Camry Gen 2 series 2 Surging issue ANYONE?

[toycam88]

DOING my head in.  I have had a 92 sedan and now the 91 wagon do exactly the same thing!  Yet my 88 sedan manual I have owned for over 20yrs has NEVER done it.

Nor a 89 wagon also series one auto I had prior to these later models.

The problem is VERY specific to certain things. 

1. ONLY at operating temp (middle of guage)  2. ONLY on deceleration (touch the gas or the brake it stops) 3. ONLY at Speed range 60km to 50kmph or 1000 rpm or less. 

Its a surge, and its lunges the car back and forth. Both are autos. SO its something they added /changed in the series twos . 1990 - 1992

I will try to attach a video if allowed.  We have changed only the coolant temp sensor and cleaned the throttle body.  has anyone else had this and fixed it? 

Two camrys both doing it a coincidence ? I think its more common..and hope someone has the answer.  Thanks so much in advance.

Thank you for the chart!  We have already done a full service and addressed the plugs and distributor throttle body and airflow meter.

Coil pack was badly split and replaced as was the coolant sensor. Did a fault code reading and it come up

no faults.

Check for any damge to any vacuum hoses as well. The process can be found via Google.
