Alert me when someone posts in this thread:

I think Simon sent you in the right direction regarding the AMM, although the ECU in general can be trouble in your particular year. That usually manifests itself with a car that won't run the fuel pump, but I've seen them fail in other ways too.

The easiest way to check components is to replace them with other ones. Most of us have a cache of spares. If you need a spare AMM or ECU to try, send me an email.

Before you go digging in, I would spend some time making sure you don't have a vacuum leak somewhere. Its nice to solve problems with a couple feet of new vacuum hose.

Good luck!
