My s80 has ran perfect other than a lose of power at WOT and it would seem as though i was on the pedal and letting off repeatedly and i wasnt. My mechanic told me it was my tps and he took it off and had me clean it because it was black. I got it sparkly clean handed it back he put it on and since then my car wudnt run. The MAF i found out had no wire in it so i dont even understand how i was driving it... When i unplugged my maf it wud run perfect although after fiddling with it i somehow got it to run with it and i took it down highway and i did 125 and it was PERFECT i loved it but when i saw 125 i saw my oil light blink a couple times so i got off the next exit and checked my oil and it was low... I put oil in it and my car doesnt smoke or make any odd noises but it now seems i have no turbo or no power and my car kept stuttering and stalling so i finally took a mass air flow off a parts car volvo i have which is a 2000 volvo s80 2.9l non turbo and put that on my t6 that made my t6 shut off a few times till it warmed up and then it drove but if i put it to the floor all i hear is my engine reving and yah it goes fast but NEVER like it used to and it feels as though i have no turbo... Also i have no codes so far at all i did however have a code but i reset battery and then i had to drive home and i drove it around a bit more and it has yet to pull a code. Also that time i did go 125mph on the highway when i got back home i realize the clamp to my turbo near the intercooler was covered in oil and maybe my clamp was loose but now i have no power and i have been spending days on trying to figure this all out.. ALso my idle is all wacky especially when its cold... it sits at around 800rpms and when i do hit the gas at an idle it sounds like my airbox or something is off... im just so lost with this... cud it be that my mechanic forgot to plug tps in? or Maybe i thought the Turbo control valve being junk? or maybe even the mass air flow doesnt goto the turbo s80 just the non turbo?! My car has 96,338miles

 

maf are different from those two cars. put the right parts on and go from there. hope they are wired the same and you didn't smoke the computer.

 

dirty/ under reporting maf sensors will cause problems mostly when the engine is cold because the o2s are not looked at till the engine is warmed up.
