the haynes tells me to run the engine to warm, then backprobe one of the terminals of the AAC and that i should see 4v-8v dropped. was wondering if you did this before, cause im not sure im doing it right. im backprobing with the (+) probe and grounding the (-) probe to ground... this correct? cause i'm showing a full 13...volts. also, i think i remember if you unplug the AAC while the engine's on, you should hear some change in RPM.... but i dont hear any difference now. hayne's says if the above volt test dont work, to have the ECU inspected... hmm... or i wonder if my AAC is bad?
been having loping/slightly rough idle, and so far i've come to this... although im still looking for something else that might be causing it to not work.
any ideas?
just replaced:
some hoses - no leaks that i can tell.
fuel injector - no leaks external or from O-rings
PCV valve
plugs - NGK (show slight whitish color, base is dry black)
Oil flush
