Why is my vehicle idling high?
1995 Chevy suburban k1500 will idle high most of the time. Between 900-1200rpm on the lower side when warmed up. Sometimes it will idle 750 properly. First startup in the morning feels like it's struggling to get speed. Drive for a bit and then restart the vehicle then it will sound right and get the power but still idle high. No check engine light. New spark plugs, spark plug wires, cap & rotor, egr valve. I have a new fuel filter as well that I need to replace.
