Re: 99 Toyota V6 with 135k miles and 9 yr old TB with 50k miles.
Splain this one. With old belt LTFT was consistently +3-4% on Bank 2 and -5-6% on Bank 1. With new belt, LTFT is close to zero on both Banks. In fact, I checked after running errands this morning and LTFT was 0.0% on both Banks. Old belt looked perfect except it had stretched a little. Why did new belt improve/balance LTFT's? Thanks.
