I borrowed my brother's torque wrench to do my spark plugs correctly... and blew it! I set the torque, but it did not click, and I think I totally over-torqued one of the plugs. The other 3 I just tightened with my normal ratchet, probably tighter than spec.
So... what do I do? Do I back out the plug and re-tighten, or just leave it until the next plug change? I've had to drive the car since... No idea what is the issue with the stupid cheapo torque wrench (probably Harbor Freight or something...) I've tried it on my wheel studs, and again, it did not click! I had borrowed it previously, and it worked.
I'm worried that I might have damaged the threads, and backing it out may reveal the damage, vs. leaving it in (car is running fine).
