I put in fresh 5w30 Pennzoil Platinum before the motor was started for the first time. No tune revision yet as I didn't want to beat on a new clutch without getting some miles on it. This was also happening on the base tune and "final" revision from Will at PD. The tuning process was never...

So here are the updates: I spoke with my tuner and explained the problem ended up getting a retune. I was given a new base map and the car runs better and the datalogs looks better to me. This all happened today and I want to give the car a couple more days before I call it a fix. Either way, I...
I will email the tuner and see what they have to say about a MAF calibration. The o-ring had a little tear in it. I am more concerned about the MAF being crooked while it was tuned. I also forgot I have a picture of the MAF setup when I was preparing for the tune. I attached it below. Looking at...
Update, car still running slightly bad at idle but is perfect when accelerating/cruising. I attached 2 datalogs, one at idle and one cruising, and the cruising one looks like it is running excellent (to my untrained eye). However, the idle one does not. I rerouted my OCC lines so it just goes...
First of all, thank you for the responses. A couple of things to clear up: there is no difference in the tune between those 2 datalogs, just one was taken in February and one was taken last week, my OCC was set up for the valve cover to the air intake because I noticed a small pool of oil in the...
Sorry I should have been more clear. The first datalog, datalog15, is a log from about a week ago when the car was behaving OK with it slightly stumbling. The second datalog, idle1, was from final revision of my tune in February when the car was running really well. That's why I don't think it's...
Hello all,
I have been having a problem where the car stumbles a little when idling. The biggest problem is that it is intermittent. Most of the time (when the problem does occur) it idles poorly for a couple of seconds and then smooths out. Very rarely the car will stutter slightly under...
