Dude, I 'm not trying to say you can't fix it, by all means give it a shot...I am saying though it might be worth the 1 hour of Diag that most dealers will charge to get the info you need to get it fixed...most of the codes are probably being set by the failure of one part, not just sensors failing all over the place or the PCM taking a dump, and more than likely you need the IDS or something similar to sort out what the actual root cause of the problem is.

You don't have an Injector driver module BTW, the 1298 is bogus.....trust me take it to the dealer and get the diag and see what they recommend, then fix it yourself....
