1987 Nissan: 4wd..pickup..The engine surges at idol..dealership

This answer was rated:

I have 1987 Nissan 4wd pickup. The engine surges at idol from 250 rpm to 500 rpm. I took it to be worked on... To make a long story short - The dealership made it worst - Not better. They replaced the computer - It is fuel injected 4 cyl.

First of the the min idle is set too low. Does the idle control work. Vaccum leaks.?

1. What is engine Vacuum at idle 18 inches are specs'

2. What is ing timing ..

3. Are there any codes/

 

Check those and get back to me.

 

My advise is why did the dealer change the computer? If it was to fix you low idle then they need to it back in their shop.

 

Let me know. Jim

 

This should be more info needed not an answer..
