It's supposed to keep cranking until ignition is acheived that the starter convienience package,its normal operation.If the battery voltage is low then it will only crank when the key switch is completly folded over.So check battery condition under a load with a load tester if batt checks out then look towards the alternater.

This is a pretty common problem. I would change your valve cover gaskets. They run around ~ 50 bucks. If they are bad it will leak oil into spark plug well and cause a misfire. Very known on the 740.. Also if tune was not anytime not too long ago id change spark plugs while you at it. Then clear the computer and if you still get misfire on 8 try changing the ignition coil which is right about the cylinder with cylinder ignition coil 5. clear the computer. if you get random misfire and misfire cyclinder 5 after then its your ignition coil. parts store runs around 100 bucks

hello ryk786, i/m not a hundred percent certain, but I think the output speed sensor is located at the back of the transmission. With the pan removed, if you look at the valve body and see the EDS valves and connectors, look about 2 inches back toward the end of the case and you should see a connector by itself. There should be a retaining torx bolt and spring holding the sensor in place. After installing the new sensor, do not over-tightend the bolt. The torque should be around 5-6 Nm.

A tune-up and throttle body clean-up is a good idea, but mind you on those cars, the valve covers usually leak into the spark plugs and coils, causing the car to misfire. If you are replacing the plugs and find them soaked in oil; replace your valve cover gaskets or you will be back to the same problem soon after the oil soaks the new plugs back up again.

Depends how competent you are here and what sort of tools you have.You will also need to replace oil filter if you wish to replace oil within the engine.The oil has to be drained from underneath the engine and allow it to sit for few hours while draining as this will ensure all the deposits at the bottom comes off.
