TPS Problem B18C1GSR

[Kyle Peterson]

I have a 91 crx with a B18C1
I’ve been having an idle issue, when driving and giving it gas it’s runs great, but when at idle at a stop light, the rpm with dip down to where it’s barely running, and sometimes it’ll idle okay but if I give it a little gas it’ll dive back down and barely run, I tried recalibration good my tps sensor, but I can’t get it to pivot enough to get it into spec (.45-.5v) I ended up cutting the sensor so it could pivot more and got it in spec but I’m still having the same idle problem. Any ideas?

Sounds like the Idle Control Valve is faulty / dirty. I think Honda calls it he Idle Air Control Valve – search for video on cleaning / replacement.
