so glad i found the forum its been a bit of a help before for minor stuff.

My problem now is this, just started today, its been hovering around 0 F for the past few days and my 99 takes a bit to start but then runs fine. Today she started up but it was a very slow chugging for a few seconds, then she evened out. During normal driving it runs quite well and is responsive, the oil pressure remains quite constant just above 40. Is this something i should be concerned about or is it just the extreme cold?

I think its the cold. Depending on what type of "slow chugging" your experiencing it might be something different. I think I read on here that the extreme cold does something to the transmission fluid and it takes a little longer to "get to the right place" (so to speak) which could make the car seem to chug. At least thats what happens to mine when I am first leaving work at night and in the morning. It seems like it takes more gas to get to the same speed when its very cold. After a few mins its usually fine.

First off, welcome to BonnevilleClub

Midland huh?? That wouldn't be Midland Michigan would it? If so, I am only about ten minutes from you


As far as the cold start problem, can you go into more detail on it? Does it roll over slowly then start and run fine?

When was the last time a tune up was done on it?

My car starts pretty slow in near/sub zero temps. But once it gets going, it'* fine. The cold is the problem I would guess.

it had a pretty complete tune up last spring or so, new belts, plugs, wires, fluids, new mass air flow sensor in october, bout the only hard parts it really needs is struts. It just turned over 134k. As far as the chugging, the best I can describe it is just sounding like very low rpms, feels like the car is very slightly pitching to the left and right, and i mean very slightly. Like i say it evens out within a few seconds, it did not do it when i left from work not 30 minutes ago, so it could have just been a fluke, but if it may be something i need to take care of soon i will seek advise from my regular mechanic.

and yes it is midland michigan.

yeah, im in Fort Wayne Indiana and when it drops below 10 here, usally once a week, it almost does the same thing only starts a little quicker than you say. Pretty much almost any of my vehicles do this except for the 2008 yukon....its garaged

Yeah, it has been VERY cold here recently....

Neither one of our Bonnevilles really like to start up "normal" in the cold. I don't fire up the '03 much, cause that is Steph'* car, but I know that my '93 is a little hesitant to start up sometimes when below zero.

How did you find BonnevilleClub?
