Default 1999 S80 No Throttle Response

Hello

I am experiencing a very annoying problem with my 1999 6 cylinder non turbo S80, most of the time the throttle has no response whenever i press on the accelerator and other times it works just fine but with slow throttle response i put it on vida dice diagnostic cable and this is what i found:

i have had the following done with no use:

changed thee alternator
changed the throttle
changed the tps on the throttle with contactless one
changed the accelerator pedal

the car seems to work for couple of days whenever i disconnected the battery for five mins but then the problem comes back again and also I noticed that the accelerator has no effect (no throttle response) when pressed at the same time when pressing the brake pedal , not sure if thats normal

Definitely your the ETM (throttle body) ... Have it cleaned if you know someone, a lot cheaper than getting a new one installed. 99% positive this will fix the throttle response
