i have an 88 caprice which origanally came with the 4.3 tbi. i swapped it out and put a slightly modified 350 in it. before i did this my air and heat was working fine, but now it doesnt even come on when i flip the switch. the only thing i can remember thati did was take out the computer on the passengers side kick panel. was this the wrong thing to do or what? in need of help fast. its kinda hot in memphis now.
