I have had my engine light coming on for bout 6 months now and its getting progressivly worst,wierd thing is that it only comes on at about 1500 rpm and up anything below that and it wont come on,but all it does is blink and not in any order either.the car runs fine no problems i also hooked it up to an OTC computer and there were no stored codes was wondering if anyone else has had this problem or any idea's thanks guys
