Unusual problem

[bigredstx]

My truck has been doing crazy stuff lately. Im really not sure how to describe it but when i go to slow down and come to a stop it was shut off. Its also idles erratically sometimes. I just bought a fuel filter and im going to change it but do you guys have any other ideas? its a 2006 4.6 with 97k miles

Might check fuel pressure

Mine has done that twice.... About 18 mo apart

First time I took an hour drive then turned into a business for an Interview and soon as I turned into the parking lot it died... Fired right back up and drove on..


2nd time I was pulling into a DQ and soon as I turned it died.. Fired right back up and hasn't done it since..


But every now and then when I would slow down at a red light it would feel like the rpm's dip really low and the truck feel like it shut off.. but it never would..


I never did figure out the problem. I thought it was VMP's tune, but he sent me over a new one and it never happened again.. but Not sure if that actually fixed it.

But I would replace fuel filter, clean throttle body and MAF, and air filter and see if that helps..

Dirty throttle body maybe?

it is trying to be a hybrid

Put gas in your tank, sounds like your are low on fuel.




The fuel filter is a good start if it has not been changed lately.

My 2006 F150 went through similar issues at around 90K. I had a CEL intermittently. I had 2 bad coil packs, and needed the dreaded spark plug change.

Was all good after that.

THIS!

My buddy just had the same problem with his @ 70,000miles he said it was 2 bad coil packs then he did the spark plug change just in case his is a 07
