The first thing you might suspect is a misfire. Check to see if all your spark plugs are firmly attached to their spark plug wires. If that is not the problem, pull the plugs and inspect them (making sure they all get back to their original spot or firing order). Next, check all the spark plug wires. Hopefully you will find the problem and it will not be water in your gas.

spark plug wires may be bad. when have you changed spark plugs? look under hood when it's dark to see if there are 'sparks' coming off wires.

Low compression on cylinder 1 bad skip if you idle it up the skip will go away and also it runs fine while driving


If there is low compression in one cylinder the fault wil be shown more at IDLING as the engine will not be smooth. So there will be reduced power and it might also skip.
In th long run you will have reduced power of the engine even as the engine will not show on higher RPM and thus the fuel useage will be more.
It will be good to check out and estimate to get the compression corrected to all cylinders.

How did you determine bad coil? was it not sparking period? I ask because coils rarely if ever go bad... What is the fuel pressure? Are the injectors firing? Spark plugs fouled?
Other sensors to check: Coolant temp sensor? Manifold air temp or intake air temp sensor? O2...These will change your air/fuel mix at temp if they're bad...
