Well here we are a month and a half later, and I never did take it to the shop, and on our way back from Pismo this weekend the light came on again. I was towing again, and just getting up to speed before shifting into 4th gear at about 55 mph, and it lit up. Then, later on after we got home, it wouldn't start up again until I tapped the accelerator pedal. Three starts later it went out and it hasn't been back on in the last couple days. Hubby thinks the fuel pump has been making a weird noise lately, too, for whatever that's worth. Anyway... I'm taking it in to the dealer in the morning. Stay tuned!
