Hi there, I was wondering if someone would be able to take a look at my tune and log and let me know what they think. I see based on this forum that this is a common problem but there has not been any clear-cut answer to the solution to solving these problems. I'll get random misfires and random surges and the rpms will fluctuate quite a bit.
I have tried everything as follows trying to solve this problem:
New coils
New plugs
New upstream O2
New Evap purge solenoid
Cleaned MAF and Map Sensors
Lubricated bypass valve
Valves were blasted 10k miles ago
New boost control solenoid
No change still having idle problems. 100% of the time other than cold start idles, it will idle fine and under all other driving conditions the tune is spot on. Only mods to the car are Catless Downpipe and K&N intake. Before I installed the intake, I used to be able to run no cat warmup and it would idle pretty good. I feel like the intake is most of the problem for the rough idle. I just can't figure it out. I have tried changed tons of different things in the tune to no avail. If anyone would be able to look at it and give me feedback I would be thrilled. I will post a log and my tune.
