I still know very little about the changes that occured in the wrx/sti (and other cars) since my car was created...

Do DBW cars still have an IACV, and if so why?

simple question, hoping for a simple answer.

Just installed a new sf stage 1 intake and access port from Cobb, also put brand new denso maf in as-well. Flashed the ecu to install the ecn91 stage 1+ tune and car will barely start. Tried a couple times and nothing happens except the engine sounding like hell. Let the car sit for 30 min came back looked at vacuum pump and then unplugged/ replugged the maf and car started up. The idle was still either high (1500rpms) or low enough to stall out. I revved the car a few times to see where the rpm’s would land after and it went all the way to 0 back up to 300 then stalled out. So my question is, where do you buy a good dependable is v lol🙂
