High idle

[xanatost]

My 98 Tahoe after it warms up will idle high when I put her in park. Has anyone ever run into this problem? It's not all the time but it's enough lol. I have checked for leaks around the I take and checked the wiring and everything looks fine. My next idea would be a fuel pump or fuel presser regulator. How do I test those?? Thanks

fuel pressure test port is on fuel line on top of engine. are you sure your iac valve is not stuck? maybe you need to reset it.

How do you reset that??

NM I found it. I'll check that tomorrow and see if that fixes it. Thanks sun
