engine stu...stu...stutter

NGK BCPR6ES for stock or lower boosted apps (up to say 10-12psi)
NGK BCPR7ES (colder plug) for higher boost 15+

I think you'll find that running those plugs will drasticly help your ignition problems.


Good luck and let me know how it goes (and they're cheap too), and replace them every
3rd oil change (7.5k miles, ish) for top performance.

I'll never understand how setting something as simple as a switch continues to baffle so many people. While you have it at Toyota have them look into the stuttering too because a TPS problem, especially the one you have, will definitely not cause it.
