My 06 Pacifica has a misfire going on, I try everything, new plugs no good
check coils not the problem, any thoughts??

 

compression test

 

Do you have any fault codes?

 

My codes are P2305 & P0302.

 

Might want to google those codes.

 

Well your 302 is cylinder 2 misfire, and the 2305 is coil #2 secondary circuit-insufficient ionization. Cylinder 2 is on the front side relative to vehicle front and the right most relative to vehicle right. Check out the coil connections, pull and inspect the plug. You could swap a coil to see if the problem moves with the coil. I think most shops would try a new coil.

 

My first question is what engine are we talking about,....3.5 or 3.8?

When I was looking at these Pacificas to buy one about a month ago, I first saw the 3.8 engine and thought WOW, it looks like an old time engine I could actually work on myself. I mean at least change the plugs and do other little maintenance myself.

But I ended up buying a vehicle with a 3.5 engine. Couple of days ago I looked into the idea of just putting new spark plus in. WOW! what a mess trying to get to at least 3 of them!!. Looks like you need to remove t6he intake manifold to replace the spark plugs.
WHAT IDIOT designed that !!!
