The codes flashing on my ECU are "7" (Throttle Position Sensor) and "9" (CYP sensor). I'm not sure where either of these sensors are yet. Does anyone happen to know? (B16a)

The car has been running a little rough lately, kinda sporadiclly. Seems like it's missing. I'm not sure if a cap/rotor/plug change would cure this or if it's because of one of these sensors.

 

Those two codes are contributing to the problem. Either pick up a Helms manual and try and fix the problem yourself or take it to a shop to get it fixed.

The CYP sensor is inside of the distributor and the throttle position sensor is on the front of the throttle body.

 

Thanks Shmoo. I have to put this project on hold for a couple weeks but I'll swap out the sensors and see if it solves my problems.

The car starts and runs fine but I'll be driving down the road and all of a sudden it starts to run rough, like its only running on 3 outa 4 cyls. If I downshift and give it a little gas, it runs great again until I get off the gas and drive at a steady pace.

Usually after the engine warms up, this problem goes away. I've also noticed that it does it more often early in the morning or the first time I drive it for the day, but never in the afternoon on the way home from work. It doesn't do it every day either?!?!

 

Yeah, it does sound like a problem related to the sensors. It may not be necessary to swap them out, though. Pick up a Helms manual or find an online service manual to help troubleshoot the problem. It may be an issue in the wiring, not the sensor.
