Anyone have thoughts on this. It goes extremely lean, only when the scanner pid goes to "in gear" and i verified its not related to ve hitting a bad spot by unhooking the park position switch so the pid shows in gear when in park, with the same results. As soon as it sees the pnp switch show on gear, this happens regardless whether its physically in gear.
Speed density. Maf failed 0hz. Maf failed first key cycle. And set maf rpm.for filtered maf fuel mass to 10k rpm, and theres no maf wired in physically. Ive tried both open and closed loop. Fuel trims stay within 5-7% when it occurs.
This video i even started over and tried a manual OS and its the same issue, only difference is with the manual OS i dont get stalling in gear, and once back in park the afrs dont recover like it did with the auto OS.
Its almost like its on a timer. Always about 10 to 15 seconds after shifting to gear it happens.
Car is a 355 lt1 running a torqhead kit and 0411 pcm, non electric 4l60.
