so the stuttering problem, i tried it in neutral, i rev up and it stops at 5500-6500. only when i punch it. and there is a Ticking Noise also. as it "Hiccups". well then i try to use 3/4 of the throttle and it goes all the way up. but my oil gauge is still going crazy. then uhm i look in my rear view mirror and i see a cloud of BLACK smoke come out the exhaust., i have no clue. thanks........also under my hood, when my turbo timer shuts my engine down. i hear a SMALL Hiss....like there is another vacuum leak, and my idle i just set at 1200 rpms. goes between 900-1200 rpms. so basically it moves.

 

make sure your maf is hooked up.

 

If it wasnt the car wouldnt run

 

anything else?

 

headgasket? or rings maybe? do a compression check and a leakdown test is my only thought at the moment I am tired though so I maybe can think of more later

 

imma end up sueing the shop, they said its fixed, but after 2 monthes. it has the SAME problem.

 

sounds like you may have one or two burnt or bent valves from incorrect timing, or like emonz says, you may have oil getting into the combustion chamber by way of worn rings, or a head gasket.

 

thats what im thinking.

 

mine did that before. i replaced the denso iridum plugs with ngk plugs and now it runs fine. try that first its a pretty cheap fix.

 

did it do it constantly before the change?
