Code p0302 trouble
About 3 days ago my 06 g35 coupe was misfiring decently at idle but not throwing a code, decided to change out my spark plugs the same day. Today after i was out maybe 20min it started to misfire again at idle, then while i was giving it throttle on the drive home it bogged like crazy in 4th and the cel started blinking for the p0302 code. Injectors? Coil packs? If anyones got experience with an issue caused by this code
please let me know.
If you replaced the plug, and there was no oil in the spark plug well tube, then it's fairly safe to assume the problem is the coil pack. You can unplug a couple coil packs and use a digital multimeter to measure resistance across the pins and compare to cylinder 2 which is throwing the P0302 and more than likely there is a different ohms reading on the cylinder 2 coil pack.
You can also take the coil pack and swap it with another cylinder to see if the error switches to another cylinder.
P0300 is random misfire, if the last digit has 1-6 that corresponds to a specific cylinder.
