So I just blew up your DM inbox with the diagnostic charts for all the codes you have. That should get you moving down the path to diagnosing them.got a new set of dump hinges ordered for the flatbed swap out . the ones in there have some egged out holes so figure time for new .
called local tire shop and its about 30.00 each wheel for steel shot blast and powder coat my choice of color on the rims . so when i do new tires and rims there getting cleaned and painted . thinking a grey is as close to stock as i need to go . there silver is more powder coat chrome than silver . so i picked the grey to be same .
read the codes for the check engine light and got p0704 clutch switch / p1518 tac mod problem / p1125 gas pedal problem / p0154 b2s1 o2 sensor problem . need to look in to these . the o2 i think is the source of my leak i here up frontish . @ZooMad75 @Larry
and the 95's 1 airbag blew off so a wheel swap is in order but easy to do .
and if it works i will get a bonus of ............... A/C in the truck
