QuestionHelp! My 1987 pick-up wants to stall out after the engine has run for ten to fifteen minutes. From my house I get right onto a highway and drive twenty miles to work. When I get off the highway, the car will die out at the first stoplight. It will turn over easily but will continue rough idleing or die out again. After taking off again from the light the truck tends to chug and hesitate whenever I descelerate. At any time, if I apply throttle, it takes off and runs great, as long as I am applying the gas.
The engine is a 22r (87 2wd pick-up, manual trans., high mileage). I have changes the fuel filter, checked the fuel pump(gas flow is good). Checked the ignition system and it all checks out, except for the ignition coil. Primary resistance is 1.0 ohms instead of the .4 to .5 ohms called for in the specs.. Checked all vacuum lines and they are o.k.. EGR checks out. Catalytic converter is good.
What parts do I need to look at on the carb.. I did check the choke already and it is working properly.
Other items of note. When it stalls, I get a strong fuel smell. Also I did seafoam the carb, fuel system and oil, to no improvement.
Any help would be greatly appreciated.

AnswerA common trouble area is the distributor, they can develop high resistance or an open circuit in the pickup coil, this is temperature related and it may be OK until the engine gets to operating temperature, my recommendation is to try to find a used distributor at an auto salvage place, you should be able to get one for between $40-50.
