Hey there, "Mods" and all who've taken any interest in my journey. Took a number of days off, after replacing those check valves. Real gnarly in the tubes and connections, much better, now. OK, seems I have not had a repeat of the P0400 code. That's good, but, back to that nasty P0300, again. One thing I don't believe I mentioned, before, when I plug any scanner into the data link terminal, after a few minutes, key on engine not running, battery goes dead! In the two years I've been dealing with this car, never happened before! What tha hay????.......Secondly, no rev limiter or rev cutoff at all! Stomp on it and the tach justs keeps going, Always heave to back it off, just before redline. Which leaves be to believe that someone was in the ecu, playin' with a tune. Any and all input/ feedback, most appreciated! Enjoy the bday, if and when you can! Regards 2 all

 

Possible dead short somewhere, check your battery cables along where the Starter lead runs, and your alternator lead, on my truck the motor is sitting a touch low and the smog valve pipe was sitting ontop of the starter lead and was damn close to deadshorting the battery to the block. check voltage draw at the battery terminals when the truck is off after its sat for about an hour. and this ties back into the rats/pests issues with them eating wires, check your connections everywhere, inside and out.

 

I'm on it! THX 4 the help!
