Your Ride: 1998 328 IS
Cold Start Question
My first posting on the board. I think this is a great website, and it helped me a lot when searching and negotiating for a BMW.
Anyway, I have purchased my first bimmer. A 1998 328ISC 5 Speed with 34,000 miles on it. The car runs 100% perfect.
The last 3 mornings the temperature was below 40. when I start the car, the rpms bounces between 1400 - 1500 3 times, all within 5-8 seconds, then goes down to 1000. Is this normal on these cars? If not, has anyone else ever experienced this?
Any advice would greatly be appreciated.
Sounds like a little moisture/condensation in tank - get yourself a bottle of STP gas treatment (you could treat it to injector cleaner which is just more concentrated) but the $1.29 stuff with at least 10 gals will help that. Also is all maintenance up to date, old plugs will do that too.
