135,000 miles and started noticing random problems with the cold idle.
Usually fixed itself when I tapped the gas. No other funtions seem
affected. No, the truck barely starts and i have to keep my foot on
the gas. Once warm, it barely idles below 500 rpm. Also I notice a
high-histle sound at 2500rpm like a blow off valve. The truck is well
maintained and replaced plugs, wires, all filters recently. NO CHECK
ENGINE LIGHT ON

Any Ideas?
