i have a 91 hf crx. i was missing a vacum hose and so the idle was jumping around. i connected the hose to the correct spot and it was idleing below 500 and then would die after running for 25 seconds. i then disconnected the end of the hose that was not sucking air and it would idle at 750 and sometimes droop down but go back up. I was driving today and my check engine light came on and my car died. I started it back up with ease and pulled over. i checked my motor out and found no smoke or anything and when i got back in my car and started it no check engine light. HELP!!
