OT: Solving my 01 Jetta 20vT Problems??

[vw_85roccoZ400 at hotmail.com (Brian Spinney)]

Alright some of you might remember my recent problems... Subject line *(Damn 
Volkswagen Coil Packs)*

Well here are the new problems beside the problems from the past... my car 
just started having troubles with rough idle, lower gas mileage, bad 
hesitation..  So yesterday on my way home from work I pulled into a parking 
lot.. I unplugged the MAF sensor...  Car rough idle went away... So I 
figured what the hell drive it the rest of the way home like that... 2 
miles...  Holy night and day differences...  So I left it unplugged for my 
trip to work today.. 25 miles and even on the Highway wow feels like a new 
car again...

So I think I have finally got my problem figured out and the problem doesn't 
seam to lie in the coil packs..

I'm about 80% sure that my problem is MAF sensor... I didn't want to make a 
post, figuring my answer would be Use the Search Function..  So I spent the 
greater part of my morning searching vwvortex achieves.

This is the only information I found worth anything....
If the MAF is unplugged, the engine ECU will assume a default approx. 550mg 
of air.
So, if your engine actually runs stronger after uplugging the MAF (it 
assumes more air and thus pumps in more fuel), it would definitely be your 
MAF that is failing.
