HKS FCON V-Pro Standalone ECU
Stage 4 BJCH Head
ARP Head Studs
780cc Injectors Ultimate Racing
272 HKS cams
Ultimate Racing Turbo-back Exhaust

HKS RS Intake
HKS SSQV BOV
Buschur Deluxe Intercooler

What could be cuasing this? When it's having the problem, and i hit the gas it does not up the rev's it just dies. And it even happens sometimes when the car's been sitting for hours. All tunning was done at buschur. Please help!

 

need a little more info. Does your car feel different (even if on occaision) when it does run? If so, please describe. Also, What was the last mod/mods done prior to this happening and how soon thereafter did it start?

 

Car always idle's very rough because of cam's, it is also tuned to run very rich. as far as last mod b4 problem, I have no idea, I just bought the car last week
