P0300 p0305

Hi, my name is Devin. I am an auto repair expert with the Car Genius team here at RepairPal. I'm sorry to hear you're having trouble with your Wrangler. The P0300 and P0305 codes signal a random misfire and a specific misfire in cylinder 5, suggesting the issue may be deeper than spark plugs, coils, or fuel injectors. Since those components have been replaced, it's worth checking for any vacuum leaks around cylinder five and performing a compression test to rule out internal issues, like a burnt valve or head gasket leak. If you need more advice, have any other questions about your vehicle, or would like to get connected to a RepairPal Certified shop near you, we have you covered. Give us a call at 877-913-1554, and we will happily help you out!
