I just installed a Gude throttle body and a DC Sport header on my 1993 Accord EX and I now have a check engine lifgt on. Both parts were brand new and I installed them right. I went back and checked all the plugs, connectors and hoses and everything is ok. This is very annoying, I hope someone can help. If anyone has any help I would appreciate it. Thanks.

Perhap reset it first, if the CEL come back one, you gonna pull the cel and look in up.
CEL give out alot of important info.

 

then reset ecu.

 

on your passenger side kicker pan is there is a plug tape up pull it down (blue plug) and take a wire and loop it.. stick it in both holes, then turn the ignition on and your CHECK ENGINE LIGHT will blink.. fast then slow, slow fast i dont remember =... count the flashes when they switch up it's the second digit


i.e. 2 fast blinks 3 slow blinks the code is 23
2 slow blinks 3 fast blinks the code is 23

get me i just dont remember if it's fast then slow or slow then fast but you will be able to figuer it out.. once you know what CODE it is then u'll know whats the prob im sure its just something that u didnt replug or pluged wrong GL

 

how do you reset the ECU? Thanks.

 

Pull the backup fuse for ten seconds.

 

pull the "hazard" and the "ecu" fuses wait bout 60sec then put it back in. . .start up your car bout dont touch your gas or anything else... and let it run for a couple of min's then turn it off.. then on again and your out !

 

the long flash = 10, short = 1

 

reset ecu just pull the positive cable off your battery for a min.

 

A lot easier than pulling the cable off the battery.

 

Helms manual agrees with the backup fuse method. If 10 seconds doesn't work, I have heard that a few more minutes could reset it. The back-up fuse is under the hood (if you were wondering). Good luck.
