Briefly what I have accomplished to do with what I have saved (not daily drive). Inner and outer tie rods,alignment front and rear (still saving for strut), rebalanced tires(really improve handling and cleared wheel shaking),Coolant flush and refill,Oil change synthetic blend,Air filter,cleaned engine harnesses and wires with electrical cleaner.

Alright now I am moving to packs and plugs I know you have to go with platinum's but would I be ok with just replacing plugs for now? am sure they probably need them. As far as coil packs can I hold off for now and am not getting a code, just not sure when they where last done .

I'd just go with whatever the OEM specified NGK platinum plug is. I believe it's the NGK PFR5G-11. Your best deal is probably buying them at Advance Auto with one of their online coupon codes. I'm finding them searching the part number 2647 on their site. Run a google search for "advance auto coupon code" and you'll find one that should get you $30 off...

If you're not having misfire problems or codes, I think it's fine to hold off on the coils for now.

Alright I will do that and my brother works at the advance so I can get a extra discount, can anyone give me the easiest route for this procedure maybe? Or any problems to watch for while remove and installing plugs

FSM = MA-12 + MA-13, you want different sized extensions to have a clearance to turn the ratchet with a "joint socket extension" so the socket can maneuver onto the plugs, oh and plz use a 3/8? socket specially designed to extract the plugs, it makes life so much easier, and make sure you use boot protector grease and a anti seize grease for the plugs.
