i have a 2001 ford f150 with a 5.4 and i put a superchips tuner in the truck finally. everything was going good then one day i tried started noticing spark knock in my truck...then a few days later i started it and it would not idle...it'd start up then when it came down to idle at the normal 700 rpms it'd stall...i could rev the truck up and it'd run at high rpms but once i let off the pedal it wouldn't stay running. i deinstalled the tuner and it was fine....then yesterday it did the same thing. i have owned the truck for 5 years and its never done this. anyone have any ideas? Thanks

 

The truck had the same problem AFTER uninstalling the tuning from the programmer?

If it is,..... your truck is the problem not the tuner.

 

but it's never did this until i installed the tuner. so could it have messed up my truck?

 

Sounds like it was just random timing and it's your truck.

 

Return to stock and then tell us what happened.

 

I asked the Q,.....no answer.

 

Call Mike Schimmack @ Superchips, this is his direct number 407-585-7097 or mschimmack@superchips.com .

 

it has done it since i have returned to stock.


so im wondering if its just an odd occurance or someone suggested it messed with the computer in my truck.
