What would cause multiple misfires?
Wet/damp/faulty ignition wires, contaminated fuel (water), worn out spark plugs.
What would cause your 1996 grand prix gtp with the 3.4 dohc to have single and multiple cylinder misfires?
POSSIBILITIES: Faulty spark plug - faulty ignition wire - distributor rotor needs replacing - distributor needs replacing. The most common cause of multiple misfires on the B20 / P75 engine used in the 1999 CRV is valve recession. this is a well documented problem on these engines. Repair usually requires replacement of the head.
What could be wrong with a 1999 Dodge Neon that misfires when put in gear and has a very bad fuel smell inside the car and registers fault codes 27 43?
If you're only getting a lean indicator and no other problems you might have a vacuum leak or possibly a problem with the EGR valve. The multiple misfires (assuming P0300 or specific cylinders, P0301 ~ P0306) sound like lack of fuel to the injectors causing misfires, also resulting in O2 sensors "sensing" lean mixtures as a result.
Try changing the fuel filter. It'll be fuel or spark related, so start with the cheapest thing. The problem was the distributor cap, I put a standard motor cap and a AC-Delco cap on it. Water would get up and cause the misfires. Summit has Accel products at a good price (less than AC-Delco and Standard). Its been 6+ months and no misfires.
What would cause multiple cylinder misfire. I put new plugs and wires in. The light went off. I drove about 25 miles then it came back on. I drove about 100 miles now waters in the oil any sugestion?

Misfires can be caused by many things. The most common causes are ignition system faults, fuel metering problems, and mechanical engine problems. A misfire caused by an ignition system fault or an overly rich fuel condition can lead to severe engine damage (requiring rebuild or replacement of the engine) as well as (less costly) damage to oxygen sensors, catalytic converters, exhaust system components, and carpeting. Misfires, regardless of cause, can damage automatic transmissions and powertrain…
The vehicle would run very badly if at all. There would be large amounts of black smoke coming from the tail pipe. Because diesel will not burn as well as gasoline, the engine would have multiple misfires, which will cause stalling issues. With newer cars, the amount of unburnt fuel being dumped into the exhaust would cause the failure of oxygen sensors and the catalytic converter. In severe cases, the engine could hydro-lock (when an…
Is it easy to misfire a 30-40 Krag Carbine If so how do I properly use the action to prevent misfires?
The cause is almost always an ignition system issue, cyl #2 is most likely getting no spark! When these ignition components go bad, they can cause misfires: Spark plugs, spark plug wires, and distributor; cap, rotor, coil(s), ignitor etc. It is also possible that the fuel injector for cyl #2 is not spraying!
A flashing check engine light means you are doing serious damage to your catalytic converter due to repeated misfires in one or more cylinders. If you get a code scanner (or go to an autozone, oreilly's etc. where they scan it for free) you will see a code such as P0301 (misfire, cylinder 1). Your catalytic converter is probably shot now. If it is and If you live in a state that does emissions inspections…
