so my son has a 02 24 valve atuo. the motor has about 400 thousand on it still runs strong BUT his mpgs has just took a dump down to about 9 . any ideas ????
he does have a chip I think it is called the puck. could it have gone bad ? he does know that the turbo has a little sloop in it. maybe ??he needs HELP
Try running the valves and change fuel filter(s). Also might be the injectors if they are stock or have alot of miles on them. If it is the power puck just unplug it for a tank and see if that is the problem.
