[QUOTE="Denver_FJR, post: 911557, member: 19217"] Some updates... Replaced air filter and did TBS. No better. Borrowed an infrared thermometer... inner header pipes are running about 300°, while outer pipes are about 250°. Is this significant? I had done a BJM mod many months back, bumping each cylinder up about 5 pts. Frankly I never noticed a difference and during the summer reverted back to factory settings. The thought of trying to second guess the factory settings without actually measuring exhaust didn't sit well with me. I'm running through the FI troubleshooting section of the FSM. The test for the "pressure difference" (diagnostic code 3, p8-73) says to set engine to run, press starter and watch for change in readout. When I hit starter the engine starts and rather then see the pressure readout change, I'm getting code "ER-1" displayed on dash. "ER-1" indicates "No signals from ECU". Engine does run, so hard to believe this is valid code. There are no codes stored otherwise. [/QUOTE]
