Ok. I have a 1995 caprice, I've had issues with the car hard starting.and when I do get it to start the car pops and backfires. But once I get the car going things are fine. I put an OBD1 tool on the car and got 3codes: 18, 32, 36. What are these codes and. What do I need to do to fix the issues...I was doing highway driving and the car cut off. VERY SCary!!
