im guessins its a bad ecu or a bad obd1 conversion harness.timing fine. fuel pressure is fine. i got good vaccum.everything is grounded. only thing is im running greddy 310 on stock motor.i dont have stock ls injectors and my d16y8 injectors want work right in it i tried.any ideals. the motor is a b18b1 sitting in a 00 civic coupe. only mods is rods pistons and fuel pressure regulator. if that helps any

 

check O2 sensor. Also check the cat for clogs....sometimes they get clogged and they run like ****. Check that all first

 

i changed out the 02 just incase and the cat is clean

 

define "runs like ****"

 

Drop a B18C1 in there then you'll be happy.

not enough info

 

where is your fuel pressure, find some stock injectors to use and see if thats the problem. i think 310's w/o engine management is a little too much.

 

barley stays idle if i push the clutch in while moving is shut off. it bogs in every gear when i try to take it past 3100. fuel psi is sat at 38. spark plug gap is fine. i got positive feed to the injectors timing is fine. i got all the sensors plugged. no clogged fuel line. i got good vacuum.im all out of ideal besided the fact it might be a fried ecu. i might be over looking something.

 

have you put a timing light on it? and i agree that the injectors are overkill, the stock injectors could run it properly, but i don't think that is your problem.

 

310 is drowning you .

 

yup definetly need some kind of management to scale down those 310's

 

IMO, your timing is off a tooth or so, or your injectors are drowning your cylinders. I can't think of much else that would have those symptoms.

Oh yeah, great advice.

 

i want a b18c1

 

i wouldn't say my car runs and bogs...but i have a CEL for 10 and 43...being the IAT and fuel supply...if i let my car idle about 2 mins later it'll just die?? weird...it doesn't bog or anything...

i have a similar set-up being a b18b in a 98 hatch..with the conversion harness and pr4 ecu...i checked all wiring...all vaccums...all stock....everyhting is correct...but i still have my CEL...i think its your injectors..
