My 96 (or maybe 97) Honda Civic does some strange things. They are all connected.
It will frequently refuse to start. It's not a battery/alternator issue, as it's trying to crank. It just ... refuses. It'll eventually start. Then the fun begins.
Once it's started, it'll sometimes begin revving the engine. Not that I can hear it revving, but my RPM's will jump between 0 and 8000. Sometimes it doesn't die when it hits 0 ... but if it stays there for more than a split second, it will turn off.
Sometimes it runs great. Then, out of the blue, I'll just lose the ability to accelerate. I still have electrical power, mind you. Just not any acceleration, no matter how hard/far I push down on the gas petal. I've been on a highway going 70, lose acceleration, and coasted down to 0 mph. I waited on the side of the road for a few seconds, regained acceleration, and drove until I reached work. The car never shut off.
Right now, you're thinking its a spark plug issue. And I agree... mostly. So I changed the spark plugs. The car worked great! None of these issues came back around ... for about 2-3 months. Then they began back up. So I changed the spark plugs again (and the wires). It lasted about a week before the symptoms began again. I just checked my spark plugs a few minutes ago and they all 4 look identical. There's some black on the very bottom of them, but its identical across all 4.
Any ideas? I'm flabbergasted. Thanks in advance!
