I have a 2001 expy, my initial code was p0401.....
Did what was asked. Nothing changed. Also put
on EGR valve and EPFE valve nothing changed. My
initial problem was car wouldn't excellerate, would
idle fine in park. As I put it in drive, it will act as if it
wasn't getting gas and it wouldn't excellerate as
quickly as normal. Now it's giving me 9 different
codes....... Help someone help!!!!
