Just an FYI, Delco Iridiums are made by NGK for Delco.

When I installed my Delco Iridiums, I confirmed this as they were stamped NGK.

 

I'm waiting for the parts from RockAuto!

I will keep you updated on the work until the problem is solved!

I will update as soon as possible!

Really many many thanks to you all!

Great Forum!

 

True. Actually, pretty much everything that is AC Delco branded, is made by the same companies that most aftermarket OE parts are made. Same companies, but how it's made and the specs to which they are made are different the last time I checked.

But as some examples, NGK makes some of AC Delcos' spark plugs (I believe only the iridium). Gates makes their belts and Raybestos makes their brakes.

So I will still stand by my statement that you can not go wrong with any thing AC Delco.

i've changed spark plug and spark plug wire but the problem persist.

The car runs perfect, I stop it and restart it after 40 minutes, it seems like don'go perfect.

I feel a little shake inside the car.

Do you have an idea?


Many thanks!

 

have it scanned for any stored codes. may give you some possible areas to look. even though the ses light is not on it can have stored codes. computer should see the missfire and react to it.
