I have an 1987 nissan pickup 2.4 it idels good and takes half throttle good but after that it starts missing and cutting out...what do u think would be wrong with it

Is the check engine light lit ? A wrench symbol light lit ? Disconnecting the battery cables is the sign of limited thinking . Hooking up a factory or professional scanner to view data an check DTC'S - diagnostic trouble code's is the first step to find the problem . Your best bet , take it to a qualified repair shop.

Throttle position switch.

If they are the same motor it fit

Mine floods the throttle body when I cut key own and dont stop till..I cut it off...

This truck has 2 ignition shstems,One of the modules is malfunctioning. follow the primary wiring from distributor to the ignition modules closeby. Disconnect one at a time untill problem found.

sounds like the throttle position sensor, I think that is the one that makes it idel rough

seems that you might have some water in the gas tank. get some gas dryer and pour in the tank. 2 half pint bottles should do to a half tank of gas. good luck.

overhaul of carb needed, check the vaccum advancer for wear n tear, rapace f necessary fo

it sounds like the injectors are not opening up man.. replace the injectores and this should fix your problem..good luck keith....

Check your intake and exhaust modules. I have a 1987 D21 and had the same problem (if I understand your post). I replaced the modules located behind the driver side headlights and it fixed the problem. Good luck! I hope this helps.
