Hey all, scratching my head on this one...
Truck starts fine, fluctuating between 500-600. drive it around and notice the idle/cruising RPMs seem high. Come to stop and truck idles at 1000-12000 throw it in park and climbs to 1500-2000. I noticed I can stab the throttle and idle will drop. If its idling high and I shut off the truck, it restarts just fine with normal idle. Then starts having problems starting, doesn't fire right up anymore, crank for 5 seconds or so and nothing, stop and crank again, fires in a second or so but low, almost stumbles, and climbs up to normal.
Pulled codes:
KOEO: 111
CM: 111
KOER: 411 - uncontrollable idle, usually high (re test and got 111)
Disconnected IAC, lowers idle a bit, seemingly no more high idle, then comes back about 20 minutes later. Doubt its IAC, but clean anyway.
Cleaned MAF
Checked TPS - normal (.98-4.64 iirc)
Changed BOTH temp sensor and sender, gauge works.
New T-stat
Checked VAC with carb cleaner, no change, no leaks
New PVC
sprayed carb cleaner around intake, intake tube, everywhere and got nothing and no change in how the truck runs.
did notice a crack in the intake tube around the bellows after the MAF, but it "closes" since its in the inside of the bellows, reinstalled and sprayed area with carb cleaner, no change either. new tube on its way anyway.
truck runs fine otherwise, besides a bad fuel gauge or sending unit. And what im hoping is a bad servo in the trans (second gear not engaging) please let me know anything else I can check or ideas. Thank you in advance.
