Missing Prestone? uh... What? I'm not sure I understand what you're getting at either.

From: Cincinnati, Ohio - Amelia is the exact place. There is no one else on this site from where I am. Seems like everyone is from Cali or Washington. I guess I need to move.

Funny mine is doing the same thing this morning, and I noticed that once warmed up my heat was gone. If your low on coolant, causing the IACV to not get enough can it cause an idle pulse pretty much on a one second interval up and down? I haven’t checked the coolant yet, as I just fired this thing up for the first time in a week.
