Evolution problems

[mothership]

need help guys my buddy put an evo on his truck and it throws p1280. he has it set on extreme setting and if you let it sit and idle after about 3 mins it will just shut down but it starts right back up and then when he drives it it idles rough when he come down to an idle at a stop and sometimes it cuts out but it does not do it every time. whats goin on .????
im thinkin he has a bad sensor or a weak sensor i just dont know which one

Here is the code--- P1280 ICP Circuit Out of Range Low

It could mean the ICP sensor is going out or it could also mean the HPOP cant keep up with what the EVO is calling for. Also the IPR might be bad as well. Have you tried a lower program? Try that and see what you come up with.
