SR20DET Cuts Out
I am stuck and could use some help.
S13 SR20DET 550cc injectors z32 MAF s15 turbo Power FC 255 fuel pump Went to tune the car, when i'm wide open throttle the car will randomly cut out. Boost drops into vacuum, and AFR's don't change. It does it at random RPMS, but only when full throttle. I can hold my foot to the floor and it will remain cut out, until I come off the pedal and get back into it. I can creep to redline partial. Can't do it full. At idle I can rev the car to the moon. Only under load does it do this. The tuner says everything looks good on his end, no sensor failures or anything out of the ordinary. I swapped in another AFM, as well as added multiple new grounds. No fix. |
