I'm not quite sure how to post threads or where to put them or any of that, kinda new to this but i have a problem with my vehicle and need help...
My car drives great mostly, i can drive it like a daily driver without any problems at all, cruises fine, my problem is only when i come to a complete stop and then hit the throttle fast, i don't even have to floor it, just hitting it fast will make it stumble like it dies for a split second and all my gauges go whack and reset like the car is starting up like i just turned the key to crank it(gauges go all the way one way and back to the other).
Like i said, if i just drive it normal, no problems at all, even if i'm already cruising anywhere above 5-10MPH and slam the throttle it'll get up and go, no stumble, its only when i'm at a dead stop and do it...now as far as letting you know what all i've done to the car...
255LPH fuel pump
fuel tank itself
cold air intake
i've taken apart every electical connector on the vehicle i can think of and sprayed them with electrical parts cleaner(CRC) and cleaned mass air flow sensor also.
one thing i've noticed is the throttle position sensor(TPS) has 3 wires and one of them is frayed, i've cleaned out throttle body itself too.
My guess is its the mass air flow sensor(MAF) or throttle postion sensor(TPS)
The vehicle also has a SCT tune in it, but problem persists whether i have the tune in or reverted to stock.
I will upload a few datalogs i have of me smashing the throttle from a dead stop, it only monitors MAF counts, air flow, and fuel rail pressure.
Any help would be appreciated, Thx
