I have a cheap one, not sure it shows fuel trim. I don't have any pending or logged fault codes.

Hey!

I'm glad it worked out for you (although changing the timing belt was troublesome for you). I keep getting the same P1351 error, and I think I must replace the timing on mine too, to finally get rid of the error and occasional vibrations.

My 02 ES300 has 194k miles on it and the timing has never been replaced!!
