i have a 95 12v auto with 216000 miles. I just got done replacing the famouse kdp and fuel lift pump. Afterword i was driving it and it ran just fine then all of a sudden it started stumblin at anything higher then at idle and blows continuous ewhite smoke that burns your eyes. There isnt Any fuel lines leaking or sucking air.

 

Does it smell like oil? Check your turbo, if the turbo is spinning smoothly and has no shaft front to back movement. Then check you coolant, make sure you're not building pressure.

 

sounds like your timing may have slipped

 

x2 on what they both said.. check your turbo first to make sure it didn't kick the bucket since it'll be easier to do and then check timing if it's not the turbo

 

whats the best way to check the turbo? And the smell of the fumes smells strong i jus couldnt bare to breath it in without gettin all choked up but it burns your eyes and throat

 

pull your intake off the front of the turbo and sorta smell it and also see if your wheel moves back and forth of up and down if it moves more than half an inch im going with that's not good

 

Does it smell like oil, or does it smell like coolant?

 

smells like diesel its bluish colored, me and a buddy jus got done tinkerin with it and its still runnin rough. the turbo is good but idk if the injector pump is going bad or if its injectors we placed the motor a TDC and put the injector pump back in time but did no good. The injector pump was pumping out of all the lines up to the injectors . He thinks the fuel filter is stopped up but im guessin its injectors since its idiling just past the first mark above 0

 

timing and i would check your injectors,

 

I agree timing and posible injectors.
