(Seat Ibiza 1995 6K 1.4 ABD) This has happened before, and I've replaced the idle air control valve 051 133 031 with a second hand one about two and a half months ago, it was actually the fourth one that worked, we unhooked the battery overnight, and let it learn to idle tomorrow morning. It was way better than before, not to mention the self-destruct mode the engine apparently initiates has actually stopped. It happened to me again today and I don't know whether to replace it with a new part or remove it altogether and make it cable operated. - Can an IACV even rev an engine to redline? I rely on it every day, and use it for up to 20 miles per day of city driving, and it is what it is, an old car, and if I could I'd just get rid of the thing, but due to my current situation I can only afford cheap/DIY fixes. I've seen a brand new BOSCH IACV which is expensive, but there's also one made by "ERA Automotive parts" - it's 80% cheaper. Can anyone give me some advice on how to proceed properly? I am just so paranoid now, that I think not even new ones would solve the problem. Maybe it's not that part, maybe there's something else? Thank you everyone in advance!
