Flashing Check Engine Light - No Trouble Code
'02 bought in '05 4.3L 6cyl 97k mi
A year or so ago, the Check Engine started flashing when I wound it up to 3000 rpm and at about 90 mph for about 20-30 seconds. I slowed and the flashing light went out. Ran OK.
Yesterday, uphill, against the wind at about 2600 2800 rpm and 75 mph it happened again, I slowed and the light went out. Ran at 75 mph no problem
Both times, I scanned and found no trouble codes. The truck ran fine and runs fine now.
Any ideas / suggestions? Thanks.
