weird cel problem

[95whitegst]

ok so today while driving around i boosted it a little getting on the highway not full boost only about 10 pounds, and my cel came on real quick and it felt like i hit fuel cut and my safc said in the karman part only 3hz. about 3 seconds later it went away i gave it gas and it boosted fine again for then next hour or so then came back randomly and does this every now and then im lost

do you have any logging software or way to scan it. I think it might be a fuel thinh. Maybe fuel trim malfunction. Mine use to do that randomly.

i dont have a logger, only thing i have is my wideband and my safc and the maft.

It sounds like a bad connection with the MAFT. If your Karman Hz went to nothing for a second I would suspect a loose connection. Did you solder the connections, or use vampire clamps?
