2000 Ranger Knocking at Idle
Any help would he appreciated I just can't figure out where the noise is coming from or what's causing it. Only happens at idle about 20 seconds after its started. I started noticing the noise after I got a cheap oil change at Firestone. I drove about 1,000 miles on their cheap oil before I found the time to swap it out for the good stuff. Check engine light is throwing P1309 which is engine misfire detector monitor not enabled. This happened after I had the shop swap out my squeaky camshaft synchronizer. Computer shows no misfires. New spark plugs, alternator, serpentine belt, brake lines, power steering lines, power steering rack, water pump, PCV valve. No metal shavings in oil. Already seafoamed the injectors.
