Well i have a gsr head on a itr bottom end. it has a fpr and gauge. When i try to accelerate the engine lags and the rpms go up slow. I threw CEL 45 today. I means i am running to lean or too rich. i'm assuming its lean because the engine struggles and doesn't backfire. Any ideas on how to fix this?

 

check your fuel system there might be a leak somewhere. obd-2 has all kinds of extra sensors. it might be a bad evap system, loose fuel cap. bad fuel cap, evap system doesnt hold vacumm

 

so many things. anymore input?

woot

 

does anyone know the stock fuel pressure for a b18 gsr/type r

if you have an fpr, adjust it in small incroments until it runs better. its best to dyno tune it.

 

yeah i raised the fuel pressure it 48. runs much better. the cel still turned on though. hopefully i can put it on wideband to see what is wrong.

 

it might be your o2

 

hmm my idle sometimes floats aboe the 1000 rpm range. could a vacuum leak cause this?

yeah, that could be it

 

i ran a OBDII scanner and it says i'm running lean. i turned the fuel pressure up to about 50. any suggestions?

 

?

 

CEL 45 is running to rich/lean it might be your injectors..are they pinching??

 

it says i'm running lean on a obdII scanner. what does pinching mean?

 

its when your injectors doesnt squirt as much fuel as they usually are squirting..correct me if im wrong honda-tech

 

check your dizzy timing, being retarded or too far advanced will mess with your mixture
