I have just recently aquired a AT prelude 2.1 w/ PFI (programed feul injection) and my speed odometer won't work and once it gets warmed up my check engine light comes on after S3 starts blinking. I've replaced the speed pulsar and had to replace the timing belt SO if there is any body out there that can PLEASE help me I would be very thankful. Other than this problem I am in love with this little beast.

 

well the cel code would be a good start

 

I'm a novice (sorry ) but what is the CEL

 

CEL = Check Engine Light. You need to figure out what the CEL is telling you is the problem. Read the FAQs and look for how to read engine codes: https://honda-tech.com/zerothread/689805

 

ok so where is the code port and what do I use to read it (odb 1 or 2 tester)???

 

Well you haven't said what year your car is but the 2.1s were only in the 3rd gen preludes so that would mean you're OBD1. I don't know for sure how you check it on those models but you could read up on http://www.preludepower.com and I'm sure it won't take long to find out.

 

what year

 

mine is a 1990
