so I have an 88 crx dx with a b18a1 in it. Took it in for emissions testing, and failed horribly. Car seemed to be running really rich(really high CO, somewhat high HC), so I replaced the o2 sensor with a bosch unit, and some other stuff. Shortly after(about 4 miles), the cel came on, coming up as a #7. #7 is the throttle angle sensor. The car runs fine, just has the cel. I tried to reset the ecu to no avail, and just a moment ago replaced the tps. The cel is still there. Any other ideas what I should check?
