I have a 2003 Caravan that runs great, except when you kick it in passing gear. Then it completely cuts out, let off the gas some and it runs fine again. I changed the crank and cam position sensors because their codes were coming up, but I still have the problem. Any ideas?
In addition to the clogged cat, what about fuel pressure? Had a vehicle that when you floored it, it would stall out as pressure was too low. Once the regulator was swapped, the problem went away.
