check engine lite blinking, car shuddering. Need diagram and instructions on how

We have a 2001 GLS 2.o. The coil pack is not on top of the engine like on the other ones (2003 etc). Can you send a diagram or something that would help us out more? we are definitely not mechanics, but not afraid to try. we don't have a lift either. Tested it with code reader from Advantage auto, definitely 2nd cylinder PO302 misfire. The coil pack looks to us to be under some kind of filter or something. Also, it doesn't look like individual coils, but rather, looks like a pack (or a box). Really appreciate anything. We are strapped for cash.

why would you change the whole coil if you only have a misfire one one cylinder?yes it is one assembly.all 4 wires hook to the coil pack.i know about the tight on cash!why not start with the simple things first?why not change the plugs,or at least the one that is misfiring,or the wires?i think you have to use a special tool to remove the wires.that tool is $40.00,and that's on e-bay.your coil on e-bay is 1/3 of the price you gonna pay at the parts house.your car is 14 years old.i order all my parts from e-bay,because of the HUGE MARK-UP AT PARTS HOUSES.it's all aftermarket anyway.i have never had one single problem with any of the parts i have got from e-bay!but that's up to you.read below!! If the engine has a Secondary Air Injection Pump, the pump will be mounted above the ignition coil, and will need to be removed for easier access to the ignition coil. The SAI Pump bracket is mounted to the engine via 3 6mm allen bolts. Remove those 3 bolts and move the pump to the side (disconnect the wiring if need be). The ignition coil is held in place via 3 10mm hex screws or 5mm allen bolts. Un-clip the harness plug from the side of the coil (push tab in and pull up on connector). Transfer one ignition wire at a time so that you do not mix-up the firing order.good luck.
