It should try to start at least. It may or may not actually start but you should hear it fire on the 2 good plugs. Why not just replace all 4 spark plugs?
your engine will start but run badly on a multi cyl. ie. more than one only 1 plug may be down, not often more than 1 together
it could be as minor as a tune up (spark plugs and wires)(or bad distributor coil pack). or possibly a faulty fuel injector.
Possible reasons why you have no spark: Bad ignition module Bad pickup coil Bad engine control module Wiring issues
No, that will have no effect on the battery.
The most common reason for a vehicle to run rough when it is cold is bad spark plugs or bad spark plug wires. Change the spark plugs and spark plug wires.
bad spark plugs
Bad spark plugs? Bad plug wires? Bad valve? Bad piston? Bad coil? (new Fords haeone for each cylinder) Bad spark plugs? Bad plug wires? Bad valve? Bad piston? Bad coil? (new Fords haeone for each cylinder)
Misfires are commonly a result of bad spark plugs or the wires connecting to your spark plugs, There is a spark plug for each cylinder of your vehicle which affects your cars ability to start and shift up in gears, depending on which plugs aren't working.
on the tip of the plug it means you have bad piston rings in that cylinder.
It COULD, but multiple plugs would have to be very fouled. If just one has gone bad, the vehicle would still start, but would just be "missing" on that one cylinder.
Bad coil? Bad coil wire?
That error code is for a single cylinder misfire. Bad spark plugs or wires can cause this as well as a bad fuel injector.
2008 malibu 3.6 L code says PO302 misfiring Misfiring in number 2 cylinder. Could be an ignition problem with a bad spark plug or spark plug wire. Could also be a bad fuel injector. Could also be a mechanical problem such as a bad valve. Start with new plugs and wires.
Yes, bad spark pugs or plug wires can cause the engine cylinder to misfire which will cause the engine to vibrate.
No spark from coil, bad plug wires, or bad plugs.
your engine will start but run badly on a multi cyl. ie. more than one only 1 plug may be down, not often more than 1 together
you need to remove the intake manafold, and throtle body. not to bad
