Isuzu Repair: isuzu, fuel system, fuel pump

Question
my 1988 isuzu will not idle until it warms up , and then it bogs down when him accelerating up a hill or incline . it seems to do it more when I'm about 3/8 of a tank or lower of gas.it doesn't do it on every hill but more times than not.

Answer
Well I would highly recommend having your ignition and fuel system checked. It could be something as simple as an fuel/air filter or the fuel pump but I would check the ignition and fuel system and tell me what you find okay? Your timing could be in need of some adjusting too.
