Occasional Dead Pedal

[Cowboy]

Hi all,I'm having this problem with a 99, 5 speed, fairly stock, ~25,000 miles on new injector pump , little bullydog 'chip' and BHAF. I'll be going down the road normal, and suddenly I'll loose all power, it just wants to idle. Now if I hit the clutch, and let the fuel pedal all the way out, then push it all the way back in, and let it all the way out again, it's fixed, and I have power again. and when it has this problem the check engine light turns on and stay on for about 30 minutes. I understand checking for codes would be very helpful, a friend of a friend may have a code checker I can use but I'm not sure. Is there something I can do with the key to check for codes?thank you for the help.

On a '99, you need to have a reader. No key trick.I'm 99.9% sure P0121 will pop up; I'm having the exact same issue. Replace your APPS with a Timbo APPS.

What kind of fuel pressure are you seeing? Idle and wot. I went thru the same thing and fixing my lift pump situation cleared it up. When it happened to mine i would have to restart the engine and it would work like normal until it happened again. Get the codes read and it will help a lot.

Definitely need to get your codes read, then post them up.

APPS sensor fail that causes dead pedal willl 99% of the time set a P0121, P0122 or P0123 error code. The other dead pedal that doesn't set codes is either VP44 failure or ECM failure (rare). So please read your code and report back.

I am having the exact same issues and i have these codesp0753p0713p0720p1763p1765p1693I noticed something though that may make this information invalid. The odometer is not showing me niether p ecm or p pcu and i am not getting to p done messages. So something weird is going on.
