:)<BR>***********************************<BR><BR>O, boy, what a
mess!<BR><BR>Car started fine this morning but idled very roughly when cold. I
made a note to myself to adjust idle and timing after work in case changing
the AAR adjustment threw off the idle speed. I figured that was possible
depending on where the AAR was set when I last did the idle. <BR><BR>After
getting off the highway on the way to work, the motor stalled every time I
took my foot off the gas but for one time when the idle stayed steady. After
work, it took five tries to start the car. Very unusual as it always starts on
the first or second try. I pulled out of the parking lot and stalled. I then
proceeded to stall every single time I let my foot off the gas but it drove
perfectly well on the highway. I got close to home and stalled at a light.
This time it wouldn’t start. It caught on one or two occasions but wouldn’t
fully fire up. Then, it’d crank and crank but nothing else. Of course it
started pouring rain after a few minutes…..<BR><BR>Anyway, I checked the
following partly by myself and partly once Jessica showed up (the benefit of
breaking down only 2 miles from home)…the list isn’t in sequence:<BR><BR>—fuel
pump relay clicked and pump primed when key was turned<BR>—FI power relay
clicked when key was turned<BR>—MPS sensor plug wasn’t loose<BR>—all injector
plugs were secure<BR>—trigger points connector was secure<BR>—injector grounds
and ECU ground at case center line all secure<BR>—wires to generator were
secure<BR>—12V to black/white wires from FI ground to T2 connector and 12V
from T2 connector to ECU<BR>—resistance of both temp sensors was
fine<BR>—dwell was ok and everything in the distributor looked fine<BR>—12V to
coil<BR>—took out the ECU and verified that the plug wasn’t loose<BR><BR>It
was pouring out and I was staring at the ECU laying there in the cargo area
and decided to take the plunge b/c Jessica showed up with one of our spare
ECU’s. I plugged it in and the motor fired right up. Just to confirm I wasn’t
hallucinating, I tried the ECU I had just removed. No start. Tried pressing on
the harness in case it was loose on the card edge. No start. Put in the spare
ECU and it fired right up again and I drove home without any
problems!!<BR><BR>So all along my "intermittent warm idle lope" was the ECU
taking a dump until it finally died?!?! Is that even a
thing??</FONT></BLOCKQUOTE>

face=Arial>Well, I don't know if it's a sign of a dieing ECU, but it certainly
sounds like it's possible. At least having a spare ECU to put in and get the
home helped. I guess you'd have to try the replacement ECU for a couple of days
to know for sure.<BR>
