Stallilng problem with my 99
Well I have been trying to trouble shoot a problem my 99 f-350 PSD has been giving me for a few weeks. When I coast a long ways to a stop and this is intermitent, it will loose power and then the closer I get to the stop sign it will just die. I can put it in Neutral and fire it back up on the move and it will usually drive off just like usual. Sometimes however it feels like it is lacking power like it just cant get going and it will shift hard like the timing is all screwed up.
Here is what I have done
Fuel filter less than 1000 miles ago.
CPS replaced the gray one with another gray one a week ago.
Replaced the alternator last week. My battery light was coming on so I had the alternator checked and it was bad, so replaced.
Made sure all my fueses under the hood and the in the cab box were all good and operating.
I just recently purchased the truck a few months ago. It has 101800 miles on it. Also has an Edge chip that the previous owner said adds 85HP and 150lbs of torque.
Any help would be greatly appriciated! Im at a loss at this point!
Thank you guys!
