Isuzu Repair: pup erratic idle, isuzu pup, vacuum problem


Question
I own a 1987 isuzu pup 1.9L.  I am having an issue with the idle at various times and conditions.  The choke works first thing in the morning to start it up and will kick down when needed.  Drive it and go to a stop sign and it might die.  Then get to babysitters house and it might die, start up and idle might be high.  Then after driving it to normal temp, the idle seems to be way to high and sometimes when you try to kick it down it might just die or not go down.  On occasion it idles normal.  I have sprayed all the linkages down and moved them around but has not helped.  Any ideas?

Answer
Hello Landon, Well, it sounds like a vacuum problem, fuel filter, fuel pump not working properly, or your throttle postioning sensor is on apple whacky's. I would check this. also check your starting and charging system connections and battery cables.
