93 Grand with rough idel, and seems low on power.
Just bought a 93 Grand last week for $1500. New paint, 31" BFG's, Eagle Alloy wheels, awesome interior, cold A/C. This thing drives good but seems to have a slight loss of power from other Grand Cherokees I have driven. When you are at an idel, arround 500 RPM, the engine seems to have a miss. I cleaned the throttle body, cleaned the IAC valve, checked plugs, wires, cap and rotor. Seafomed through the throttle body. Going to check compression today, but due to the plugs looking near perfect, I suspect that the compression readings will be fine. Engine has 120K on it. I have not changed the fuel filter yet, but plan on it today as well. Any other sugestions?
