ok ,,update the truck fires but wont stay running ,unless u hold it to the floor basicly and it acts like its straving for fuel,spark is good,im running bosh platium {2} 4 of those and plug wires are good and distrabtior is good didnt touch it, i changed the fuel filter,my friend says there are like 4 sensors and it might bve different wiring so hes goona re wire or cange each sensor so what do u guys think?
