Background info:
1995 Honda Civic VX / 170,000 miles / 2nd owner, purchased from dealership in 1999. Ignition coil replaced by mechanic in July of '02. Arospeed intake installed summer of 2000, ractive exhaust installed summer of 02. Car has been in a shitload of bumps and bruises but no major [mechanical] damage.
Now for the symptoms...
I got back from being deployed to Iraq in june of '03 - my car had been running great when I left. After driving it around for a few weeks, back and forth to my parent's house [about a 5 hour highway drive] a couple of times, started to notice the tach bouncing during downshifting while slowing to a stop. Tach would bounce from about 800 up to 2000 / 3000 and then fall again - the engine would make a noise consistent with the indication too. I was puzzled but I didn't think too much of it. Then the rev bouncing started to happen while the car was at idle too...Still trying to puzzle it out. Next the check engine light came on, the indication was for a bad 02 sensor. Couldn't afford to replace it, so I just kept going...Then, one day driving back from my parent's house, the car made a *clunk* - the rpms jumped to about 5000 and the car stopped making power. No response from the gas pedal. I pulled off to the side of the highway while the rpms slowly died, and put it in neutral. When the reps got down to about 200 or so, the car stalled. In neutral. No shit. Tried to crank it again, no dice. Cut the thing off, waited a second, said some choice magic words, then tried it again. It was a little stubborn but it started and drove home the rest of the way with no problems. At some point around this time [not the same trip, but sometime that month], the tach started bouncing - and i mean BOUNCING all over the dial, from about 0 to 7000 - during acceleration - but during acceleration there IS NO corresponding bouncing rev sound from the engine. The revs and tach still bounce during deceleration, though. I've had it *clunk* and lose power a couple of other times too, and I can't draw any connections between those times to determine a cause. I pulled the ECU codes again, and now I'm no longer getting a faulty o2 sensor code. Now I'm getting a 15 and a 48. That's faulty ignition and LAF sensor.
Oh yea, water with carbon in it is blowing out of my tailpipe and the exhaust smells like it's running very rich. Doesn't burn more oil than would be expected for a 170k engine.
What the hell is wrong with my car? Anyone?
Should I even try and fix this d15? Or would it make more sense to swap?
Thanks in advance...
