car is running like ass!!!

[gmoney]

Ok i have had a problem with my car for a couple days now, i cant get into boost at all because all the car does is stumble, black smoke comes out the back its not cool. when i do hit boost its only 5 psi till about 4 grand then its back to bucking. there are no ic leaks, checked the wastegate i have no clue what it is but its pissing me off...

well this one sounds like plugs also. CHECK UR SPARK PLUGS.

will do... i hope its small even though its coming off the road this week to get rebuilt.

 

[aye mate]

Check for boost leaks, but I'm guessing you already did that. BOV adjustment?

Sounds like a boost leak to me. Any codes? Does it run good off boost?

not really the whole car runs like crap and the other day i popped the hood and there was oil everywere... so i duisasembled everything and checked the turbo and its got a little shaft play not to bad but enough to upset me, but the oil lines were atached to it. but the mbc was detached from the wastegate...so i fixed that by removing the mbc hoping that would be the end of it but it wasnt...

Check to see if the spark plug galley is full of oil. That usually causes problems for ignition, not to mention the mess and loss of oil.

yea, that might not be a plug problem if ur engine is full of oil. something isnt right.
