When I go across bumps ,like speed bumps,the truck acts like it's running out of fuel.it only does it when it rocks back and forth kinda quick like.not very many of these side to side bumps do it but it could get dangerous.only does it from 0 to about 10 mph,like when pulling out on the hi way.the other day it actually kinda backfired and sputtered .this has been going on awhile.so I pulled the fuel tank and it's clean as new money.its a 99 and has only 15000 miles on it so I don't think anything is worn out and it runs as good as ever.
Sooo,any ideas as to what could cause this?didnt know if fuel inertia switch could cause it but it's never actually tripped.
