engine swaps as long as the engine is newer than the car, and 100% of the smog for the engine follows into the car, including diagnostics). I'll check, and probably change the oil tonight. At the very least I would guess that the cylinders are getting "washed" with gas at this point. You're right on when you said I'm getting too much fuel. That's why checking the pumps/filters hasn't been a priority for me. I'll check all the connections, take them apart, clean them with electronic parts cleaner, apply a little dielectric grease and re-connect checking continuity on the pins. I don't mind doing this type of work, as long as I only have to do it once (do it right the first time). Thanks again for the info, I may check a lot of this tonight and report my findings in the morning.
