Ralph,
Go to Ecudoctors dot com and look at their diagnostic video and troubleshooting section on 911's.
Could be your ECU is shot.

Good news for you is ECU Doctors are in Miami area.Great peeps. They have a very good exchange program.

Last year- turned off my 84 Targa about 30 minutes from home. Had to ride back home on flatbed.After replacing ECU relay and checking sensors.....determined ECU was shot. Got rebuilt from Jorge at Ecu drs and car fired up immediately. Also idled and ran better!

Getting 20 yrs out of original is ahead of the game. BTW-Go for the 87 box. It has bigger chip and more memory.

Good luck
JTT
