My S60R 2004 runs rough and accelerates slowly, when I push the accelerator, hardly anything happens until I slowly release the throttle then there is a sudden burst of power.
I want to try another second-hand throttle body, when do you need to do a software update? Should I attempt changing the wipers in the throttle body? Vida revealed nothing, which makes me think it might not be the throttle body. Advice would be appreciated.
