Truck is slow to idle down
Took advantage of Sept. blower port special. Had some Brisk plugs and a 4# lower on hand and decided to do the plugs while the blower was off. Save the pulley for later as to not get too many things going at once. Intercooler has some residue after 7K miles so lazy me decides to hit it with some carb cleaner without removing. I reasoned that I would not be flushing much crud into the intake valley and most of the carb cleaner would evaporate before I had it all back together?? Well I guess it didn't because she smoked for a couple minutes on the initial startup. Right away while driving normally I noticed a difference. At 20-30 mph letting off the pedal the truck seemed to continue pulling ever so slightly. Thought hey maybe these Brisk plugs are the shiznit?. Or cleaning up the throttle body maybe. Then I notice that the idle at startup seems to have changed. Higher initial rpm, 16-1800 , and it hangs at 12-1300 for 3-4 seconds then drops to 8-900 and eventually settles at about 750. Cold or hot does not seem to matter much. While still in park the slightest tap of the pedal (and I mean the smallest rev you could possibly give it) the rpm goes to 12-1300 hangs 3-4 seconds then creeps back down to 750~. Takes probably 10 seconds from the tap of the pedal to idle back down. Also notice the exhaust tips are getting black alot quicker now. This would indicate the truck is running rich correct? Could this be from the plugs or all the extra idle maybe? Did the carb cleaner screw something up? Predator says "no trouble codes found". Is there something that I can monitor that might indicate the problem.
