Spark plugs, seal, exhaust, cat converter, map sensor????
Where tooooo start!!! Bought used 2000 madza
millennia supercharge. After 1 month has knock
,vibration, codes,oil, and honey combed shaped
buildup from converter in exhaust, overheating
inside car melting foam and burning..... Codes are
for map sensor and spark plug. Oil is found in
cylinder 6 spark plug.... Bad idle and acceleration.
Horrible in gas! I have no idea where to start
Start with a compression test to determine if you get a low pressure reading on cylinder #6. Cats getting hot is an indication of unburnt fuel entering the exhaust. The cats will clog quickly if not taken care of.
