well this has been happening a lot lately. I'll be going to accelerate and it feels like its fine then it starts to feel like its pulling back. Happens at all different times weather its cruising or accelerating. I put it in 2nd gear to see if it would do it there to and it does.

I've already changed the plugs,cops and fuel filter. Any advice? 07 4.6L

 

Clean the maf and tb......the how to section of the forum has articles on these procedures....

 

alrighty im not that engine smart so where exactly is the MAF. I know the TB.

 

Mass Air Flow sensor. Usually located on the air intake. Measures how much air is coming in the intake, temp, barometric pressure.

 

If after the MAF and TB cleaning. next comes a new fuel filter. If that still does not fix it, it will most likely be a bad COP(s) [Coil On Plug].

But do what 88 said first.

 

ok i just picked up some cleaner for both. I'll tackle this tomorrow morning.

If this still occurs, what next? I've already replaced all 8 cops and plugs, fuel filter and air filter.

Did this problem occur anytime AFTER you replaced the COPs?

How many miles? any CEL? (codes)

 

well i was getting a misfire so i replaced the plugs. Still kept getting a misfire and replaced the cops. Fixed the misfire. changed the air filter and fuel filter due to regular maintenance. All the while it was doing this even before i changed everything. So at first I figured it was possible the misfire that was doing it but after i fixed it it still kept doing it. So hopefully when I clean the MAF and TB tomorrow it will stop.

 

No more codes are being thrown after I fixed the misfire with new plugs and cops.
