[FONT=verdana, arial, helvetica]Just purchased an '03 sr5 V8 with 80,000 Miles, check engine light and VSC trac lights came on. I took my vehicle to Autozone and the guy told me that I had 3 different codes. P0102, P0430, and P0420. still looking up info on them. any one out there run across these in particular? Thanks[/FONT]

My guess would be the MAF is causing the P0102 and the other two which are emissions related to the cat are caused by the the first one. You would probably want to clean the MAF first. It is very easy and inexpensive.
