I have the following problems regarding my 190E and I appreciate if you could share some opinion/advise.
1. The engine have no problem in starting and high RPM, but when idling, it is a bit rough at around 800 RPM, it seem like miss fire once a while. I have replaced the spark plug and vacuum hose under the air filter. but no luck. Initialy, I though it was due to air cond engage but this happen even the air cond is off. Any advise what else to look for ? 2. How do I check/ensure the engine mounting is bad? I was told there are 2 types of mounting (round and square). Is 190E using the round type ? 3. The engine oil level drop 1/4 after about 3000KM travel, and I hardly notice any white smoke from the exhaust. Confirm no leakage. Actually, the car was left for about a year without start. Could it be the ring is jam ? Should I add some oil treatment to improve it ? Thanks in advance. |
