apologies for this long post, just had no idea how to describe this in 10 words or less also i've searched the forums forthe last 3 hours and couldn't find anything that matches my problem(s)
firstly, some history on previous problems.. when i first bought this car (about 3 years ago) it had a problem with the ICV. i cleaned it out and all was fine for a long, long time. in the last few months though, i've found error codes 57 (ICV - interruption) & 87 (aircon cut-off relay low voltage)
now i'm not entirely sure what the "interruption" error means - can anyone explain what this means exactly? the aircon cut-off relay - where is this relay? which one is it exactly? and what would the symptoms be as everything to do with the aircon seems to be fine?
i haven't experienced the "usual" ICV problems (cutting out when coming to a stop, etc) but i have had a problem where the car would open throttle on it's own for a couple of seconds, then the EM light comes on and all is fine again.
starting this morning, however, this open throttle problem has become a little more persistent in that the car no longer idles at normal RPM (900) but bounces between 1500rpm to 2000rpm+ and the EM light is permanently lit. this happens constantly. when car is still, when cruising, no matter what, it opens throttle for a few seconds up to 2000rpm+, then drops to 1500rpm and bounces back up again.
