I appreciate the help that I've gotten so far. Any addition input out there?

i read thru the thread and it does seem you have some fueling issue. Your AFR looks where it should be but youre getting those codes for misfires and bank 1 afr being off.

i would log cylinder misfires, knock correction, port fueling injection ratio, injector D4S mode. i'll look at the rest of the parameters when i have a look later

Catch can? I assume you are referring to the oil accumulator. I'm not sure that I need it but Element Tuning recommended it.


I'll see if I can find an O2 sensor.

No, the oil accumulator is good, have one myself.


It's this that I was commenting on, looks to be a tin can of some sort. Is this in your vacuum loop path? Could be causing problems if it isn't really sealed...

The tin can is my smoke machine.

I replaced the MAP sensor, drove it across town a couple of time and then pulled a log.

I still can't tell one log from another. I have a replacement O2 sensor but will wait and see how the new MAP works out.

I've replaced the upstream 02 sensor, MAP, and MAF. Checked for vacuum leaks with starter fluid and "my" smoke machine. 0219a and 0119f (occasionally 0304) still pop up every few drive cycles. I give up. In Jan, I'm taking it to PTuning.


All right PTuning, it's on!

The saga continues. Took the car to PTuning. On the dyno, power is way down 150-160hp at 3500rpm. Rich afr. #4 shows intermittent misfire. The tuner starts tuning. Everything seemed to be working nicely. Then, my Driveshaft Shop aluminum driveshaft breaks in half. No warning! No NVM. Nothing but bang and clackity clack sound coming from the dyno room. PTuning is going to source a stock drive shaft and finish the tune next week. I'll pick the car up next Friday and we'll see what happens next. Great folks at PTuning though.
