hi!
I need help with my Honda Civic'99 Vtec VTI automatic. the check engine light goes on for a while then will go off, kinda weird coz if I start the engine with this CE light on the sound of the engine's rev is not so good (parang palyado) BUT if I wait 5 secs tops CE light will die and the Engine's rev is normal.

Engine is running fine, no notable engine noise, smooth running.

could this be loose wirings? grounded wirings?

Tnx!

does the speedometer in your car properly working?
i believe that the problem there is your knock sensor. have a mechanic check it out.

The check Engine light when goes on manifest there's an engine problem. Please bring it to the casa for sure shot trouble analysis. They have the right test equipment for it compared to ordinary mechanic.

tulad ng sabi nila dapat ma scan car mo. some emission related dtcs doesn't have noticeable effect sa drivability. bago pa lumala problema ay pa scan mo na.

your car might have a self diagnostic terminal. it is usually attached to the glove box frame on the right side. it is stuck into a light green dummy connector on the glove box frame. if you find it, jumper the two terminals with paper clip or equivalent for diagnostic request. note the blinking of the malfunction. the codes are two digit numbers. e.g. flash flash flash pause flash flash - 32. there might be more than one code, if it repeats the same code, it has finished displaying all the recorded codes.
