I have not driven my car in like 2 months, due to a broken left ankle, and an annoying idle. We have tried everything. I put another iacv on, i have adjusted the idle for hours, I have messed with the smc to see if the fuel was causing the problem, no luck with any of them. Would a bad ecu throw a code? I found a new ecu for cheap, and I thought what the heck. Should I try it. What else could it be. As soon as he ankle is healed (3 more grueling weeks in a cast) and I get the idle problem solved, then I want to go get tuned. Any help would be appricated.
