Well i just changed my plugs/wires and for whatever reason it doesn't run right it misfires bad and the check engine light keeps flashing ...

I belive the firing order is 1.6.5.4.3.2 Is that correct?

If so what else could be the problem,, i went through the wires and all seem to be on the correct plugs... all the plugs look find also when i installed them..

could be many things,

wrong plugs
wrong gap on plugs
ICM (under the coils)
Coils
wires not connected all the way onto the plugs

Plugs/wires are correct

and the whole gapping thing.. .how do i do this exactly?

ICM (under the coils)
Coils

How do i check both of these? The car was fine befor i changed the plugs/wires so im clueless as to what it may be..
