Default Need Help with S60

2001 Volvo s60 2.4 turbo. 134k miles. i have recently changed the spark plugs and fuel filter. i removed the ETM and cleaned it out but still having the same problems. When i am driving at a constant speed i feel like the car is "bucking" or slight hestation. the car does not do it when it is idling or gaining speeds, only when im at a speed for a short period of time it likes to do it. i do not have any codes showing. any ideas on what can be causing to the car to feel like it hesitating at a constant speed?

My 2004 volvo s60 67000 miles. need help by volvo techs or volvo gurus?
with just about 67000 miles on it has had some wierd things going on
i have a weird thing happen and its only in hot weather, i live in a 4 seasons state and 3 out of the 4 the car runs great. but in summer i get some weird driving issues. the car will sometimes lerch forward unexpectedly or the brakes are grabbing the calipers , and says a severe break failure has happened, sometimes it might loose power and other times it wont, the radio will still work, but nothing else will locks, mirrors, windows, gauges all drop, time and temp go blank, as well as the trip. ill pull over to the side of the road turn the car off and than turn the car back on i will have a srs airbag service urgent on my dash sometimes it will happen again right away and other times it wont happen for another couple of days. i also had the car taken in last summer and the dealer said there was a fault happening somewhere near the engine and put a b block and checked the electrical connections. but a year later im having the same problem. i have been reading around and it sounds like it is a ecu problem (is that the same as the ecm). i also will refer to this question because i get the same error codes but i wanted to give a more accurate description. i could use an answer pretty quickly.

Can you remove the ECM for 5 minutes then reinstall, start/drive vehicle for 15 minutes to reload brain.

Do you notice at what speed it does this? Should usally happen round the same mph and if it does it's just your coil packs ...when you change your spark plugs you should always do the coil packs too I learned this on my own after it happened twice to me my car would hesitate or buck around 40 mph and only at that speed it was my#3 spark plug ..it could be any of them though
