Bad Throttle Response..Doesnt accelerate like i want it to
alright, heres the deal. i have good throttle response if i dont floor it. but if im cruising and every now and then i wanna feel the power, i floor it. but it seems as if it barley accelerates. its like im better off pushing the petal slowly. its like an off and on thing. sometimes it wants to take off and most of the time it doesnt....
any ideas? had a tune up not to long ago. this year. (fuel filter, plugs, plug wires, oil change w/filter as well, seafoamed) also changed the PVC valve, fuel regulator, TPS)

Try cleaning the MAF with CRC MAF cleaner, don't use throttlebody cleaner on the MAF. Make sure its MAF cleaner. CRC is the only MAF cleaner that I've seen. Its in a silver can.

Never hurts to disconnect the battery when working on the truck. Also I would take off the throttlebody and clean with CRC throttlebody cleaner and a SOFT old toothbrush.

Also taking a look at your fuel pressure wouldnt hurt since it seems that when you floor it the pressure isnt there.. Also a Throttle position sensor sweep test would probably be a good idea since a weak or bad TPS can also rear its ugly head and when you stomp on it the TPS doesnt tell the computer that you have the throttle opened all the way.Mike

It never hurts since im pretty sure the vast majority would agree its not the first time that a replacement part failed.
