Hi guys need some help, car pissing me off. Ok car use to run fine before mod.
mods:2.5" buddy club exhaust, k&n filter,toy tuning actuator, 225lph pump, turboxs fcd, weapon R fpr set to 45psi.
Problems:
1. fuel cut, but after fooling around with the actuator it does backfire & pop often anymore on Lo, only on Hi boost.
2. car really hard to start take like 3-4 long crank be4 finally barely starts-up. so i checked and replace rotor,dis Cap,fuel filter, fuel pump, & pcv valve. , but still hard to start i had to remove the weapon R fpr, and put back the stock one, as the weapon R fpr seem like it was leaking there was fuel coming from the vacuum port sometimes
(is that how the adjustable fuel press regulator works?)
anyways now it starts with the first crank. weird. any1 know why is that??
3. now the most annoying is, for months now when i first start up the car it idles at around 1200rpm & if u press the brakes it doesnt it doesnt drop,but once warm up it idles at around 750-800rpm now if i press on the brake pedal the rpm drops to around 500rpm and keeps bouncing between the 500-800rpm sometimes at stop lights i have to keep revving as it drop so low that it almost stalls. i check vacuum lines and i dont find any leaks. so am clue-less any1 can else have this problem and how to fix???
4.also i have a glowshift boost gauge, & the needle isnt settle on a set number under vacuum bounce between 15-20hg at idle and 30hg while driving over 100km. it also spitting out some blackish water on startup.
is that right or is something wrong with my engine??? any help welcome.
