I ordered 3 ignition coils because they didn't have more original parts. I will get the rest as soon as they get some more.

I will also look into the link you gave me although, my problem is not related to cold start. I have seen that before but couldn't find anyone else having the same issue as me.


I will post my results as I check things.


Thanks again!

You most likely can see if those coils fix your problem RIGHT NOW! you have to make sure you replace the coil where you got the misfire code(s) that you said you didn't have before but now say you've had. They are the easiest thing to replace. Look how the top of the coil cap on the new one swivels. go to your engine pop that cap upwards unplug the coil wire from the coil and and then pull that coil out. Sometimes it takes alot to pull those straight up and out. Getting leverage on those with your fingers is hard sometimes but it will come out. drop the new one where you took the old one out (push down) remember which ones you're replacing. Plug the coil wire back in and snap the cap back down and see if she purs like a kitty. If that fails then I would be rethinking what spark plugs are actually in there. If that fails then I would be checking compression too. but hopefully you don't have any hidden reasons of why you should of checked compression first.

one thing I noticed on this engine is they don't have like a 10mm bolt or something to hold the coils down like most cars and trucks I've seen. Just sayin.

remember you need to make sure you're replacing the coil or coils where you experienced your misfire codes or this will have you chasing your tail.
