ok so i did a mpfi swap on my 91 civic got it all hooked up and running
but my ecu is showing a code 10 how to fix this also the spark plugs are black and the car is running rich i need help to fix the thank you

 

also im not getting a signal/power to my iat sensor

 

are you running the Pm6 5spd si MPFI ecu?

 

maybe you have the wrong connector plugged into the IAT sensor - the correct connector is a 2-wire, white in color, and has one red with yellow stripe wire and one green with white stripe wire

 

@ redef90si yes im running a pm6 ecu
@ jlicrx i have the red/yellow striped wire and green/white wire hooked up to it connector plugged into the IAT sensor the sensor tip is all brown does this mean its burnt? and how many volts or oms is the wires soused to put out?
thank you

 

Hopefully this will help diagnose it...

resistance between the 2 terminals on the sensor should be between 1k-ohms and 4k-ohms - voltage on red/yellow wire should be around 5 volts - green/white wire is ground

 

cool thanks the info is very helpful i will post again after i try that thank you

 

@ jlicrx thank for that form it helped out a lot got the problem fixed it was a bad iat sensor
