i can't read the sticker on the side of the door to find out how much tire pressure i need for my tires, i have hankook 245/75r16's on and i need to inflate them but not sure how much too. Also when i decelerate with the 4x4's on, i get a vibration from the front, this vibration doesn't happen with the 4x4's off. i have a code that says the spark ignition module is not functioning properly, how do i fix that, my mech says its intergrated with the computer and he's wondering why the truck and vin says its a 95, but it has a 96-2000 wiring harness on it. that spark thing is why i have the check engine light on all the time, the engine is rebuilt and newly installed, its a 305 5 litre. and last thing, my climate control dial doesn't work properly, i only have floor heat adn a lil bit of panel heat coming out but zero defrost, how can i fix this? do i need to replace the climate control box???

thanks for your input,
