2001 3.4 intermittent rough idle and bogging

Hello everyone.. Last fall I started a post for a hesitation issue my truck's having.. I haven't figured it out and its actually gotten worse.

At first it was just a slight hesitation when it was cold out and the engine was cold. In the hunt for this I either have a new problem or this one getting worse. It may be coincidence but after I ran some High octane and a bottle of techron I started getting a really rough idle and it would occasionally fall on its face accelerating.

In order Ive replaced the fuel filter, plugs, wires, removed and cleaned the Iac, cleaned and now replaced the MAF and just put new coil packs on today.. No improvement and no codes.

After getting the coil packs in today I took it on the highway several exits.. was driving fine for several exits then on the way back it started to bog and fall on its face again.. at like 2500 rpm in 4 gear... 3/4 throttle and wouldnt accelerate.. finally would come back and allow me to go on.

Any ideas?

TPS? Coolant temp sensor?

 

Can I have bad fuel even though Ive filled it at least 6 times since the first time its happened? Ive run several bottles of heet in it too..

 

Ok well this has reared it head again...

Its 60 degrees out. I just stopped at the store and when I left the store on the way home it started to bog and wouldnt rev. Any suggestions on what it can be Im thinking its the IAC again.

 

got suck at another light.. Truck wouldnt rev and would just backfire when throttle given.. Anybody experience this?

 

any suggestions on how to get help with this?
