2004 chrysler sebring 2.7 liter engine p0301
Hi, did you ever fix this problem? If so, what was it? I'm having the same exact problem with the same exact car and engine.
Thanks

Code P0301 = Cylinder 1 Misfire Detected
Start with the “easy to check” items first...Some of these checks/repairs require specialized tools or equipment. A trusted repair shop or dealer would be would be advised to correct this problem.
Try changing the spark plugs, Check the coil, TPS sensor & MAP sensor voltage. Check the fuel pressure, check for vacuum leaks including intake manifold. Dirty or plugged injector, timing, compression test-including leak test--meaning, put #1 on TDC then charge the cylinder with air (~30lbs), and check for leak via exhaust/intake. Update PCM to the latest software, Worn camshaft.
