Hello, I have found something new again, when the 133PK NG engine is warm. If it is warm (130 degrees), as well as in the picture, I drive just about 160 km/h at 9 degrees/dry outside temperature. It then unfolds its power very funny when accelerating, until 4000 hesitantly normal, then suddenly it pulls once, as if it had a thrust and then again slow to little acceleration. That probably the circuit switch is defective, I have already tested, see picture. I turn it off/on it runs normal again for a while, then after about 10min. it stays stuck again at 1150-1200. In the last days I changed this: – battery 72ah – 10W40 oil + all filters – spark plugs – fuel pump + filter – thermostat + sensor – 2x oil pressure sensors (which has lit) What else? – circuit switch! – petrol pressure regulator possibly – KAT + Lambda KM STAND: 215,000 Someone else valuable to say?
