90 legacy running rough

Featured Replies

i have a problem with the legacy and i'm stumped. went to leave work today and when i fired it up it began to run really rough. the check engine light also came on. so i drove it home and it's low on power and sputtering badly. so i had to keep the rpm's up to get it to highway speed. got it home and pulled the codes and i got this

11- crank sensor

14- injector 1

15- injector 2

16- injector 3

24- air control valve

 

i disconnected the battery to reset and without even starting the car i still get the same codes

what i don't get is it ran fine up to the point when i shut it off this morning and now its acting like this.

anyone have an idea about this?

Check for power to each injector. you may have a broken wire at a crimp joint.

 

I'd advise removing and cleaning out the IAC as well. IAC problems will force the ECU to cut fuel to #1 injector in attempt to control the idle.

do i do this with the car running or not running

 

even if the iac needed cleaned would that cause problems at just idle or all the time.

Not running. Should be voltage even with key off.

 

IAC codes can play hell with the injectors. I HATE that they are tied toghether in the software like that.
