This topic has come up before but I can't find resolution please help
After truck has been running for about 10 min and gets warm I get irratic revs won't rev up struggles to start I have changed fuel pump today to try and cure this fault with no luck I am thinking maybe a relay or something getting warm but don't have a clue it also smokes alot when eml on fault codes are
Boost pressure sensor 12
Ne sensor sub 18

I tried to clear the faults but I am now getting the following
Ecu internal error present 00 this will not clear
