I have a 2000 f150 4.6 my current issue is it runs great in park,reverse and neutral but drive spits and sputter and dies .......I'm thinking it's some sensor but not sure what controls what.

Do you have any codes? Sounds more like an electrical issue like plugs, COP's. Engines will often run well at idle or with no load on them then start missing when you put them in gear.

No codes that I see but my battery froze so I'm going to change and let it run to hopefully get some clue

mjstutter12

ok no codes but issue is still there
any ideas on what it could be i know there is around a dozen sensors but it does fine in reverse no issues only drive

If it runs fine under load in reverse more than likely it not a engine problem.

I'm wondering if it's mabey a linkage issue do not know much about fords system

It is real hard to tell what is wrong without listening to the truck, knowing the maintenance history on the truck, and inspecting it. It is not for certain, but the condition of your transmission fluid might give a clue. If it is dark red or black, this is not good. It is really not good if it is brown and smells like it is burnt. Have you kept up with maintenance like changing filters, PCV valve, cleaning the MAF sensor, change your spark plugs? Has anything happened to the truck recently to create the problem. Like doing a lot of off roading? When did the problem first start?

All of this could give you a better idea as to what the problem is.

It almost sounds like iac sensor I know when they go completely bad the truck will start up but when u put it n gear it will die just a idea

This is a dealer maintained baby with full service history but my local ford dealer is kind of shifty ....This happened on the e way out of nowhere ...this same sort of issue happened b4 but it had issues in reverse too bad coil

Ok iv done some digging and got 3 codes 2 for o2 sensors and one for Vss error o2 are only 1000 miles old mabey one but not both but this Voss code might need some checking is there a way to test
