tbi surge

Hello all,

My tbi build has been better than expected but recently i have developed an issue where when decelerating my engine will surge. It feels almost like i am driving gas,brake,gas,brake.

I checked all the basics and did a little data logging and can not find anything. I thought it might be the 4l80 locking and unlocking but the MSD controller does not show any signs of it.

Has anyone ever come across this? I posted over at 3rd gen and gearheads but i did not get any responses.

Thanks,
Chris
