Check engine light on.99 CIVIC lx rough idle. while driving almost stalled out. had to hammer the gas to .then it took off..HELP!!!!


First get the check engine light scanned at your local parts store, they'll do it for free. I'll bet the problem is a plugged EGR passage, which is very common on those engines.

I have a 1990 Honda Civic LX, and the engine light has stayed on for 10 minutes after driving on the freeway and then it stays off for a few days. Is this something that I should be concerned about?


Maybe, your engine has electronically-controlled adjustable valves, one of the modules may be going out on you...but the only way to check that is to actually go to a Honda dealer because most indy shops do not have the equipment necessary to pinpoint which module.

I have a honda civic lx 1998 I need to know what the troubleshooting code P1399 means? The engine number is D16Y7


Get your self a EGR valve it is sticking or the EGR port is blocked i can tell you how to test it you have a volt meter but i am 100% THAT WHAT IT IS
Code P1399 is a pending misfire code.
HOW TO TEST

1. Check EGR position sensor voltage on the White/Black wire at idle - look for 1.1 - 1.2 volts with the EGR valve closed. If the EGR position sensor voltage is higher than 1.2 volts, the EGR valve is stuck open.

2. Can unplug the EGR valve and apply power to the terminal on the EGR valve that the Pink wire would normally go to and ground the terminal on the EGR valve that the Black wire would normally go to and see if the engine stalls at warm idle.

1990 Honda Civic Stall out and wont immediately restart


Disassemble and clean the carb, particularly the jets. I suspect the charge light being on is a result of your destroyed battery, which needs to be replaced. Sta-bil over the winter and a smart trickle charger will prevent the problems you are having in the future...

thank u

rate me!!

Can't take an OBD-0/pre-OBD car to auto zone as only OBD-2 cars have a hook up for the scanner.
