r33 running rough and blowing smoke

[kyler33]

i have a r33 gtst and its idling rough and relly rough when i turn the air con on. and when i drive it it surges and cant hit boost and poors out smoke. any thoughts?

[NZM.031]

what colour is the smoke???

if its black, you could have a busted intercooler hose, it will be running super rich and go like a shot cat (after it dies), id check that first..pull the intercooler pipes out and inspect them and the rubber hoses.

i had a similar problem and it turned out to be the 90' rubber hose under neath the air filter.

mate its an easy fix

open the bonnet & give the pfuff pfuff valve a few twists.

should be right after that

check your cooler pipes first, and if that ends up being the problem, check your plugs to make sure they aren't fouled

the plugs will be as black as Samuel L Jackson if a cooler pipe is busted, check the plugs for damage, make sure you know which cylinder each plug came from, could be a coil pack problem also. if the plugs are all uniform in colour but then theres one thats different, that will be it. try putting that plug + its coilpack and run it, see if it continues to play up, remove it and check the colour again. if its the same, seperate the 2, put a different plug with that coilpack, that will tell you if its the plug or coils.

depends on what blow off valve he has andrejp.. he hasnt said what mods it has, might have a hks one or something which dont leak.

it all depends on colour of smoke, if its white, or bluish, then could be a busted piston ring or worse.

post up the mods and conditions before it happened.

I see you live in Mackay? What colour is your R33? I would suggest taking it to Damo at LS1 Proformance at the end of Victoria Street.

Could have unplugged the afm or something too

Look at your ECU and see if it's in limp mode (the LED will be on when the car is running).
