i was driving normaly on the freeway until it was headed down a down hill so i putted the car in neutral and letting it roll, next thing you known my car revs up 1-4k rpm by it self up n down!... i putted a metal piece into my ecu thingy and see how many times the CE light blinks and it blinkd 5 times.. anyone have ne clue?

 

HELP!!!!

 

Are the vacuums hooked up to the map sensor?
?
Is it 5 constant flashing or a space in between

 

Short blinks or long blinks, short stands for 1 long stands for 10.

 

Had similar problem, replaced the IACV and voila, problem solved.

 

it blinks 5 times one after another.. 5 times.. then a pause and 5 times again...
