Question about Vehicle Parts & Accessories
The ignition is misfiring. I drove in heavy rain yesterday. do you think something got wet??
Hi. You may have a wet ignition coil. First you have to locate wet the coil. If you have a check engine light on and a cheap code reader you can check which one is misfiring. Code P0301 means cylinder number 1, P0302 cylinder 2, P0303 cylinder 3, P0304 cyl number 4, P0305 cyl # 5 and P0306 cyl # 6. Looking at the engine compartment at passenger side you will see cylinders 1, 3 and 5 from the front to the back. On driver side you will have cylinders 2, 4 and 6 from the front to the back. I recommend you to purchase a subscription at www.alldatadiy.com to get information about your cars so you can see how to perform a ignition coil removal/install so you can fix your car. If the coil is not wet you can swap the coil position with the coil from the next cylinder, clear the codes and drive the car until the check engine light comes back on. Read the code and if the code change to the cylinder that you put the "defect" coil, replace the defect coil for a new one. If the misfire does not change the cylinder, you may have a bad injector, bad cylinder head valve, bad intake manifold gasket and few other possibilities and for that I recommend you to take to an auto repair shop, because you will need special tools and a deeper diagnostic. I hope that helps. Take care.
