Having problems with your 1999 Oldsmobile Intrigue ?

Overheating, Miss Firing, and Running Rough

\015 My 1999 Olds Intrigue is running hot and we've replaed the Thermostat, Water Pump, and even flushed out the system.. It's miss firing in random cylinders and running rough only when it's hot.. When it's cool, it runs like a dream... Think maybe headgasket? but no anti-freeze is leaking.. Changed also Mass Air Flow Censor, and replaced spark pluggs and wires..\015 Posted / edited by AnonymousUser on : 10-12-2018

Answers :

Smell the coolant. Is there any hint of gas smell? Also look at oil, any coffee coloring indicates problems.
