How many miles do you have on your truck? When I cleaned out my throttle body my throttle response from a stand still changed big time. My truck use to not move at idle. But a programmer will do you some good as well. But clean that throttle body!!

I for one was serious, I had never heard of this and wanted to know what it did to the system so thanks for that explanation. Anything to improve my performance or mileage is worth investigating. That is how I learned about the EVO and Gotts, both very positive mods for my vehicle.

I had the dreaded hesitation, and I ran my gas down to empty and filled up with 93 octane. then I put techtron fuel injector cleaner in, used a 1/4 tank. That's when I did my gotts mod, but I did reset the pcm and took the truck for a drive at all speeds within 15 minutes of the reset. No hesitation after that. Good luck!

I had the same problem on my 08 Limited 5.4 when I bought it 2 months ago. Here's what I did to fix the problem. Turn the key to the on position but DON'T start the engine. Now press the gas peddle to the floor SLOWLY and let it come up/back as fast as you can, turn key to the off position. Now do this two more times. Now start the engine and go for a test drive then report back here with your findings!
This procedure works on my motorcycle so I tried it on my truck and it worked there too!
I also disconnected my battery but that was a couple of days later and wasn't done to correct the throttle problem but it drives like it's suppose to now.
