i was under the hood looking for a slight miss i have and noticed the pcv hose is completly collapsed right where it goes into the throttlebody. i pulled on it to try to straighten it out and i felt and heard the valve click.
i held the rpms at 1500 where my miss is at and it didnt seem to change the shaking of the motor when i pulled on the hose. would this hose being collapsed cause a miss? i changed plugs a month ago to tr6,s, havent done wires yet. the car shakes in 3rd gear(a4) almost always, and in park at 1500 rpm.

just replaced the collapsed hose and the motor still shakes at 1500rpms.

PCV should be mixture-neutral unless it's off and
letting air in. I see 28# injectors on the 2000 car,
is this tuned in properly? Maybe needs a little
more tweaking?

thats a very good possibility jimmy. i had speed inc tune for them but it was mailorder not dyno. im also wondering if they removed TM. it feels like theres a hesitation before the shift still. im not sure if its a miss im diagnosing or a converter/trans prob.
car shakes in 3rd at almost any rpm but more so as it gets closer to shifting into overdrive. i can feel it in sotp and especially in the steering wheel. normally id think its the wheels out of balance,but i can slow down and it still does it while in 3rd gear no matter what.
when going from 3rd into overdrive its gone instantly after the shift but returns once i reach 70 mph plus. when i sit in park and rev real slow it shakes at 1500 then again at 2000-2500 or so. im wondering if my flexplate is bent or cracked. car still performs fine and launches hard. i have till july 5th on my flp trans warranty if im going to look into the trans maybe having a issue.
