    I just did the obd1 conversion and car runs fine, except when im slowing down and let my foot off the brake, the idle goes between 1000-2000 every few seconds. ANy idea what could cause this and is this really a bad thing?

    It won't hurt anything...

    Have you checked you IACV? Are you getting any check engine lights???

    That happens when the ECU is struggling because there is too much air entering your engine. Probably a vacuum leak somewhere. Does it do it all the time? When the engine is hot? Cold?
