Car is running a OTS map from Matt Miner.
Has a SPT cold air, GMS cat back, CNT high flow catted downpipe. That's it for tune mods.
Hey all, have not posted on here in a while. Around a year and a half ago I bought a 09 LGT MT. Come to find out a month or two later the motor was no good, I was also getting consistent knock when going up hills? bad compression around most cyl with 4 being the worst (60 psi). Luckily I found a motor at my job where I went in blind with a leak down tester (didnt know what i was doing. ) But according to the directions the motor passed the leak down test. Fast forward today, I've put the "new" motor in. I did a cold compression test after driving it for about a week. All plugs out, with throttle down and the lowest cylinder being 113, the highest being 118.
I still have been having this consistent issue that I was having with the last motor. My feedback knock will jump around when I am going up hills.. It happens A LOT in 3rd gear as well, at full throttle going uphill. Rarely does it happen when I am on a straight or down hill (sometimes it happens in higher RPMs third gear?). I do not see knock in 1st or 2nd gear at full throttle ever.
Today my dam dropped to .75 and back up to .875 a few seconds later.
The car has pulled great, it idles relatively well. Sounds like an average boxer. Haven't heard any audible knocks. I put group n motor mounts in, did almost all the gaskets on the motor.
I genuinely do not know if the motor is junk and my warranty is going to end soon. (id assume my work would help me out but better safe than sorry.) I have been consistently trying to find the problem, with motor mounts. loose things under the hood, vacuum leaks, pcv. I have zip tied everything. I also feel like most of the 3rd gear knock happens around 80 mph. The car has an AWFUL power steering rack, and a god awful alignment. At above 75 the wheel will be shaking pretty rough. The rack I have not replaced as I don't want to invest much more till I know it is worth it.
I'm going to leave some logs, but bare with me I have never put logs up before and don't know if I was supposed to shorten anything. Sorry for this being all over the place.
-2.8 knock (the most consistent one ive seen, usually stays while im on the throttle going up hill.)
