My 1990 Maxima has developed a terrible idle, dropping to 4 or even 3 cylinders at times with a shaky miss. This only occurs at idle. When accelerating, if you go very gentle on the throttle it will hesitate, sputter, and move slowly. However, if you employ a heavier-foot, the engine will snap out of it, and run well on all cylinders.
Once it does this, you can cruise fantastically and the engine pulls great as well. As long as you're accelerating, even if just slightly after that 'snap,' the engine purrs like a kitten.
Then, coming to a stop the engine may at first idle well. After a little time, it starts to have a miss, then it worsens and it feels like the engine is running on maybe 4 cylinders. Then, again, the heavy foot, sudden change, great performance, and back to a stop where we started.
What could be the cause of this shaky, miss-ridden idle?
Thanks in advance for helping keep a 'vintage' maxima on the road.
