Okay...i've posted something like this previously. It's happening again, more often. Funny thing is, when we pull up the codes on the Tech2, there AREN't any. Everything just "looks" fine. I use a 12gal to 6gal blend of 100octane to 91octane and change oil religiously on time. I'm currently running M1 10W-40 full synth. I'm thinking DI cassette starting to go bad...any of you have any thoughts? Anyone ever experience the same thing?
