Hey it might just be me not tightening them enough. does anyone what is the rewuired torque in the plugs for the 5vz-fe. I'm using the good ones from the dealer (denso) They truck is misfiring, this will be the 3rd time i tightening them. whutcha think?

 

My FSM sez 13 ft/lbs. Seems a bit loose to me but they are the experts.

 

Its possible that you crossthreaded them and now they are leaking. Happened to me on my 3vze.

 

No, I dont think they are crossthreaded they screw in awful smooth

 

Thx!!!!!!!!!!!!!!!!!!!!!!!!!

 

Wow thats crazy. How much were you torquing them down before?

I usually just go by hand, and tighten to they are snug with a 3/8" ratchet, then do 1/4 turn after that.

 

x2 thats what i do with everything

 

My plugs are staying seated now, finally. I had to change a coil pack that was jumping spark for a while now then threw in some new OEM wires and she purrs like a kitten. Just want o thank YT for all the useful info>

 

Ditto on that Hand tight Just untill I feel the small metal washer crush and then a 1/4 turn after that, snug enough yet not TOO snug....Man I never want to strip my threads...
