Audi0s

You probably got the green plug coolant sensor, which works on all b6 and up audis and most vws from arond the same time. You need the blue or black square 4 pin. ecstuning carries them I think, as well as genuineaudiparts.com

Really?! That sounds more probable, I mean like the thing like creeps until 2000rpms (even when floored) and then it goes but still not as peppy as it should be. It tops out at like 80?! Does that sound similar? Which lines were collapsed? Can I just clean the PCV valve? Also there seems to be an abundance of oil in my charge pipe? Also I just purchased the PLX Kiwi Wifi datalogger/code scanner for iPod/iPhone I'll let you guys know if it's worth the 149.99$ Sorry for all the questions btw. Thanks for all the input so far!

Could it possible be the suction pump? says "When clogged, builds pressure in the crankcase" May be causing loss of oil? Seems when at operating temp a lot of the oil is atomized and comes out as a mist from under the hood. Just noticed this last night because it was dark out. Sorry for the double post.

It sounds like there's something more significant than PCV, suction pump, vacuum hoses, etc. Those things won't make the car a dog that tops out at 80. You could have turbo trouble, or a defective throttle body, bad MAF, fuel pressure, etc. Could be a leaking induction system hose or any number of causes. You've got to get it scanned for starters.

When read with a normal reader it only comes up with the CTS. Would a VAG be able to find something else? Boost now bounces from 5 to 7 to 11 whenever it feels like it :/ I know these cars arent fast stock, but if one of you drove it I'm 99.99% positive you would be like "WTF?!" At idle in "Drive" the vacuum is only at 14lbs? Suction pump is now clean I think(the side pipe is the only one you shouldnt be able to blow through right?)It also gets horrible gas mileage (16-17 hwy). The rings seem to be fine, no blow by and decent compression. Once again sorry for all the questions and stuff but this has been one giant headache for me, and I just want it to run like normal also the tranny seems to kind of "thump" when down shifting. Not so much of a sound but a felt bump in the drive. If I let off the gas, after being in say 3rd gear at 3000rpm it sits there for like 5-10 seconds before it upsifts and the rpm's drop :/. Im thinking my winter beater might be a winter money hole...

UPDATE
Had the trans serviced-new fluid,filter,pangasket, and seals.
Also got new 02 sensors, had the rear diff serviced (new seals and fluid)

Drives a LOT better but is still very sluggish and hesitant.
The mechanic at the trans shop said when he drove it the G/S were very low? I have a data logger so I can view and record these readings. My question is what should they be at, and could the MAF/Throttle body be causing this if the readings are very low? Also what should the timing advance/retard be at at idle?

Groveguy89

g/s maxed out at like 92g/s WOT at redline
Throttle Posistion sensor reading bounces but car runs smoothly?
timing advance at idle is +12 degrees and around +25-30 at WOT

Please tell me this is ringing a bell for someone out there?
