exhaust tips white

[GeeSTee]

I do beleive Im running lean. Car runs and drives like poo. Its almost like an injector isnt goin, but I checked them all. Possibly fuel filter, or pump? Felt like a loose hose but they all seem in place. .. Dank u..

The only time my tips turn white is after running race fuel. Has anybody been using race fuel? If so it seems odd that the tips would be white even if it is running lean.

No race fuel has been used. I thought white inside tips indicated a lean condition, or is it rich?

White indicates lean, black indicates rich. I would pull out your spark plugs and have a look at them.

i did check the plugs and there clean. What are some suggested steps to take on a lean turbo car? This is my first turbo and I know how touchy they can be. Besides fuel filter, pump, injectors.. what other things to look for?

can u actually c the white smoke comin out of ur pipe? it could actually mean a lot of other things too. it doesn't necesarily mean ur runnin lean. it could mean ur engine coolant is leaking somehow into the exhaust stream......it could mean ur head gasket is blown.......it could mean ur turbo is shot. does the exhaust smell? does the car pull like it should? too many questions?

The car will run fine seconds on and seconds off, it falls flat on its face (little to no pick up) and then it picks up again and its fine, then back on its face. The turbo is making boost, and for those few seconds of running well it pulls like it should. The exhaust is minimal, its barely noticable. Ive had my share of bad pumps and filters on other cars and this doesnt feel like the problem.

I unplugged each injector one by one, and it ran similarly crapy when a single injector was pulled. but it didnt seem like one specific injector was the problem.

EDIT: exhaust doesnt smell
