"15000 mile update"
Well another summer has come and gone and I still have not installed my McCullough supercharger. I'm having too much fun driving it. Oh well, maybe this winter.
One of the objectives when we began this project was to use OEM components as much as possible for reliability ease of finding replacements. This strategy proved worhwhile about a month ago when the engine suddenly started missing and backfiring through the exhaust. The truck could hardly keep moving so I turned off all the accessories trying to coax it home. When I turned off the AC it instantly started running fine. It continued to run great even when I turned the AC back on. Over the next few days it started acting up more and more. The only way to get running properly was to turn off the AC and/or kill the engine and restart it. I could not think of any reason the AC system would cause this so I checked the fuel pressure, ignition timing, and electical system. Everything checked out fine. Even though there was no service engine light or codes set I started to suspect the ECM. Since the unit I was using was an Ebay special and I could hear some strange clicking sounds from it I decided to replace it. So I removed it from the truck and pulled my chip out and headed to Orielly's. Well for $59 exchange I had a reconditioned unit and all is well.
Thanks,
Ron
