leaning could be caused by many things.. dirty injectors, clogged fuel
filter, all sorts of fun stuff which wouldn't be likely on a '99 model
truck... I know the colder thermo helped out my pinging, as did the elec.
fan and pulley, which just took load off the motor, thereby not making it
work as hard.
Has the dealer preformed the wire reroute tsb on your truck?
