so I'm having a problem with my 87 2.8, the car stalls whenever I pull up to stop lightsand things for more than about 15 seconds. It also frequently stalls out when I put it in reverse. Now I've replaced the idle air controller and hooked it up to a scanner and it wasn't throwing any codes. Any ideas? This problem is getting really annoying...

 

When's the last time a tune up was done?

Have you checked the fuel pressure?

 

It got a tune up about 7k miles ago. The scanner said fuel pressure was good but how do you check?

 

Hey, it might be possible that you have to relearn the idle. I've had to do it once or twice on my 3.1 (replaced IAC/battery). Some say it isn't needed, some say it helps. Either way, it couldn't hurt so here's the link I've found:

I don't know how many times now I've said this... THERE IS NO IDLE RELEARN ON A 2.8, PERIOD. Except FWD vehicles after 1986 and maybe 1989 F-bodies (don't know about the 89 ECM or the S10 after 1990).

OP, check for vacuum leaks. If the vacuum hoses are original, they're probably degraded to powder. Replace them all after checking with fingers to see if they have deteriorated. And get a fuel pressure gauge. There is NO WAY a scanner would know the fuel pressure at the fuel rail.
