I swapped my spark plugs today now car hesitates
I it seems its running on 4 cyl. Driver side header
is cool to the touch. Only thing I unpluged was the
driver side coils during the swap thats it. Now I got a
p0200
p0443
p0480
p0740
p0785
p1860
What the hell did I do wrong?
PLEASE HELP!

Check the connections again where the harness plugs into the coil subharness, its possible a pin or something got bent in the process. If everythings cool Im not real sure what else to look at. The P1860 bothers me though, thats a manufacturer trouble code and can sometimes mean serious things.

no codes if that matters.

Got it! 1 spark plug wire didn't click all the way.
Good God I almost craped my pants I thought I
had to shell out some big $$$$. Thanks Drew.
Now why did I get a trans code because of one
spark plug wire? Anyone?

I wouldn't worry about the trans code, as long as it doesn't come back - the computer was probably just confused when the engine was running so rough without that spark plug working.
