So I have an issue with cylinder 1 misfire. I have been replacing cylender 1 coil every week for 3 months now. I have taken it to 5 mechanics now all say that its cylinder 1 misfire....thanks. I need a mechanic that is good at finding what is causing the problem. The original problem occured 4 months ago when I replaced a valve spring. Help me please.

If you are sure about the spark plugs, run compression and cylinder leak down tests. If that doesn't show anything change the injector.

Can too much or too little fuel cause this problem?

[PCH]

Yes it can. Anything that makes one cylinder produce less power than others will trigger the misfire code. Bad spray pattern from injector will decrease power also even if delivers correct amount of gas.
