Ok My car bucks uncontrollably at any time at any rpm range in any gear in and out of boost.

I took my AFM off and used a multimeter to check factory specs. It failed horribly on all of them.

To get my car to and from work and school, I put my GTU's AFM on. It got the car to go and drive fine.

They bucking came back

I checked the AFM and it's only out of sync by a bit. Would that really screw it up enough? It's not as bad as it used to be.

Think I should buy a new N370 AFM? Autozone told me 200$, anybody know any good OEM part dealers online? Thanks again!

The bucking was searched, the OEM part dealers were not, FYI. No flaming!

 

My N/A was doing something similar at idle. I had a leak after the AFM.

You could prob find an afm cheap on this site.

 

Would I be better off buying a new one than risk buying another old worn out one? Could it just be a vacuum leak? I have no TID, just a stupid hose. I bought the TID and have yet to put it on because I have no room due to my FMIC. The FMIC is coming off soon.

 

Throw up a "WTB N370 AFM" in the second gen parts wanted section. Probably be a lot cheaper than $200.

 

Check your factory intake tube. It is prone to leak. It is a 2 peiece setup.
Before buying an AFM check for leaks. Also buying one used is much cheaper and these parts are not known to fail.
