ok.. i got it... 12 short blinks.... shouldnt it have done a long blink then 2 short ones? it was 12 short ones then pause then repeated itself... where can i get ecu codes?

 

Sorry, I must be confusing my OBD levels again. Pre-OBD and OBD-0 cars will blink the number, OBD-1 and 2 cars will have the long and short blinks.

Code 12, twelve short blinks, is the EGR system. Check that out first.

 

hehe, the egr system, thats what was wrong with my hf back in the days. Just don't take it to Honda, they'll argue with you for like 30 mins that you don't have an egr

 

would this be a valve? or a sensor? anyone have nice detailed pics like that of the ecu...???? That was really helpful.. hehe...

 

Well... I'll be glad to take you a picture of the EGR vavlue, but it will be different on my STD Civic than on your HF (I think)

 

I have some nice pictures of the EGR on a '93 VX, but I don't think the CRX HF EGR system is very similar.

But yes, it is a valve that usually gets clogged with carbon when it gets old. You can clean it out with carb cleaner or just replace it. If you're lucky, the guys who put in your engine just forgot to plug it in, you could check for that while you're in there.

 

ok thanks... is that the line that runs from intake manifold to i believe the head ? is that it? ill have to do some research if not.. anyway.. thanks you guys.. once again you saved the day....

 

show your pics guys if you dont mind.. by the way if i swapped a d16z6 motor into my crx hf would i just need a different ecu? i would get the whole motor including all the parts attached like the intake mani and exhaust mani and distributer.. so would i just have needed a ecu?

 

The green is where the valve is, under the strut bar. The red highlights the extra passage in the intake manifold that runs from the valve to the four runners for the exhaust to reenter the intake charges.

This engine is currently sitting in HatchVX's garage, so I may be able to get more, better pictures. I forgot he had a strut bar in these pictures covering everything.

 

i have a problem too. i have a 91 crx hf but i just put the si 1.6 in it but it is really doggy. it doesnt run run half ass good as my friends si. i mean i know it needs a tune up but needing a tune up wouldnt make it that bad. or do u just think that its not timed good enough cuz we had to time it.
