Here's a few specs on my car.. b18c1 skunk2 valvetrain, ctr pistons.. the compression is at 12.6:1.. lately now that it's been getting colder my car will stall out and also it runs rough as if about to stall out when idling.. the things i know are messed up on my car are.. TB is missing one of the springs, Fuel Filter leaks and the TPS may or may not be dead.. because my VAFC won't show the throttle %.. but I get no CEL..

Any help would be great..

Thanks in advance..

 

do you have bigger injectors, even if you don't alot of "chipped" ecu's put too much fuel at idle on cold startup , take some fuel away at idle with the vafc, like 10%

 

hrmm.. ya i don't have bigger fuel injectors.. where do i make that adjustment on my v-afc? the main thing i messed with recently is where the car idles at.. on the narrow throttle chart..
because before my car idled at 1500rpms and bounced up and down at that.. so i lowered the the idle like -30 in order to get it down to 700rpms.. but recently i upped it to like 10 because it wasn't having any probs bouncing at 1500rpms.. and it usually idles at about 700-800rpms..

i will try and mess with it tomorrow when i leave to see if it fixes it at all.. any other ideas why my motor is all mangled .. endulge me =P

thanks..

and also my ecu is the mugen ecu.. i dunno what it's fuel mixture is set at.. i really should get a damn air/fuel gauge..
