Ok some time ago my car stopped running well every day. (march) By that I mean I would not idle were it was supposed to. Stall or stay at 1500 all the time. Some times it would be fine like 80% of the time. Time gos past my hg blows and I replace the Iac and the wiring harness going to it. It works ok and then idles too low and then too high. I just installed my map ecu 2 and I still need to get it tuned but can I delete the iac. I know one of our vendors makes a block off plate but how will I get enough air to make it idle? Plz help me with this. Im soo tired of this idle issue the stalling and bs.
