88 2nd gen convertable. New to the 13B. Agrivating flutter between accelleration & decelleration. Where to begin looking???

 

Turbo II???

 

Welcome to the forum.

Right near closed throttle, the ECU cuts fuel to first one rotor then the other as it thinks you are decelerating.
If the cuts are too harsh, you may need to readjust the TPS.

 

Non-Turbo. I'll start researching the TPS. Really appreciate the response.

 

I see the throttle sensor calls for a tool "Checker Lamp", part # 49 F018001. Is this something that can be simply made? Am I on the right path? Thx

 

There are 3 ways to set the TPS.
1) Use a test lamp
2) back probe the voltage from the sensor to set 1 volt at idle.
3) My favorite - unplug & clip an Ohmmeter on the sensor.
Unplug the TPS connector.
Clip a cheap analog (needle type) VOM on the orange & black pins.
Set it to the 1K Ohms scale.
Hold off the throttle & work the short range TPS plunger in & out.
You should see a smooth sweep from ~0 to ~5K ohms.
Any bad spots or drop outs in the stroke - it's bad & will give fuel cuts at part throttle.
(Before you toss it, try spray contact cleaner between the sleeve & plunger.)
- Then set it:
Find the fast idle (warm-up) cam & push it back so the throttle sits on the hard idle stop.
Adjust the setting to 1K ohms.
While holding off the fast idle cam, open & close the throttle a few times to see that the 1K setting repeats.
