I have a 91 crx si. I just bought the car. I have tanabi exhaust, headers, and aem intake. After i drive the car for a little while the check engine light pops on. What could it be. I can't figure out why it would wait so long to come on. The car is running fine temp wise and everything. I was wondering if maybe it had something to do with the O2 senser cuz the ecu doens't like that much air but then again that may just be hopeful thinking.

Thanks for your help

 

does your speedo work? i found out last night thats why mine comes on in my 88 crx si

 

i can fix/find out why your light is coming on. i won't even charge you to check it out.

i can do your mini-me when ever you are ready too!

 

yeah you need a new instument cluster!

 

Cool thanks Chahonda. I will be giving you a call sometime. And yes my speedo does work

 

Pull the carpet out of the way on the passenger side and count the blinks......how many are there???

 

When did you get this car trey? Nice.

 

I got it about a week ago. Thanks

 

Hey slowcrx what do you mean by the blinks.

 

the ecu has an LED light that blinks on and off and depending on the number of blinks......that is the engine code that you are throwing and then we can tell you where to start looking for the problem.
