this just started yesterday my truck is missing,idles fast then comes close to stalling or will stall if you get it to the point you can drive it the motor will rev way up then die right out my main concern is this every time i put my code reader on it i get a different code tried to start it 4 times in the last 12 hrs and each time a different code came up the codes are P1151/P1633/P1285 i also had 2 other codes 1 said it was over heating but it wasnt the truck has always been very reliable never any problems it has a Triton V8 4.6 i think or 4.8 cant remember but it is the small 8 (289) could it be my computer

 

I'm gonna say you have a wire that has a break or rub. Follow the O2 sensor wire on the driver side and look for damage.

 

Thanks for your feed back but now its not showing any codes at all still acting up and stalling but no error codes at all
