My dad and i tested all the spark plug wires with a timing light and we found something very interesting. the rear lower plug wire only send about half the amount of shots that the other plug wires do. is this a bad coil??? please reply very soon because it is a semi urgent problem. thanks sooo much in advance.

The lower plugs are the leading plugs. You do not have a coil problem, I believe, because both plugs are fired by the same coil! It is the coil in front of the engine compartment with 2 plugs connected to it. If you are getting different spark patterns with 1 wire, chances are the wire is bad or the connection to the coil for this wire has a problem. Swap wires at the coil to verify. Hope this helps.
