Engine Misfire......NO DIC Codes
So my 97 C5 was sitting for the last 10 weeks with low fuel, at which point the wonderful GM sht seats shorted and drained my battery. Replaced the battery, car started right up and ran perfect.
I took the car to Sunoco and put about 8 gallons in, and 1 cup of Seafoam to clean out the bad gas. Car ran fine.
Drove around, on the highway, then used 1 gallon of 100 octane (which I use frequently)
After the race fuel, I drove another 20 miles, then parked it for an hour.
I return, and the car feels weird, jolting on acceleration. I hit 50mph and Check Engine lights starts to flash....yet the car is pulling hard.
I drove the car another 50 miles, filled up the tank from a different Sunoco station, yet the car still seems to misfire and flash the CEL above 40pmh.
I do have LS1 edit on the computer, so I'm not sure if I need a reflash or something. Most importantly, I have NO DIC codes at all.
