- Random Stall Issue - Holley Performance Products Forums
My car was idling and warming up and just died The only odd thing I see in the datalog is a slight increase in voltage just before the car died I wouldn't think that a 0 1V change in voltage would upset the ECU, but I could be wrong If this is the issue, what are the recommended remedies?

- Issue with fuel pressure, need help. - forums. holley. com
I've got a strange issue with my fuel pressure When I turn on the ignition the pressure is about 43 psi, but once the engine starts it's 60 psi The fuel pump is in the tank, and the pressure gauge dial is in the engine compartment just before the fuel line goes into the Sniper Any thoughts why this is happening?
- IAC Constantly Returns to 0%. - Holley Performance Products Forums
If the gap is great, say your idling at 1% and your Hold Position is 30% and you slow tip-in on the throttle, when you reach 2% on the TPS, the IAC motor will jump to your Hold Position and depending on the speed that happens, it'll feel like you pushed the throttle pedal more than you had intended to

- Idle is LEAN suddenly. - Holley Performance Products Forums
The other day it started idling at 15-16 AFR and running rough once hot Closed Loop was adding all it could, 5% per the limit Idle speed was still around target I noticed IAC was a bit elevated also 1) Misfire? 2) Vacuum leak? Wouldn't the idle be higher? 3) Exhaust leak? Runs fine above idle and still has same power, etc Thanks, Matt
