Hello,
My 1991 sometimes stalls when the temp. reaches 92 plus.
Today it was only in the low 70's and she stalled on me.
She acts like she is out of fuel.

I pulled over and switched out the fuel relay (which was
hot) and that did not help. Then a few mintues later she
started up and drove for about 2 minutes, then stalled
again. I decided to pull the ECU down because she felt hot
too. This is when I realized that I have the pink label
561 ECU in this car. A couple of minutes later she started
up and drove another two minutes or so, then she stalled
again in the Target parking lot. After shopping (about 20
minutes) she started right up and I drove home without any
problem (ten minute drive). The ECU was still pulled down
and had cooled down.

I am guessing that my first move should be to replace the
ECU. I have a couple backups in the attic, but can't get up
there until the kids are asleep. I hope they are 951, 935 or
933 model ECU.

Last year I thought the stalling was because of the Ethanol
in our gas because she only stalled at 92 degrees and above.
Today when she stalled and it was only 70 degrees.

Any advice would be appreciated.
