I have a 1995 Ford Explorer 4X4 Eddie Bauer Edition. It is idling around 550-600 RPM's in Park and Neutral and 475-500 RPM's in Reverse or Drive and causing the truck to shake. I thought it may have been bad gas but I have ran it down to a quarter tank and filled with Chevron gas and fuel treatment since then and it is still doing the same thing. In the morning when I first start the vehicle it will run smooth until it warms up or if I change the gear.
Here is what I have done so far.
*Checked Vehicle Fluids
*Checked for Vacuum Leaks
*Changed the Fuel Filter
*Changed the PCV Valve (It was no good)
*Changed the Idle Air Control Valve
*Cleaned the Throttle Body
*Cleaned the MAF Sensor
*Oil Change Performed (2 months ago)
*Spark Plugs Replace (4 months ago)(Did not change wires)
Thanks! I hope I gave enough information that someone can help!
