I don't have a tach in the truck or on my light but it was hunting in a range of around 200-300 RPM. Rough idle and rich condition (bad MPG plus high CO and high HC on the previous smog test) being consistent with a bad ECM.

No name rebuilder with a "born on" date inspired by those old beer ads. Doesn't look too promising. I googled the number and one of the first hits was a DSM guy complaining about shoddy work this guy did.
Oh no. I'm voiding the warranty.

Opened it up and found globs of solder everywhere.

Capacitor ooze and burn marks left on the board. I'm not an electronics expert but this looks like crap to me.
I don't know what it is about Florida and ECM rebuilding. It's a cottage industry there. I ordered an A1 Cardone rebuilt one off Rock Auto with a core charge instead of hassling with send-in-to-repair.
Do you have a part number for the temp sensor that hooks into the ECM? Can't see it on the fiche or Rock Auto.
