1988 Century stalling problem

  • 1988 BUICK CENTURY
I have an Buick Century, 1988, 102,000, V6 (not sure exactly which L type though). It stalls intermittently at a stop, in idle, or even sometimes when driving, and the check engine light is perpetually on. Just had it serviced, they cleaned the MAF, and replaced the computer module, and it ran nicely for about a half hour. When started up later, it returned to the exact behavior; when first started up, it stalls, and takes several tries sometimes, then runs rough in idle, and dies again. If this helps at all, one of the fuses (the one that runs the dome light, radio, horn, and power lock) has a short, and since these are non-essentials, I haven't had a fuse in place for several months. So I wonder if there are additional shorts causing problems to the computer module? How difficult are shorts to fix?

Unbolt the fusebox from the firewall and have a look. Take negative cable off first!

Sounds as if you may have a fuel pressure problem or you IAC (Idle Air Control) motor is dirty or sticking. Change your fuel filter first. If the fuel pump is 'loud', it's probably on it's way out. As for the IAC, unplug it, unscrew it from the air induction unit and clean it and the air passage way it screws into.
