So last night when I was driving home, I was shifting from 2nd to 3rd (of course in VTEC) when I released the clutch the RPM Gauge dropped all the way down to 0 and the car made a nice popping noise (coulda been a backfire), and the car was still running. So I put the clutch back in and it idled like normal. When I got up this morning, I tried to start the car and it took a second to turnover but did, and has been like that since. I have a CEL which I checked and they are a 1 and 8. Anyone know what I should look at? All the hoses are connected, timing belt is still intact, everything looks the same.

 

1 Oxygen Content

8 TDC Position

 

Code 1- Primary heated Oxygen sensor circuit low or high voltage.

Code 8- Top dead center position. No signal or intermittent interruption.
Possible causes: TDC sensor, TDC sensor circuit, ECM.

Edit- 94civicEX beat me to it.

 

I know what they are, I have the chilton manuel. I was looking for reasons for this or ways to fix it. Things I should look into.

 

The first code is your O2 Sensor on your header/exhaust manifold. It's either malfunctioned or isn't wired correctly. Have you messed with it at all doing any mods?

Code 8, it's possible that although your timing belt is intact, that the tensioner loosened and you jumped some teeth. Check the timing if you can and make sure that it isn't off. When the car is running, how does it run? TDC Sensor is in your distributor, make sure all connections to the distributor are solid. If your timing is correct and after you've reset the ECU you're still getting this code thrown, I'd probably look into replacing the distributor. If you have a friend with the same dizzy as you, borrow it and throw it on.
