I often used aftermarket parts, but I guess in this case, should have went with oem

Sorry I never updated. We ended up trailering it to a ford garage. We installed the original injectors minus the one that seemed to be bad. We installed the one new injector, which the mechanic said was no good so he replaced with a new Ford injector? Charged up the hybrid battery and all is good. I checked the numbers again to make sure we purchased the correct (aftermarket) injectors, which the information said we did. We purchased from advanced auto parts. So for some reason, apparently the injectors we purchased were not any good.

The 3 old injectors along with 1 new injector are in car, all new spark plugs. Tried switching Coil #4 and coil # 2, tried clearing codes and I am still getting the #4 misfire code. When the engine is started, the ready to drive light is on but quicky goes away and says pull over immediately. Check engine light flashes and still the code I am getting is Misfire #4. Engine shuts off. Very strong gas smell, like it is dumping too much. I didn't include the strong gas smell in the other posts, but should have. It was very noticeable before as well.

All old injectors are back in. Along with the original spark plugs. I completed this last evening but then engine would not even try to start. I put battery charger on the 12 volt battery, even though I didn't think that was the issue. Today, new spark plugs are back in. Engine turned over and started, didn't sound bad! BUT..., still shut off after about 10-15 seconds! The only code showing is Cylinder 4 misfire? Would that shut engine down? Going to install 1 new injector in for #4 and see if that makes any difference? Another thing I noticed is the hybrid battery is very low or dead at this point. Will this prevent motor from running? Any suggestions / ideas?

No, I did not try any injector cleaner. Should think simple first! Well I will definitely try that. I made a appointment at a dealer but they can't get me in till next Monday. I would love to resolve the problem and avoid paying a high repair bill! I will keep you posted!

My daughter's car, she called and said it sounded like it was missing. I went out to check it out and hooked up code reader. I got codes P0201 Injector Circuit / Open, Cylinder 1 and also P0301 Cylinder 1 Misfire Detected. Car definitely sounded like it was missing. After it sat and ran for a while then it cleared up, the miss went away. We went to the local auto parts to buy injectors, but they did not have in stock at store, so we had to order. The car seemed to drive perfectly with no missing. She drove car a couple more days till she could get the car to my garage and switch vehicles. The miss seemed to come and go. We received the injectors and I also got new spark plugs since they seemed to be original Ford Spark Plugs. The care has around 122,000 miles on it. After installing all new injectors and new spark plugs, now the car will not run. Well, it will start up but seems to be missing and you can not step on the gas. It will only run about 15-20 seconds and shut off. I had read injectors were a common thing and thought for sure we were on the right track. After replacing all the injectors, I ohmed the old ones. I read good injectors should be between 11-18 ohms. I ohmed 12.4,13.6,12.3, and 19.8 . Although 19.8 isn't very far out of spec that at least kept me thinking that one could have had the issue. All new injector (that are in the car now) ohmed at 12.2 ohms. I was thinking (wishful thinking) maybe the injectors I received were not right? Now, I went back and re-installed the old spark plugs to see if it could have been an issue with them. I still have the same result, care will sound like it is idling for about 15-20 seconds then shut off. If anyone has seen this type of issue or would have any idea what might be causing it, any help would be GREAT!
