Rep Power: 0

After 3 weeks of patiently waiting for the Honda dealer to fix my 2002 Civic LX - I decided it was time to take matters into my own hands! Hopefully the experts on this forum can help me out??

Issue: It seems that on warm/hot days, while driving, the tach will intermittently drop to zero, and my check engine light will flash on, but then regulate itself and go back to normal. It is a super quick drop of the tach and quick loss of engine power. When/if this continues for half a dozen times within a few miles, the tach will eventually drop and stay at 0 rpms, the temp gauge will drop to cold, and the check engine light will stay on. The last time this happened it seemed like the automatic transmission locked itself in a high gear? It was slow going as I tried to accelerate from a dead stop. If I pull over, and restart the car, it will act like there was never a problem!

No codes are being shown at all, so mechanics haven't really been able to help me since it's intermittent. I have seen similar posts but I have not seen the solution.

PLEASE HELP! I need my car back!! Thanks.

no engine code but the light is on? check for loose battery terminals. if auto is locking gears, you could have a bad TPS (throttle position sensor) on the throttle body. that would explain going back to normal when restarting, and slow going acceleration. you would need a new throttle body assembly with all the sensors (or a $50 used one on ebay for auto trans).
