I've noticed a problem in the last day with my 1989 CRX HF. I finally got the idle right, and it seems to idle somewhere around 750rpm. I was driving it back from my friends apartment and the car suddenly wouldn't stay idling anymore. If I was driving and pulled up to a stop sign and pressed in the clutch or shifted into neutral, then engine would idle down to about 1000 rpm, then it would idle up to 1500 rpm or so, and then it would drop off to zero and stall. 9 times out of 10, I can just refire it, and it will stay running, but then it idles somewhere around 250 rpm or so... practically stalling. 1 time of 10 it won't fire back up for me. At least not right away. To restart, I just bump it with the clutch if i'm still moving and it usually comes right back. Once I wasn't moving very fast and it wouldn't bump right away, and wouldn't start when i cranked it. I got out popped the hood and sat around for a little bit, and then it refired right away. Two other times that it's (not refiring) happened, I was moving fast enough that I could keep it in gear and just keep the motor turning over. Eventually (10-15 seconds) of coasting in gear with the motor turning over it will refire. When it's coasting and not firing, it almost feels like it's bogging because it seems to respond a little to throttle input, but it's like it won't quite take off. I really have no idea what could be causing this. Maybe running too rich? I the CEL isn't on either.
