Well i bought a del sol and it has a D15B7 in it and I have two problems:
1. It is throwing code 3 wich is of course the map sensor. i went to look for it and its not on the firewall or the TB. so i bought a new one at autozone but need the the connector (no where to be found!?!?!) Where can i get it?

2. the car idles at 1500-2000 rpm but it is not throwing a code for the Idle control valve. i disconnect the control valve and it drops to 750-800 rpm. I tried to set the idle they way it is instructed in the chilton manual but it still idles high. is the Idle control valve bad ? Dose the MAP sensor have anything to do with it?

Any help is appriciated.

 

anyone?

 

did you ever figure out what the problem was? im having the same problem with my 91 crx with the d15b7 motor in it. when i start it, it jumps from 2k-3k rpms then a check engine light comes on then shuts off

 

Did you take the iacv off and clean it, also don't worry about the idle problem until you get all your cels off. Like the map sensor. Same thing was happening to me but it went away once i fixed the cels. WhitterJohn have you gotten the code, that would be your first place to start, your ecu should store the code even when the light is off.

 

well i had got the high idle problem fixed just now it wont stay at idle unless i give it some gas. but check engine light kicks on after about less than a min. on my car its all obd0 and i dont really know how to read the code or anything like that.
