My car idles pretty steady at 800rpm when at a stop. But while shifting gears (5 speed) or going into nuetral while coasting to a stop, the idle will rise to around 1500 or slightly higher and glhold there until around 5mph or a complete stop. Then go back to normal idle RPM.
Not sure what the issue is here. TPS is adjusted and IAC is decently new. Nothing else in on the TB as it is a 75mm Holley and a EGR Block off plate as well. No check engine light or other issues.
When I have tuned AEM EMS on other cars, this was a setting. I could set the high idle to be active or deactive at a certain MPH, load, and other thresholds. But I am on the stock computer and MAF as well. So I am unsure what may be causing this issue.
Any ideas?
