I have 89 GMC Sierra and yesterday I changed my idle air control valve and my my car wouldn’t start then I called a mechanic he said to unscrew it and try so I did and it worked but my truck wouldn’t stop accelerating after I went to go look at it it was broken

What was broken exactly?

The new air control value

How did you determine it was broken? Is it physically broken?

The spring popped out with the part and once I picked it up the spring flew away

Losing springs is an issue that happened a little too often ha ha.I’m guessing that you have a 350 TBI injection [engine](/topics-engine-chevy/)?

Thats true haha what does that mean ? When I had it screwed in it wouldn’t turn onOnly when I would keep my foot on the gas

Without the iac it will over rev normally. Have performed the IAC reset procedure when installing the new unit?
