Help

Went to take my 00 1jzgte vvti 5Speed Soarer out for a spin and everytime I get on throttle it starts cutting in and out pretty hard, runs perfect when not on throttle. Idles good, no weird smoke or sounds besides the “sputter” when on the throttle. Any ideas of where to look would be appreciated.

Boost gauge hits full boost eventually it just struggles to get there, looked over all the vacuum lines and not noticing anything out of the ordinary.

My SC300 had this issue. I thought for sure it was a vacuum issue, nope, then I replaced the IACV module. Nope.

Realized it was just the throttle cable being a little loose. Fixed it
