cheapest place for coil pack

[jfb]

Just changed plugs, the old ones were ngks! Just as forum said would proly be the case. They were fairly new. Have replaced with bosch ones. Have disconnected battery to allow ecu to reset itself. Will try it later. So will be looking for a coil pack maybe if this doesn't solve the problem!

Thinking ahead , if problem persists even after changing coil pack, how can I tell which ecu is fitted? It's hard to see! And is there a lot to changing one? Will there be electro technical wizardry and equipment needed? !!

Thanks

James
