Civic EG

Had a p06 in my 95 dx with a 97 dx swap no check engine light so I just bought this p28 as soon as the car started up I got a check engine light some please tell me why [/list]

I would check the code (there's a stickied thread in this section on how to do that)
But I'd guess it is because you do not have a vtec motor and the P28 is a vtec ecu, so there's one code.

Also the ecu is either an auto or manual ecu and that might not match the transmission in your car. That will also throw a code.

But only way to know for sure is to check the code

Ok cool thanks man I was wondering well I got a good deal I got two for one on the ecu so ill try the other one if not ill just throw the stock one back on
