I had a problem with my car - Jerking. I would step on the gas and it
would go and then "Jerk" like a big hiccup. My problem was that my plug
wires were too close to the engine speed sensor wires and was throwing
the signal from the speed sensor wires off via EMI. The code thrown was
"unprobable engine speed." Solution - rearrange wires so plug wires not
near speed sensor wire.

I haven't pulled codes yet. What is the difference between hesitating
and jerking? What difference would it make?

Hesitating or "jerking"?
Have you pulled codes?

I still got hesitation going on. Some of you have told me it could be
the injectors. Also someone mentioned checking the oxygen sensor but
that's only about a year old at the most. So, I ran two botles of
Techron fuel injector cleaner thru the engine with no results. This
after I also ran some fuel injector cleaner thru it from one of the Audi
mechanics. The stuff they use when they service cars. This was run
straight thru the throtle body. It was like a two botle thing. One goes
in the throtle body and one in the gas tank. And of course, no results.
Could the injectors be so clogged that they can't be helped with the
injectors cleaners? Is there any way to test them? Could the fuel filter
cause this? The car just keeps hesitating. Also, for some reason I never
get 1.8 bar of boost. It always goes to 1.7 but never 1.8 So I put a
little washer in between the top of the waste gate and the spring and
tested the car last night. It went up to 1.8 bar once but not again
since. So I put a second washer and still, 1.7 only. So, I don't know
what all this is related to. Is it a fuel problem? Ignition problem?
Maybe a vacum leak somewhere? Although I already checked the hell out of
the engine for vacum leaks. Would a leaky bypass valve cause hesitation?
I really don't know what to look for anymore. Any info would help.
