The TT is having some cold start problems. it stumbles badly on start up.
I am looking to replace the plugs tomorrow, and would like to try NGK PFR6Q instead of the Iridiums which i have used over the last 3(?) changes.
What should the NGK plugs be gapped to .32 or .29?
TIA

I have the Ik22s. You need to check the gap as it tends to increase...>>
I have mine at 0.30" I was having the same problems. the had increased to 0.40" over 10,000 miles. Reset and no more problems. I now check them every 5,000 miles when I change the oil.
Hope this helps.
