My 1990 integra is not running right at all, it has no power, while sitting still it idles like crap, and when the throttle is opened to the max is sits at idle and will slowly creep to about 2000 rpms, then it takes right off, but while driving the car has no power an wont even get up and go to take off. Whats the problem? every now and then the check engine light comes on, and the ecu light flashes once fast, then once slow, and thats it, is that a CEL code 1 or 11?

Please help....
