Frigid weather: Engine stalls under load at startup Sign In

Hi,
My car:
Volvo S70 T-5 (stock turbo)
1998 model year (1997 in-service date)
155,000 miles
Automatic transmission
I only use supreme octane exclusively (the car comes with a factory equipped Turbo)
Factory recommended service always followed very precisely.

On cold morning (ambient temperature is btw 0 deg F to minus 13 deg F), and I start my car, I let the engine free idle for 30 seconds for oil circulation. After this period, as I gently shifted into "D", it resulted, on some occasions, in the engine stalling abruptly (and I had to restart and wait another 30 secs after which it would not stall). This has never happened before even though I followed the same exact cold weather start-up routine in the past. Is There A Particular Part That May Have Degraded And Needs Attention?

Please note some other pertinent information:
Problem is intermittent
The compression is within specs. I had it checked by the Volvo dealer.
The engine ALWAYS delivers a reassuring positive healthy start even on those particular days when it stalled after placing in gear.
I drive very gently (rpm below 1500) until engine reaches normal temp in order to warm up engine components. I never allow prolonged free idling in cold weather at start-up since owner's manual advises against this action in frigid weather (max 30 seconds). The throttle body was cleaned by the dealer (which appeared clean already) but this did not help since the problem repeated after as well. I have oil consumption at rate of 1quart every 1200 miles (but there is never any smoke from the exhaust even at start up).
I have very good mgp numbers. Comparison of readings from the car's digital fuel consumption indicator against my other 3 cars (they are sport sedans as well) have repeatedly shown that the Volvo provides the best mpg even though this car is older and faster than them. The oxygen sensors have never been replaced.

Your input will be appreciated.
Thanks.
Ghassan.

From cold country. My sympathies! It aint that cold here but it will be. Things like isopropyl dry gas, injector cleaner (use half what they say twice) they love selling product. Like "Brille Creme" "A little dab will do you!" ---Oh boy does that make me feel old!

Let us know how you make out, good luck with the fix, - T
