S60 b5244s poor acceleration when cold
Hi Guys,
New Volvo owner here! Bought myself a 2001 S60 2.4 170 with the b5244s engine. I had the ecu replaced bc of lack of power and hesitation. It threw the fault code ecm-3400, (knock sensor signal too low) which other threads stated was due to a faulty ecu. Well, after the ecu change, the car runs sooooo much better when warm. But when starting from cold in the morning it still hesitates, stumbles and got poor acceleration in the first couple of miles. After that it runs beautifully. It's got no stored codes, the temperature gauge is dead center after app 10 min, and the etm is quite new (3 years 40-50000 km.) What do you think? Br Niels |
