Hi everyone I'm new here.
Last night I turned on my mustang it's a 90 5.0 5 speed. And the car tunred on and everything idles normal no check engkne light or anything it's perfect and as soon as I let go of the clutch the rpms shot up to 1500 and check engine light turned on as soon as I hold it 3 seconds later it turns of and rpms go down I've been trying to fix it and nothing I changed the iac it didn't do anything and also checked for vacum leaks and nothing. I'm seriously lost
