Do you have a chip or are you tuned up?

[dukey_78]

nope bone stock rite now but will do same with programmer

[vitalidle]

Yeah its the 1211 code right? That usually means your hpop can't keep up with the oil demands for your injectors. Usually that happens when you chip it. Hopefully someone smarter then me will chime in.

it has no chip in it now when it does it

Here is some info for ya:

DTC P1211 indicates that injection control pressure was above or below commanded desired pressure during self test mode.
Possible causes:
incorrect oil or viscosity
poor oil quality
gel fuel/no fuel
low fuel pressure
damaged IPR valve
high-pressure oil system leak
damaged high-pressure oil pump
damaged PCM
Verify correct oil quality/viscosity and correct fuel grade are being used for the temperature conditions.

mine was doing the same thing at around 50,000 and it ended up being the tranny speed sensor. Hope this can help you.
