i have a 91 crx with a b16 converted to obd1 i have gotten a new map sensore rerouted it all cleaned out the cold idle vavle underneath the throttle body checked all my conections and still no luck when i start the car it run ok when its cold but not good it seems like it is missing with my chipped ecu and it idles high then drops down to low and dies so i tried another ecu a jun ecu and it revs great but still the idle problem any one know what is going on here. I appreciate any help THANKS

 

If you're running OBD-I, you need to close the FITV. I had a similar problem, 'cept it was only with my cold idle.

As for the stalling, not sure.

 

sounds like a tb leak of some sort, i have seen this but forget how to fix it already

 

I have already taken that apart and put it back and nothing it ran ok and idled good on obd0 just a little rich but now it idles like **** and runs good when im doing anything other than idling and it only runs good with the idle problem on the jun ecu odd huh?

 

does the map sensor rout differently on obd1 i have the one that came with the b16 with the sensor and 1 valve and i have an obd1 integra map with the sensor and 2 valves im using this one. also it is and xs1 motor if that has anything to do with it
