Someone suggested CTS sensor since it only happens when car is warm. maybe I could fool ECU into thinking car is still cold.

Here are the results:
Well well Iive and learn . First I found the CTS sensor and when I looked at the wiring I saw some wire was exposed and the black covering sorta crumbled a little more as I handled it.

So much for the condition of my upper harness ( I think ) . I proceeded to take connector off engine with engine off , temp approx 95C pre disconnecting it , restarted and drove it around a little . No difference . Engine missed at the same RPM 1400-1800 under hard acceleration. Feathered throttle produced no engine miss as usual

So then I turned it off for about 1 1/2 hours to cool down and retry. When I started it again the K6JRF view in the climate control window on position #6 said LOW instead of a temp.

But the instrument cluster showed the temp approx 65C. Also the instrument cluster temp gauge got up to over 80 C in city driving , and back down to 70C on the highway . When I first start in the morning the cluster gauge shows below 40C and at that temp it never misses .

Now we know that the car has 2 independent engine coolant temp sensors. EUREKA

I left the sensor disconnected and drove home.
The miss/bogg was still there. Nothing seemed different at all ! Actually after a half hour of highway driving , and slowing down to 40 MPH and 1700 RPM an attempt at rapid acceleration without a downshift caused the famous miss/ bogg 2 more times and one time I was going slightly downhill.

The longer the engine is running regardless of temp at the moment , the more likely the engine will bogg down.

I am going to let the car cool down entirely overnight , so that I know I am at the same starting point and drive the car tomorrow,let it run 30-60 seconds , and see if it STILL NEVER MISSES COLD, and at what temp it will start to miss when warm as usual , with the CTS sensor on the engine manifold disconnected .

I am also going to build the code reader this monday
