[Kylem]

I have a 2005 eb v8 expedition there is hesitation when going forward changed the throttle position sensor and the tps error went away going to change out the throttle body motor next cause after I pump the gas it will start going and I noticed while pumping the gas with the key turned to on the throttle motor sorta wines anyone got any ideas

I to have an 05 expy that had similar issues. First does it hesitate or cut out when driving.

If it cuts out when driving you may need to replace plugs.

Hesitation I had to replace the throttle body they go out. Also I had one mystery issue the wiring harness lead to the MAF had a partially broken wire when I took it off to clean the throttle body it completely broke. When fixed the truck ran worse until I replaced the Throttle body now runs great.

Hope this helps

I had some old plugs (100K+ miles) that lead to hesitation... Replacing all 8 fixed it and did a good job on bringing back throttle response off idle.

How many miles on the truck?

How many miles on the Spark Plugs?

What was the old code that popped for the throttle body issues?
