Yes, i have lubricated them but i absolutely have not adjusted them properly.

A side issue, I would recommend washing your engine bay so you can see if you have anything actively leaking which could become part of the diagnostic process.



When this happens, try switching into neutral and push the accelerator. Does the engine rev up? If not, you have a throttle or linkage issue. If it does, you have some other problem. Is your air filter clean?

I would not necessarily put these two issues together. Go back on whatever you have been wrenching on and see if you left anything loose. If that doesn't yield results, check each component under the hood for play with the engine off and see if you can manually re-create the vibration sound. Also try pushing the engine back and forth and verify it is fully seated in the motor mounts. Also check the tightness of the belts.

None of the belts or pulleys should have any effect on the engine performance.

I would say the turbocharger failing is probably the last thing to inspect. Have you made any adjustments to the ALDA?

Also, I would recommend doing an Italian tune-up at some point. Find a highway or somewhere you can drive at high speed for extended periods of time. It will do wonders to blow carbon out of the system.

Good stuff


So yes, when in neutral, i have all of the power (or so it seems). When in gear is when it gets funny.

My #3 injector is leaking at the halves and also a few of my hard lines are leaking where they meet the injection pump. So i need to fix all of that. That is where 95% of that wetness on the engine is coming from. That plus me spilling stuff on the engine

Engine mounts are SHOT. At certain RPM's, i can visibly see my hood shaking tremendously. The whole car rocks side to side. I think i have an engine shock as well on the drivers side, no? If so, it is shot as well. I plan on replacing them ASAP just need to figure out how. I've done engine mounts on my E63 AMG so i doubt this car will be too much of an issue

Belts are tight, the PS pump belt is slightly loose and here lately my PS pump started screeching when at full lock when first starting the car.

I took a picture of the ALDA in it's stock state, adjusted it to about 1 turn CCW, did not notice a difference (this was on the old injectors). So, i ended up turning it back to around where it was when stock. It had never been touched, the little black cap had to be removed. I actually turned it back a little the other day, but were talking like a 1/8 of a turn CCW from stock.

Did the italian tune up last night

Actually smoothly sailed up to 90mph with no issues (except that injector leaking fuel)

The car runs tremendously minus this screeching/loss of power

EDIT: meant to add this. The wheel on the front of the turbo (sorry do not know much about turbos) does not spin very freely. If i spin it by hand, it will stop spinning within 3-4 rotations. Like it has more resistance. Most turbos ive seen will just keep on spinning for around 5 seconds. Is this just because most of the turbos i see are brand new, where this one has unknown, possibly 300-400,000 miles? Or is that not normal
