I've got an '87 chevy truck, 5.7L TBI, 700R4. It has pretty low mileage on it, only 57k.
I've noticed that when I'm idling and I shift gears, such as P to D or P to R,
it tends to stall on me. Having the steering wheel turned exacerbates the problem also.
The truck seems to do fine at highway speeds, it's only at idle speed.
I've asked around on a few diagnostic websites and have heard all sorts of things
from "It's your IAC sensor" to "Its your fuel pump..."
Has anyone else encountered this problem before on the same or similar truck?
I have replaced the fuel pump, IAC, TPS, MAP sensor, and fuel injectors...all to no avail.
The symptoms of my truck are that when I shift from P to D or P to R, the engine stalls...
and when I turn the steering wheel it tends to exacerbate the problem.
But it only does it at idle speed...Sound familiar?
For instance, when I'm sitting at a stop light and turn the steering wheel to go, it stalls...
or when I'm backing out of the drive way, and shift from R to D (especially with steering wheel turned) it stalls.
But it seems to do OK at highway speeds--it just has idle issues.
I spoke with a GM mechanic who, coincidentally, had worked on a bunch of '87 Chevy's
that all had the same problem from the factory...the distributor.
I have not tried this yet, as a new distributor could run me $120+.
I'm wondering if you've tried this at all, or had someone make a similar suggestion.
