Misfire at wide open throttle
Posted by 02Viggen [Email] (more from 02Viggen) on Thu, 24 Oct 2019 20:05:48
My Viggen has developed a misfire at WOT; doesn't matter what RPM it's at, just when it's at WOT. When it happens I get a loud "BRAAPPP" misfire sound out the exhaust accompanied by a cloud of dark/black smoke that I can only assume is unburnt fuel. This is not producing a check engine light.
I'm suspecting my DIC, mostly because it seems like an ignition issue, and they aren't the most reliable part. It's 3-4 years old but maybe has only 20-30k miles on it, and it is a Genuine Saab part.
What do you think?
