recently after i replaced my steering rack and steering pump for rb20det on my gts, i realised da first time i kick start da car, white smoke came out. that was den.

now, every monring when i start da car, no white smoke, and check engine light. once i start drive da car, da check engine comes on. when dis happens, i found dat my low rev kinda stutters. im using iridium plugs no8, replaced all da coil plugs alr.

i've even diagnosed da car, from da ecu and an external diagnostic tool. which found no error, even wif my check engine light's on.

anyone ere noes wat shud i look for? shud i replace my afm? if its my turbo thats need a replacement, wud i b able to boost it up still if i rev hard? coz i did try yesterday, i rev'd it realli hard, n it boosted up to 0.9 bar. which is full boost and found da car still pulling. n when i parked my car, it releases heaps of white smoke.

any idea where shud i start? i also realised that my exhaust sensor mounting was burnt, but still useable. i cud still unclip and clip it back.

ANY IDEA? PLS HELP

dis da den wif ere shud what?

The diagnostic tool/consult whatever will tell you why the check engine light was on. Not sure what else you are trying to say?

wat im tryin to say is....

white smoke emits out from my exhaust. while im driving it, sometimes the cehck light engine comes on n off. i'd used da diagnostic tools n used the ecu to diagnose to check which sensor spoiled. but it came out all healthy.

thus what im tryin to ask is, what else shud i look for? could it be the valve seal causing white smoke? as for my turbo, there are some minor oil at the downpipe and the front mouth of my turbo.

as for compression, its all at 120-130 reading for all 6 cyclinders. so it couldnt b my piston rings, am i correct?
