Message Hi guys,

I have an issue that is really weird and might be related to the speed sensor, because I have the speedometer issue and someone unsubstantial issues related to that.

SO here is the issue. As I am crusing my car will randomly ignore my foot pressing on the pedal.

I can feel the car jerk (like downshifting) and the pedal will no longer respond to the pressure of acceleration. Then it kicks back in - out - in - out.

or I can get it to kick back in if I shift out and then back into gear.

Double Tap the the Clutch or Tap on the gas a few times.

I also noticed that the car does not start right away. Ususually after the second turn of the key or if I press the clutch down twice before turning the key.

Should I try replacing the Speed Sensor first? If, so When can I find a twin turbo speed sensor replacement.

I hope that explained it well enough. I also had Nissan take a look and hook it up to a computer. They didnt see anything and I never get a check engine light. I do sometimes get a HICUS light. Not not often. It the problem is more intense when it rains / or is raining.
