Nissan Repair Questions? Ask a Mechanic for Answers ASAP
Hello Bill, my name is ***** ***** thank you for your question.
There could be a few things going on here. First I need to ask some questions to possibly understand everything you are dealing with.
When you get this surging, do you find it does it when going up a hill or under heaver acceleration? But if you lightly accelerate it's ok?
Also when you see this loss of power do you watch the RPMS? and see it fluctuate? or Surge up?
Do you have a Check Engine light on when the van is running also?
Let me know..
