    Po302 2006 Subaru sti. Did all swaps. Compression and leakdown test all good. Noid test on injector connector good. Used smoke machine for vacuum leak, no leak found also did exhaust side. Changed upstream and downstream o2 sensors OEM denso. What did I not check???

    My car had an epc and check engine light at the same time. Then this code came up. My car dont have a disruptor cap so its the spark plugs, coil, or fuel injector?

    I have a 2011 Prius and got the P0302 Code. Replaced the coil, but still have the same issues. Mechanic is saying there is an issue with the Water Pump. Does this relate to what is happening possibly or should I look at the spark plugs next?

    Please help. Have 2004 Chevy Colorado and shaking mid-firing engine literally started over night. Check engine codes are p0171, p0014 and p0302. Where should we start first

      Anything I say is a guess, but has the oil been changed regularly? If the VVT solenoid, which oil flows through, gets clogged up, it can cause issues such as a P0014. Also, I would test the components on cylinder #2, such as the coil and injector.

      Full synthetic oil changed regularly. Replacing spark plug and injector code today. Will update

      If the injector has a spray problem, it might work, but there are several things that can cause the issue. It's best to do some tests first.

    I don't know what to do. I only have the code p0302. I completely replaced every spark plug and my entire coil pack and every fuel injector as well as thoroughly clean everywhere. It drove wonderfully for a week after I did the coil pack and now it's back to the same awful driving and code

      It needs to be diagnosed, but if all the components are good, I would check the wiring.

      It needs to be diagnosed, but I would test the wiring and the injectors on cylinder #2.

    2018 toyota camry SE 2.5L
    I did everything. Fuel pump fuel filter New. Fuel injectors and spark plugs. New.
    Did the swapping. Still same code. Cleaned out Fuel rail.
    When accelarate fast my misfires hits and than a loss of engine power comes up.. loose A LOT of power.
    When I pull over disconnecting coil and or Fuel injector doesn't change the engine meaning the problem is sitting on Cylinde 2 for sure. But only does it after that acceleration and continues to fail Unless I turn off engine for awhile it goes back to normal. Slight misfire but that cycle continues. Wires??? O2 sensor? I clean out the MAF sensor don't seem to have any intake valve leaks from my tests...
    Help needed anyone. Thank you guys/girls so much God bless !

      Intermittent problems can be hard to troubleshoot. It sounds like a coil going bad, but that is just a guess. I would remove the spark plug and, see how it is burning, match it to a burn chart to see if it is a fuel or spark issue.

      @HVAC_Mechanic the whole time. It just needed OEM spark plugs. I got auto lites from autozone and that's why I still had the issue. Learned a huge lesson for this vehicle and for the future vehicles.
