Car Forum / Mercedes-Benz Cars / March 2006300E Still Not Running Correctly
Hello everyone..... My 300E is still in my driveway and starts up without a problem on a cold start but cuts out sometimes after 2 minutes or after 5 minutes. When it dies, it sounds like it gonna stop then goes back to a normal idle and then again it couts out. If i hold the gas down, it will run for a little longer at around 2000 RPMS, then cut out. If i wait a few minutes, it starts up and does the same. Before it cuts out, the check engine light comes on. Here is everything I have replaced.... OVP Relay Fuel Pump Relay Fuel Accumulator Fuel Pressure Regulator Cap and Rotor COld Start Valve Spark Plugs Fuel Pump Check Valves Fuel Filter Ignition Coil Catalytic Converter O2 Sensor Crankshaft Sensor Most of the parts were replaced recently or in the past few months. Anyone here have any other ideas?- Chuck, Monmouth County NJ What diagnostic codes are displayed? Hi, C200 owner here :)) Did you do a PMS check? Maybe you're experiencing problems with ignition anticipation angle? I may make sense, since motor dies when it gets hot.... Check trouble codes - and visit www.demonoid.com. They have new 2006 MB WIS for free ;))) Andrzej > Hello everyone..... > [quoted text clipped - 20 lines] > Most of the parts were replaced recently or in the past few months. > Anyone here have any other ideas?- Chuck, Monmouth County NJ Did you change the fuel filter? > Hi, > C200 owner here :)) [quoted text clipped - 10 lines] >> My 300E is still in my driveway and starts up without a problem on a >> cold start but cuts out sometimes after 2 minutes or after 5 minutes. >> When it dies, it sounds like it gonna stop then goes back to a >> normal idle and then again it couts out.

Sounds like cutting off by building up the vacuum (or absence of) inside the engine. I once had a problem with a relatively new 280E driven in cold town only. The problem was double, a soooth closed hose from engine to intake manifold and a worn o-ring seal on the front crankshaft. The gas regulation system depends on correct pressure dates in the engine. At last after closing the cold start valve. Sawing revs points to a overloaded gas regulation system. SignatureRoland Franzius |
