Mazda Protege5 Spark Plug Question.

anyone tried those "G-POWER" , BKR5EGP - 7090's ??

I may throw a set into my (new to me, 120K miles) MP5 and see what's what....

So I reset the CPU and put the new (bosche) plugs back in with the exsiting coil pack and wires. Everthing is back to normal except for a small rough idol...

(1 week later)
...well the rough idol got worse and now the engine light is on again.

I took it to a shop, they ran the code and one of the fuel injectors is leaking. Stupid me, when i was first starting to take the plugs out i accidently started to take the injectors out. Well I guess I did not put it back scure / properly. Any way the shop is saying it will cost $378 to replace the seals and clean them. Seems out ragious since it is right on top of the engine. If I knew what to do I would do it (look were that got me the frist time).

Any suggestions? The shop also said to have a look at the timing belt, but I think I will put that off until it gets closer to the manufactures recommeded milage.
