It wasn't engine knock. My passengers side rear cylinder wasn't firing. I had hand checked all my coil packs after I replaced my iacv, and the packs, and plugs all felt tight. However, while I was doing a compression test yesterday I noticed that coil pack wasn't on all the way. I pull the coil pack plug to find a tiny rock stuck in the plug. Removed it, reinstalled everything and she started right up no problems!

 

sweet man! thats great to hear!

 

Right on. I like when problems are simple.

 

^^ Me too! I still feel stupid though, how the hell did a rock get in there anyway?

 

My son must have put that rock in there.

 

The "Turbo Killer" strikes again!!!

 

good to hear it wasn't anything bad, but a rock how did that get in there?

 

I unplug the coil packs and usually set them on my porch whenever I change plugs, I did it recently and that's the only way I could possibly think of how it got in there. What must have happened is initially it was making contact because my car ran fine after the plugs, but I don't think I was able to actually "click" it on, and it might have wiggled loose.
