I know this has been discussed in many other forums ad nauseam, but I have not come across a hesitation thread that describes the symptoms of my particular problem. I have a 93 convertible with 54k original miles on it. the car is all original except for the wheels (350z 18 inch wheels). I have a hesitation between 2 and 3k RPM. Here are the details:
  • The car runs fantastic when cold, with no hesitation in any gears or RPM.
  • Once the car is warm, the hesitation is in first, second, and third gears.
  • In first gear, it is a slight blip between 2k and 2500k
  • In second gear it is a bit more pronounced above 2500k through about 3k
  • In third gear, it is very similar to 2nd gear but closer to 3K RPM
  • In fourth and fifth gear, the car seems to run normally through the entire rev range.
  • After 3k in all gears, the car runs normal
  • I have replaced the fuel filter, spark plugs and coil packs.
  • I have cleaned the plugs to the AFM, Temp sensor and TPS.
  • No CEL on the dash, ever.
I do not want to cause any issues with the electrical system, so I thought I would post here to see if anyone can help me narrow this down. Diagnostic on an issue like this can run into the thousands because I have found that none of the dealerships around me have the Nissan Consult system. If I can narrow it down, that might help offset the cost
I am sure this is a simple fix; it is just a matter of figuring out the quickest way to determine what is at fault.

Any help would be greatly appreciated.
