Alright heres the story...a week ago or so i attempted to install dsm 450cc injectors. Unfortunately, i developed a leak between the fuel rail and fuel pressure regulator. I removed the 450's and put the stockers back in...still leak. To correct this problem i installed an aem fuel rail and aem fuel pressure regulator as well as a stainless feed line between the filter and the fuel rail. After install everything was great, no more leak, but my fuel pump became really loud, much more noticeable than usual. Also, towards the rear of the car, i developed a high pitched noise (It sounds like a line is pinched or something). however, the car ran/runs great...the install was two days ago, and everything was fine yesterday. today as im driving into work, the CEL pops on and stays on. i get to work, and go for a drive during my break, the light remaining on. As im driving the light suddenly turns off. i go into wendys, start the car, light is still off, but than after about 5 mins of driving, the light turns on again. it has stayed on since (about 40mins of driving). Now, the car is not running limp or anything, it is running absolutely perfect besides the light, and noises from the fuel pump and near the tank. but peformance wise its great. no fuel smell, no nothing. what the hell could it be??? i think im going to head over to honda tomorrow and see if they can help me out.

just to let you know of my setup...
98ex
AEM CAI
Catback exhaust
AEM Fuel rail
AEW Fuel regulator
APEXI VAFC installed for about 3 months running great

TIA

i just jumped the ecu and the code is number 45. too rich/too lean...anyone have any help???

 

um... did you adjust the fuel pressure after installing the fuel rail and regulator? the regulator might be (and probably is) set to a different pressure than stock...

 

fixed! i installed a a/f gauge and tuned it (well sort of) with my afc...thanks
