Completed the oil change and pulled the MAF sensor that was gleaned from the Pull & Pay. Sprayed this down with the CRC maf cleaner and made a difference. Smoother idle, more power and less hesitation. Thinking of investing in some Seafoam and pour this down the intake and put the rest into the gas tank, as others have reported. Seems that everything that has been done has made an improvement in performance and gas mileage. Am looking to pull the injectors out of this in the future. Anyone here have some good advice to give? Thanks, Steven.
