2000 f350 crewcab 4x4 7.3 auto.I picked this truck up a couple weeks ago.Runs and drives great.
Last couple days I'll be driving,on the throttle,and nothing.Engine does'nt die,it just drops down to idle but no throttle response.If I put it in nuetral and back to drive all is fine.
Previous owner had this happen a while back.I guess they had a performance chip.The truck was doing what I described and they took it to their mechanic.He ended up changing the throttle cable or ??? Still did it.Then they figured it was the chip so they pulled it out.Supposedly that fixed it.Till my situation.

Anyone have some credible input.Thanks

Tps maybe?

I think so too.Previous owner said they replaced it???I guess i'll start there.
Any input on how to test the tps?
Any other ideas.

Have a read through this, it might explain why moving the shifter into N fixes it (might as well take the column apart and have a look, it's such a common problem - with a "Free" fix to boot!).

I always forget about that one. I fixed it on my truck, but the only issue it was causing me was the inability to turn off OD.
