Something happened, I was shifting from Parked to Driving and when I put my foot on the gas there was a loud noise that sounded like a popping noise. My Service Engine Soon light is on and when I start it up there is a ticking type of noise. What do I do?

 

did it start to misfire? pull all the cop's and see if a plug blew.

 

if a plug blew you will see it flopping around, mine was anyways, just banging against the fuel rail

 

i've never seen one that blew out. i just figured he had already looked and didnt see anything.

 

I just checked my plugs, I don't have the right tools on me. I went check the 4 plugs on the passenger side and the 3rd one from the front of the hood was loose. Does that mean that it's blown?

 

most likely, thats the same one that went on my. Start the truck and go take a look under the hood. If it sounds like a steam engine and you see the COP flopping around its blown

 

if it can still be tightened down then no. if you can pull it out then yes. if you find one that is blown out then you need to fix the threads in the head or get them fixed and do a full tune up. since that one is loose i suspect there are a couple loose and one blew out. if it was a spark plug.
