Finally got my motor running and now it's having an Ideling problem. I think that it has to do with the evap purge valve. The car is fine right when I start it up then after 10 seconds I think the computer kicks in and it starts to idle up and down a little in between 1000-1100 rpms and just keeps going back and forth. I used the obdo b16 map sensor and evap purge valve, there is a plug that needs to be plugged in, but I don't have it on my car since it's obd1. I think I need to replace it with an obd1 version??? Would there be any other reason that it is ideling high and unevenly???
