[JMH82SC]

Over the last month I have experienced a strange loss of power that happens for under 60 seconds or so that I hoping someone could help me diagnose. The vehicle has the stock ignition and CIS system. Vehicle runs fantastic but this problem is so intermittent I'm finding it hard to locate problem.

The loss of power feels like the lambda relay is unplugged and has a few symptoms

1 Happens most when car is idling but has happened when driving as well. Vehicle temp has no correlation as it has done it hot and cold. I have had it happen 1 mile from my house then clear up and not happen for days then yesterday I drove 25 miles and it happen on the way home.

2 Tachometer goes straight to 4 to 5 thousand RPM and real RPM would be well below 1K then out of the blue tachometer reads normal and vehicle is fine.

3 Feels like it is going to stall but you can get RPMs up and pull off the road just has no power like lambda relay and again tach is bouncing 4 to 5K.

4 I noticed yesterday when it happened the radio cut out also but I have never noticed this before.

Any direction would be a huge help.
