99 Suburban part deux.
I only had a minute today so I just tried to start it normally. Fired right up and idled right down. I think it's messing with me. Next step...codes.
It couldn't just be the Sea Foam that fixed it, could it? It was still seriously messed up just yesterday. Regardless, I don't trust it yet.
Give your head a shake! That stuff is PFM!
And stay away from ethanol.
