87 Pathfinder V6 - Motor surges in idle in 86.5-89 WD21 Pathfinders Posted March 6 29 minutes ago, Evan3029 said: Hello! I recently changed the fuel injectors in the throttle body as well as the fuel pump and filter because the vehicle was sputtering during acceleration. I found that after doing that, the engine still bogged down during acceleration so I checked the ecu for any codes and it threw a coolant temperature sensor code. I changed the sensor and now whenever I start the truck, it runs decently for about 20 seconds and then begins to surge while idling. Any tips on what I should do? Thanks Also, Nicoclub won’t list a 1987 pathfinder service manual. Pick the 1987 pickup truck manual. The manual will cover all the 2 door pathfinder specific stuff as well. They only made the manuals specific for pathfinder after I believe it was 1990.
