sometimes when i am just cruising in any gear just at 60 or 80 so around 2000-2500rpm the car seems to start missing or surging but when i put my foot down it goes away and runs fine?
i have an r34 gtt sedan highflow turbo, 3in exhaust turbosmart boost controller and im just after a little more power, dont want to spend a fortune as the car is for sale anyhow
got my rb25 tuned and highflowed, but since then it blows black smoke when i put my foot into it, and when i just let it sit there and idle it blows a little blue smoke when i take off. any ideas?
ok heres what was done
-change oil and oil filter
-check brakes
-top up fluids
-check lights steering tyres suspension etc
-inspect underbody, hoses, belts etc
the oil that was put in is 10w-40 semi synthetic mobil formula
idles fine and only run 98oct fuel, no smoke at all and i cant remember if he did fuel filter, its the mrs car and the receipt is in her car. it doesnt seem to run rich whatsoever, what oil is best to run in the neo's?
