Probably just got used to it. I know the limg was replaced with the newer style so I'm good there. I was actually planning on doing a leak down and compression test tomorrow at school since it's a task we have to complete anyways. Might be because it's such a large car compared to my alero it just feels slower. My AFRs were checked a few days ago and they were right on the dot. My rear o2 heater is shot, but that has nothing to do with engine performance. Maf checked out good along with a few other sensors. I noticed though when I start it up hot it'll lope a few seconds like it's cammed up.
