check for fuel and spark
12-24-2012
my car starts right up but it sounds and runs like crap
12-24-2012
check plugs conditions.
12-24-2012
no way you jumped timing. when was your last tune up?
12-24-2012
new plugs a month ago cleand my air filter then too I do regular maintenance all the time
12-24-2012
test the coils
12-24-2012
why would it say random misfire
12-24-2012
this all started after I got stuck in the snow was slowley getting out then I hit a dry patch and my car shot out like a rockit.Now I have this prob

random mis fire means they are in every cylinder all over the place.
so im guessing here, you used platinum plugs right? if so change them, thats your problem. you want to use iridium plugs. nothing fancy, no Bosch 4 or any of that stuff.

I have auto lites in it 605

copper core plugs?
12-24-2012
Yes they are copper core

Check your ground on your icm
12-24-2012
Ok but what is my icm I'm new to all this stuff
12-24-2012
ignition control module. It's under the coils
12-24-2012
the icm is under the 3 coil packs. there is a black wire with a loop on the end, it gets bolted to the side of the head to the coil brackt. make sure that wire is in place and tight and not broke off.
12-24-2012
yes that wire is tight and i traced it right back to the loom
12-24-2012
next step would be to have the icm tested.
you need to take it off and bring it to autozone or another parts store to be tested, they do it for free.
12-25-2012
Ok I will give that a try and see what happens
