Can fixing a cylinder 1 misfire on a 99 Cavalier 2.4L be ad simple as replacing plugs and rubber boots on the plugs?

Start by replacing all the plugs and plug wires. If you still have a miss, it can be a bad injector or low compression on that cylinder, which may mean a burnt valve or bad rings. as an add-on to the previous post, there are a few cheaper methods of checking your ignition electrical system. first would be to start the car at night and look under the hood at the wires, plug boots and if you can see it, the ignition coil. DO NOT TOUCH THE WIRES! if there is any kind of problem with these components, such as insulation failure, cuts, breaks or abrasions in plug wires, you may see some arcing and sparking. if you see this, the spark is going somewhere other than the plug and not causing ignition. IF YOU TOUCH THIS, THE VOLTAGE (UP TO 30,000 VOLTS IN A PROPERLY OPERATING SYSTEM) CAN END UP HITTING YOU! another cheap way to test for spark is a spark tester. you can usually pick them up from your local auto parts store (i know checkers/kragen/advance auto parts carries them). to use this, pull each wire from its plug one by one, connect it to the tester just like you would a plug, ground the tester to a bolt or other bare metal, and turn over the starter, if it's operating properly, you should see sparking from the tester electrode to the grounded housing. if they all work, your problem is elsewhere. Don't rule-out your coil.One of mine went out,it only showed #2 cylinder misfire.On another z24, #2 misfire was caused by a cloging fuel injector.
