This issue has been on going before during ,and after a professional tune. Basically on light throttle at 3% tps to be specific the car will buck when driving, if at a standstill pressing gas pedal tps at 3% the rpm will oscillate up and down. The tuner said might be electrical might be the cams im running (skunk2 stg 3 tuner), at this point ive replaced tps several times with no solution the problem seems to arise after 180f ect.Ive attached a copy of the datalog it captured the problem at about 14:24-14:33

Where in the datalog are you seeing this happening?

sorry for the late response the car sits most the time........well some more background on the set up its on 1000 cc fic injectors e80 12.5:1 compression skunk2 stage 3 tuner cams i managed to capture the issue in a recent log i have attached........... this same issue happens after a while of driving once engine coolant temps cross 180 f and if it sits engine off for a while then i drive it again it'll be fine up until it gets a lil heat soaked again thnks for any suggestions

Have you used the correct dead times for the injectors you are using?

It appears to be running very rich.

im running the recommended dead times and set it to open loop during that last log......could it be the aftermarket iacv im running?

It could be iacv because your manifold pressure moves up and down with your tps steady i think only iacv can make your map moving like that

But as said above your afr is too rich and maybe it is the real cause of problem
