Default Car Hesitates, misfires, stutters. Log attached

Car is acting funny over 3k rpms and sounds funny across the entire powerband. Exhaust note is off. Please take a look at attached log to see if you can make anything out. Thanks.

EDIT: it won't let me attach log... How can I attach a log?

Wonder if you're having the same probelm I had...

Is this after a reflash only or did you perform any physical mods on the car?

I ask because after I installed my VF39 turbo one of the TGVs was re-installed incorrectly and the car ran like complete ***** over 3k RPM.

Timing belt cover exploded, so I had the timing belt replaced. Still tension on the belt, and it was in time. Shop has checked timing 3 times already and it's in time. Compression and leakdown both OK, plugs gapped correctly. No CEL either. Nothing else was touched. They're going to put a known working crank sensor to see if that's it.

It was working for over a year on this map before the cover grenaded.

Well, nothing wrong with the car before going into the shop, but it runs like crap after leaving the shop. You replaced ALL your coils?

i had a cel for cyl 3 misfiring 6 mths back and told them and got lucky i guess.
but when i had the stutter issue, no cel was to be found.

try to swap out the coils with a spare from the shop if you can.

Well, I think they found the problem. My map had TGV codes disabled, and it appears to be a failed TGV sensor. I'm not sure how in the hell it's related to timing belt install, but it died. Thanks for the help.

Those sensors are very fragile, and they are in a vulnerable position.

So they fixed that problem, but now there's a crack in the radiator. This shop is my car's CURSE.
