is there an idle relearn or something that need to be done after the injector swap? I just did mine and it idles at about 12-1300 instead of 750 or so. I took it all back apart and checked o rings and seals, can't hear a vacuum leak..

96 cherokee, 4.0

 

Thats what it soulds like a vacuum leak. Take a can of brake clean while the motor is running shoot some around the O-rings and if the idle jumps or dies there's your leak. Maybe knocked a vacuum line of to. Just double triple check everything is in place.

 

 

when you installed them did you reset the cpu by touching the positive and negative battery cables together when off the battery?

 

Nope, sure didn't - I'll try all this thanks guys

 

where did you learn that

 

tried it just now - didn't help. I have a check engine light now so maybe that will give me a hint.. Tried throttle body cleaner and brake clean to test for leaks, honestly I can't find one..

 

+ anyone know how to get the ses light to blink out codes? i'm looking for it but you might be faster

 

ok. got a scanner to see what the code is?

 

umm I know it's floating around the tech section somewear..

 

no.. isn't there an ignition or pedal dance you can do to make it blink them out?

 

got it.

the only one it blinked out that isn;t 12 or 55 (battery disconnected and end of codes) is 25:

25 Idle Air Control circuit (IAC) Check IAC sensor and wiring.

 

coincidence? it just goes bad at same time?
Yea check the wiring.

 

that little guy was just barely moved out.. snapped it in and I'
m all set thanks guys
