Moin, my car a Volvo 850 2.5l 144hp 10V which unfortunately runs much too fat or does not run long after I clean the spark plugs and start it again after a shorter time or if you want to give gas it takes a relatively long time until the speed rises and sometimes when you give gas it goes out. What I have already checked if it works: 1. Ignition distributor finger and distributor cap is still perfect and not old. Ignition cables are not old (all so 1.5 2. Ignition coil measured and also runs. 3. Ignition spark is also very strong with all 5 spark plugs. 4. camshaft sensor works. 5. crankshaft sensor also works. 6. throttle flap and everything associated with it. 7. he has very good compression too. What I would have suspected in is the sensor for the throttle flap and the temperature sensor from the cooling water. Or what would you say someone had already had such a problem or can me someone else help I hope someone can help me.
