Why would your 1996 Eclipse stall when you slow down to idle speed then the problem goes away and it runs great for a fiew minutes or sometimes hours?
Could be a sign of your fuel pump about to go out. I would start
by getting the injectors professionally cleaned (I don't mean that
cheap bottled crap they sell at the parts store). If the problem
persists, have your fuel pump pressure checked.
My 96 Eclipse has the exact same problem and it needs a new
computer module. I did everything else possible for it and that's
the only thing left. They're kind-of hard to find because
apparently they tend to die a lot on this kind of car. Go ahead and
try cleaning the fuel injectors, but it did nothing for me.
I'm dealing with the same problem with intermittent car dying
and checked the wiring for shorts, checked all connections, battery
and alt working properly. I think I have 3 problems actually. I
believe the vapor/liquid separator is bad allowing fuel into the
vapor line if I fill tank past halfway. My radiator has a leak and
I'm suspicious it may be clogged and not cooling properly but
sometime the car cuts off before the engine warms up or within a
mile which I think is either the computer is shorting out or maybe
an air sensor. Possibly coil When it dies it takes a few minutes
before it will start up. When I turn key to on and the dash lights
come on, if the check engine light doesn't momentarily come on I
know it wont start. I see it I know it will. I checked for 12v on
the coil pack power wire and when it shuts down and not immediately
start there's no volts. I wait a few and then suddenly 12v again
and will start. So the ASD relay might be going out or something is
telling it to cut power. I'm at a loss really. I did clean out the
throttle body and installed a new CAS and worked fine until I got
more gas earlier and then stalls on way home after stopping kinda
fast (separator valve) but even after I got it home it will idle
for a number of minutes and simply die each time if at normal temp
gauge reading or cooled off. So maybe not radiator. I keep topped
off constantly. It's like something is just turning the power off.
Going now to clean the IAC, MAF, TPS and throttle body and plate.
Good luck to you and hopefully that gives you some ideas.
