What would cause a 1993 grand am 4 cylinder to miss and the exhaust to become red hot?
The exhaust pipe will turn red when the engine is running lean. You may have an EGR valve problem, vacuum leak or other problems that can cause the engine to run lean. A lean running engine can burn valves or pistons and causes other problems. Whatever the cause, it needs to be repaired before you put more miles on the engine, otherwise you'll ruin it, if you haven't already.
What would cause your 1996 grand prix gtp with the 3.4 dohc to have single and multiple cylinder misfires?
There are two O2 sensors on a 2005 Grand Caravan and are located as follows: On 2.4 L four-cylinder engines, the upstream oxygen sensor is located on top of the exhaust manifold, above the flange. On 3.3L/3.8L V6 engines, the upstream sensor is located on top of the rear exhaust manifold, above the flange. The downstream oxygen sensor is located on the side of the catalytic converter on all models.
The most likely, and expensive, explanation is a cracked cylinder head or leaking head gasket. If the exhaust blows white smoke when hot and smells sweet like sugar, you have a major engine repair. The liquid that flows out when you start the car is coolant that has condensed back into liquid after the exhaust system cools.
