Hello, Got a misfire code in my 3.7 V6. 1st it was a #1 cyl. misfire. I took off the coil but the bolt didn't come all the way out so instead of forcing it out, I bolted it back down to check if it should come all the way out. The engine light went off. a few days later, it came back on and with a "multiple misfire" code. Has 70K on it. Just bought plugs and am gonna try that 1st. Any other ideas are welcome and appreciated!

Funny, I have a 08 3.7L and I'm getting a cylinder 4 misfire (P0304) - just started a couple days ago. From what I was able to read up on spark, fuel injector and coil are the top three places to start. If you do some google searching on a misfire code, you might get some other ideas as well

Could start by switching your injector to another and see if the code changes from #1

Thanks for the input. It started with #1. Light went out. a week later it came back on as a multiple misfire. I can tell when it is misfiring and the light hasn't come back on again. I did run some Seafoam thru to see if that might help out injectors.
