When I bought the car it had 9 codes...
Well, I've fixed them all so far except these two reoccurring ones... And it's weird.
I have a Cobb Accessport (I'm running a stage 2 map. Intake, turbo back exhaust, STi intercooler) and some generic OBD-II scanner. Both of them only read one code. But they both read different codes.
The AP reads P0444 (Evap) issue. The car (previous owner) has a deleted Evan system. The air filter and intake ports have been plugged off. Only one vacuum line that I can find leads from the deep middle of the intake, up into the top middle nipple of the intake. I've searched online and it looks like it's been done properly. But I see the connector just laying there with nothing to plug into.
So I have no clue what else I can do with it. The OBD-II on the other hand is showing up a P1088 code. A driver side TGV sensor going bad. I JUST fixed my P1089 code (TGV sensor on the passenger side.... Pita!!!) So now I have a TPS sensor on the way to replace this one. But I'm afraid after I replace it... Nothing will change.
The car cranks up and idles fine. Maybe idles a little low sometimes, but nothing unusual. (replaced the IACV) but even when idling, if I give it gas, it's like the car "stumbles" or hesitates and feels like it chokes out. But as soon as it gets over the stumbling it revs and builds boost perfectly normal.
When driving, I'll change gears and the car will act like it's choking up, and stutter (the car literally feels like it's jerking back and forward) and then starts revving normally and builds boost fine and takes off. All is good until the next gear change... Then the process repeats.
If I let off the clutch VERY slowly and smoothly, then apply the Throttle VERY slowly and smoothly, it'll pull fine without jerking. But if I quickly stomp it, it'll choke up and shake back and forth. It's super frustrating.
I literally can't figure it out. And the sensor won't be here til Friday. So my fingers are crossed that it solves my problem, but I feel like it's just another wasted effort.
TL;DR: Car idles fine. But "chokes" when given liberal amounts of throttle, stumbles at first, but then gains RPMs normally and builds boost fine after it revs out of the choke. Does this at idle, and after every gear change. Replaced passenger side TGV sensor, IACV, double checked the EVAP delete, and STILL can't figure it out!
