Hey guys, not sure if this is even in the right spot but anyway, been having idling problems, horrible idle and misfiring after taking airbox out to clean and replacing air filter. I haven't missed anything, I've done it countless times before so I thought maybe someone on here may have had a similar experience. I got a code 24 for iacv but after cleaning it out and testing for leaks around gasket have found that not to be the problem. I have replaced maf to no avail. Running out of ideas, can post a video if needed Cheers
