Hey, folks:

I am new to this formum and dealing with fuel-injected engines.

I have a 1990 Chevy S-10--4.3l, manual trans, 6-cylinder, fuel-injected--that starts fine, runs fine. But when I let it idle, it invariably idles down before dying on me.

Where do I begin solving this problem with a fuel-injected system?

Thanks for any suggestions.

Thanks for the response, Will2. But my bad. I should have indicated I had already completed these suggested parts switch-outs--and it still misses.

Have also changed spark plugs and wires.

Possibly a bad injector.
