So I am ready to set this car on fire. I put it away at the end of the year last year and had no problems. I brought it back out this year and I noticed the o2 housing was broken. Did that getting it in the garage. Installed a new one with a Tial mv38 external wastegate and I started to notice a slight hesitation at 2000 rpm. Now I have a big hesitation and can't figure it out. I thought originally it was the fuel filter so on with a new golan fuel filter, and new 255 hp pump. Problem still there. Loging showed nothing abnormal so I decided to swap maf sensors. I am using a gm maf with MAFT. Problem still there. Swapped out the CAS from a know good car and still there. Went out and tried retuning the car and nothing. I thought maybe the translator was going bad so I unplugged it and drove the car. Problem unchanged. I am pulling my hair out. The logs from dsmlink look good. It goes super lean when it stumbles but injector duty cycle stays the same. I was supposed to autox tomorrow but not if I can't get it fixed.
