I have a 1991 civic hb the motor is stock it is a daily driver. Now it was throwing a check engine light fixed all of them but now the car will start or turn over and run at about 2,000 rpm's and idile down and 1 die or if I give it gas it sounds like it is chokeing the motor all with in 10 - 15 seconds. The motor ran with the check engine light on now it won't stay running.

 

Look at the ECU and see if t is flashing a code. It is located beneath the passenger side foot-area carpet.

 

Here's the chart on how to read it:
