firing order 1-8-4-3-6-5-7-2

It could have been 180 out when you bought the car, but it will still run fine.

I'm sorry sireland,, but a motor simply won't run 180* out,,.

Think about it,, you'd be sending spark to a cylinder thats in overlap,, both valves likely slightly open,, exhaust gases have just been pushed out,, there's little or no fuel,, no compression,, just an open intake valve to "pop" thru..

hope it helps
