3.4 engine ticking noise

Never has the check engine light came on, or flashed. Yes comes on with other lights when key is in ignition

 

I did redline the engine a couple times cleaning out carbon deposits...

 

just keep driving it

 

Check the plugs. They can get loose, particularly on the 3.4.

 

Now I’m scared

 

RED is the international color of
DANGER
WARNING
DON'T DO IT

 

When I feel the injector coils on the passenger side of motor , the middle one seems to feel like it’s vibrating more then the rest

 

Exhaust seems to make a cough like noise.. like it’s missing

 

newer oil change and put about a ounce of seafoam into engine before this was ever a issue.... this was about a week ago going after a different problem I was having. Should I change the oil ?

 

SOLVED: engine tuck came from a spark plug that has play in it. Felt the injectors and middle one felt like it had a lot of ticking to it. Boot is torn on injector coil, but spark plug had weird up and down play. Posting video in a sec. highly recommend checking plugs for play.

this was my issue. Stoked !!!!

 

Cool you found the fix!

 

That’s great. My 02 has been doing that too, and only when it’s warm as well, not quite as bad but worth checking the plugs. Thanks for sharing.

 

Congratulations! If you need a new injector pigtail, I bought mine at O'Reilly. If you are careful, you can pull the wires out of the old and transfer them to the new plug socket.

 

///Meant coils not injectors ////

 

I noticed that my engine would kinda spudder without sending a code which led me to believe it was spark related

 

I think the noise on mine is more of a chirping and appears like it might be coming from an after market water pump. Probably ok, just isn’t that smooth hum I’d prefer. Plugs look fine but do need replacing.

 

Might wanna check to make sure you don’t have a bad ignition wire or Spark plug if your getting misses. They can tick if they are bad, could also be injector going bad.

 

Although ticking is gone with new plug, I still have a miss that just happened today. Finally as I was going up a hill in 4th gear Truck started shaking and shuttering until cel flashed. Def a misfire, the plug cylinder coil is torn and had rubber all inside the hole the plug goes into... think it’s running hotter ?
