08 Aveo5 Shake or Miss

The ones that were in my car originally were NGK copper made in korea, unlike the usual acdelco, so I just went from regular copper ngks to iridium ones. Supposed to burn hotter too, but like said above, nothing major you will notice.

2 things:

somebody said to clean the map sensor, but aveos are not map, they are maf.

and, sergea, how dare you tell these fine members that changing your spark plugs does not give extra hp. When I changed mine to iridium, I gained 10 million + horsepower. I was going thru tires like mad

is you out of warranty viper?

Ok, this is the time to ask really stupid questions,

I popped the hood to look for the plugs. There are 4 wires coming out of the top of the engine. I figured, the thing where they hooked up to must be the plug assembly. I pulled one of the wires off, and it definitely is not the location of the plugs, from what I can see.

So, do I need to unscrew the top of the engine, take that black top off, and the plugs will be there?

Please, Please advise...


BTW: I got NDK Irridiums

ok, the 4 wires that go acrossed the top of the motor (thicker, like 4guage amp wire) are what you want, but follow them to the valve cover (the big black square with the 4 wires coming out of it). Pull them out but only do 1 at at a time. After you pull the first wire ot you should be able to look down the hole and see a silver nub in the middle. Grab a 17 mm (?) deep socket and gently put It down over the plug and gently turn it until you feel it catch and fully resist you. Then carefully turn it to loosen it but be careful as you don't want the plug to break but know it will put up a good resistance. Turn it until the plug is free, gently put new plug into the well of the valve cover, then turn it to tighten it. Tighten it until it's nice and snug, take the long rubber grommet end of the plug and push it onto the plug until you feel it click and then repeat this 3 more times. The reason I want you to do one hole at a time is there is a specific order the wires go and I don't want you to mix them up, even tho they are all cut to length.

Or just go to your local store and ask them for a spark plug socket, and make sure you bring one of your new plugs to get the right size, there's two variations. They'll have rubber insert in them that will go right over that shiny piece that mike is talking about.

Tighten it until it's nice and snug, take the long rubber grommet end of the plug and push it onto the plug until you feel it click and then repeat this 3 more times.

Just to clarify, he doesn't mean push it on to repeat the click three more times. One click per hole is enough.

I was trying to spare them the price of tickets, car crashes, and, of course, tires.

Well, I replaced all 4 plugs with hdk iridiums.

I am happy to say the problem is fixed. No shaking, engine light off.

I got the code that told me the problem was cylinder 1 misfiring. So, changing the plugs fixed it.

Thanks for all your help given me to solve this for me, and all this whole situation cost me was $24.00.

Ciao,
