Hi, new member here. I have a 99 Firebird with a 3.8l and automatic transmission. I was coming home from work and the car just died on the highway. My initial guess was that the fuel pump had given up the ghost. A couple days later, I tried to start the car in the driveway after pulling the codes. The only thing that came up was p1518.
The car started fine and I drove it around a little and all seemed fine, so I deleted the code. The next day, the car started and idled, I gunned the accelerator a bit and it sputtered and died. Now cranks but will not start. New codes are p1516,p1221, p1220 and p1120.
I am now guessing that the throttle body is no longer responding to input. Would that be a fair presumption? Can these fly-by-wire TBS be rebuilt or am I looking for a replacement?
