My car C240,2005 Model won’t change gears.
My is not accerating.The maximum speed is
going is 80km/hr it can’t go above that,and
the gears are not changing as they were.What
could be the problem?
When the catalytic converter is clogged, this causes exhaust gases to back up into the exhaust system not allowing the engine to breathe properly. This should also cause a check engine light to come on as the O2 sensors should be reading the incorrect amounts of oxygen in the exhaust gases.
Ok thank you.Then what should l do?
Have a mechanic diagnose this to find all the problems involved; it's likely that something is causing a misfire that's lead to this. I suspect that you might have to replace the catalytic converters, as well. But only a professional diagnosis will tell you.
