Hello guys.
Can a bad clutch cause misfire.
I have a 1997 base boxster with 5 speed manual transmission. I bought the car recently and mechanically was not in good shape. Clutch went to the floor soft once and I drove all the way home in 3rd gear. I then flushed clutch and brakes, put new spark plugs, coils, and change air filter. Car came to life and was driving good for 7K KM but recently clutch went out again and soft. The gear did not engage or disengage even pulling and pushing hard on gear. I then disconnected the battery thinking it might help rest computer and other electronics hoping clutch comes back to life. After reconnecting battery, I put the car in 3rd gear and started the engine while pushing on gas pedal and car started misfiring. The engine was perfect before the clutch went out and before I disconnected the battery. I have checked the oxygen sensors and all plugs and coils and all look good. I get misfire on 4, 5, 6 and the car dies after 15 to 30 seconds. I am thinking the cause of misfire is clutch. The car is in neutral and even without pressing on clutch, it starts and runs for few second and then dies. It could be the flywheel is stuck preventing the engine from spinning properly. The car appears to have the original clutch. The car currently has 120K KM or 75K miles. Please advise. Thanks
