@JohnMat. Thanks. Good to know I’m not alone with with this annoying problem. BTW if you disconnect the speed sensor at the right wheel is the high idling also permanent gone ?
@RogG. I’ve tried in the good car both TSM working normal. Equal which TSM is in. If I put In the bad car the TSM from the good car it blows the fuses 7 -9 -10 when I turn on the main lights. If I put the TSM from the bad car in the bad car the fuses don’t blow when turning on the main lights. If I switch on the alarm lights in the bad car without switching on the ignition (key) the fuel pump start running equal which TSM is in.
@Richard. I’ve swapped all engine components one by one as far as possible. Including the whole throttle housing with all components from the good car to the bad car. No results. With contact switch I mean turning the key at the steering wheel in on position. With alarm lights I mean when both turn signals starts blinking together. Perhaps hazard warning light is more correct. About the fuses see above to RogG
@All. Just back from a new test ride. 15 km. normal idling when coasting. Next 5 km. intermittently high idling. Disconnect speed sensor at front wheel from that moment on normal idling all the time without speed indication. Connect speed sensor again, next 10km. normal idling. Suddenly out of the blue high idling again. You can feel this high idling is back as the reaction from the engine specially when going downhill. Now all lights working normal again. 😳 Switch hazard lights still turns on the fuel pump. 😱
