It is starting to get a bit chilly up here and I was wondering how long I should technically let the car warm-up before driving? I am sure that there is a recommended lenghts of time and an actually lenght of time that people are doing it. So, lets hear it...how long?

last night, i took it very easy (shifted slowly, shifted at 3000rpm, kept revs below that) and the engine actually ran quieter and better i thought.

Just an aside on winter warm-ups, since you're new to the NW and all, it is a risky venture to leave a car idling while you step inside to get your coffee. Local tweakers (meth addicts) cruise the neighborhoods looking for running cars with no owners. They steal the cars and use them as a cooking spot (and you don't want it back) or just for joyride and/or sale.

Interesting about not warming it up, i didnt know that. I have been letting it warm for about 2-3 minutes in the morning and it seems to be good after that. What is strange is if I go for a drive again after its warm (just start it and go) it seems to drive like crap. I pull it out and stop, the idle goes down to about 500. Whats the deal?

the heads cool off, so when you start it after the initial warm up (visit to store for example) the CHT reistance goes way up to around the cold spec. When you start your car, the ECU thinks the engine is cold for a couple of minutes, while the heads warm back up again (~350F). |
