GSR swapped 1990 Si coding CEL #9
So the car was converted to obd1 and was running fine for about a month. Then a check engine light came on one day when I started the car, it came on almost immediately. I have observed that upon start up the cel with stay off, but when I go near the throttle it bogs a little then the cel appears. The car runs and drives fine for the most part. Sometimes the idle will surge, but this is very intermittent. I checked all the connections and plugs from the distributor, and the distributor is new.

Absolutely brand new. With the exception of about 2500 miles. The plugs are the same, brand new 2500 miles ago. The only thing that is questionable as far as I saw were the wires, they are ngks in fair shape but I never replaced them.

Follow the trouble tree! haha
wow, how many times am going to have to post this..
its the cyp sensor, cylinder posistion sensor
PURPOSE
To determine ignition timing at start-up, position of #1 cylinder for sequential fuel injection, and normal timing for fuel injection and ignition of each cylinder and also detects engine RPM.
OPERATION
The Engine Control Module (ECM) uses these signals to determine fuel injector and ignition timing and to calculate engine RPM.
The Top Dead Center (TDC) sensor signal is used to determine ignition timing at engine start-up. This signal is also used as a backup signal in the event the Cylinder Position (CYP) sensor signal becomes abnormal.
The Crankshaft Position (CKP) sensor determines timing for fuel injection and ignition timing of each cylinder and detects engine speed.
The Cylinder Position (CYP) sensor generates a signal based on the position of the number #1 cylinder for proper timing of the sequential fuel injection system for all cylinders.
CONSTRUCTION
All three sensors are pickup coil and reluctor construction. The sensors cannot be serviced separately.
