Hey folks,

I just picked up a very clean dealer maintained 2000 Prelude Base with 116k KM's on it. I have since put 8k KM's on it, as well as a full 3" exhaust, PLM Tri Y and a P28 ECU basemapped by Advanced Ignition.

Prior to the mods I had noticed that it was bogging/hesitating in high rpms (~6k). Since the mod's this has seemed to switch to right about 4200-4400 RPM. I also noticed that it took a few extra seconds to start and would almost sputter a bit sometimes, and have a rough idle. This even happened on non cold starts.

Today I was driving and after about 20 minutes my CEL came on so I checked out the code and it was 43 (Fuel System). I did a bit of reading and it looks like it could really be anything with the fuel system. Based on the other symptoms does anyone have any recommendations on where to start, before replacing a bunch of things I don't need?

Thanks!

 

Put the stock ecu back in and see if the issues reoccurs.

 

I will give this a shot however it was starting to have issues prior to the p28.
