I have a 2006 Toyota 4 runner. 2 wheel drive with the v6. It has a 430 and a 420 code. The 430 code has been there a while and the 420 code popped up recently. The vehicle has also started shuttering when driving between 35 and 45 mph. Any advice on which direction I should go and the steps I should take to resolve these issues. And how likely related they are to each other. Any tips or recommendations for saving money would be perfect as well. Thank you in advance.
