i recently installed a injection and supply pump worked good for about a week now truck wont go over 2500 rpms in neutral it gives me the code 0222 idle validation signal low. What does this mean? i think the problem is sumthn electrical but idk. Thanks for the help

 

this started when i pulled away from a stop sign the check engine light was on until now and it went off after i lost power. i have 1693,0122,0216,0234. i never had the codes cleared after i replaced the injection pump. some one please give me som idea as what may be wrong

 

Most of them are related to the injection pump.
Clear the codes and report back.
