Ok I've been out of the honda world for a little bit, about a year, and I recently bought a 1993 honda civic ex for a daily driver, my quection is i looked at the ecu and its a pt3 which is for an accord, the car runs a little rough, but still goes, Should i switch to a p28? Any pros or cons? my other quection is I dont have a grey plug to jump for my check engine light, instead i have a blue one, but when I jump it it doestn flash the check engine light?, is this becaue of the different ecu?

 

anyone?

 

well the plug is suppose to be blue. also if the car runs with taht ecu then go with it. but i would recommend getting teh correct ecu..

 

I have read and followed this a best as posable, But now that I have installed the waterpump, both new belts I started the car and it is running rough and the only way to keep it running is to rase the rpm's it seem like its out of time or could I have something 180 Deg out, Should I remove and reset
