Hello! I have some issues with my idle and low pedal acceleration is a bit jerky.
I have 70mm tb, smoke tested intake, changed all the vacuum tubes, tried 3 different IAC valves and nothing, right now im running with a blocked iac.
With oem iac it idles right, but it jerks during acceleration, while it jerks it fluctuates on the vaccum gauge i have.
With replacement "Walker" iac it idles at 2000rpm.
With replacement oem but 96-00 PN it idles perfect first minute, then 2000rpm.
Tried resetting the TB with the gauge and 0.93 same, tried with 0.96 and same.
With iac blocked or disconnected it backfires from exhaust on deccel badly.
Here´s a video of the vaccum gauge.
