while i was on the highway i tried to acclerate the car but it was really rough... sort of bumpy... definintly not smooth.... and it only hit 8lbs of boost... then when i got off my exit... it idle'd like crap.... but it never shut off. well i got it home look in the engine bay.... no oil, and no coolant anywhere.... so i jack up the car... take out my spark plugs.... the plugs on the first rotor are black as anything.... the ones on the second rotor look white and brown and black... my friend said my coil packs were out.... and another guy said my o2 sensor was out... so i need some help... any suggestions?

 

Please list relevant mods....

A bad o2 sensor could lead to bucking/surging under cruise and light throttle but has no effect on medium to high loads.

The white coloring does NOT sound good...

 

okay...
intake
hard pipes on intake
down pipe
mid pipe
ast tank
koyo racing radiator
pined motor
street ported
2mm ceramic seals
stock ecu...
nothing other than the those that i can think of right now..

 

Do you have a boost gauge? if so what is vacuum sitting at?

Jason

 

STOCK ECU?! With those mods!? I hope you have enough for a rebuild cause guess what your prediciment sounds like? Yup, check vacuum and get compression!

 

WHY THE HELL DO PEOPLE KEEP RUNNING THESE MODS ON THE STOCK ECU!

Damn, the research was done years ago so us relatively newer owners didn't have to go through motors and some of you are ignoring it! And guess what? Boom!

rant over

Time for a compression check.

 

compression is fine checked it yesterday.... and i dont have enough money for a ecu... and yes i know the consequences of not having a ecu with the mods i have..

 

then why are you still doing it?? And whats the vacuum at?
