a little hiccup in my Avalanche during idle so I figure I'll do coils and plugs (did a full tune up in Jan). I've looked online and everything says it fits our motors, this true? Then I tried finding the oem Delco part number with No luck. Just trying to order a set with plugs on eBay but don't want the wrong parts.
Also have that stupid 2nd gear studded
Thanks guys
