So, I swapped a rebuilt throttle body into my galant, then found that the FIAV must have been bad on it, because I had idle surge. Changed back to the old one and now she Idles fine, however I now have what feels like spark blowout or fuel cut or something around 4500 RPM when WOT. No problems when not on it hard, and when I log it, link has no data for any knock, and I have checked and re checked for boost leaks, can't hold over 10lbs but I think that is because of the compressor I am using. I haven't changed anything besides the throttle bodies, and yet have this issue. I tried putting in some fresh BPR7ES plugs gapped around .025 and that did not help.
I didn't have any issue like this before so this is something new. I tested my coil pack and harness and they are both fine. Compression is 152-157 for all four cylinders, and I am definitely not running lean...maybe a little rich if anything. The only other thing I can think of that this could be is that I jumped a tooth in my timing somehow...but I feel like I would have other issues going on as well. If that is the case, would this explain why my boost doesn't hold very well and I get weird knock when trying to tune her?
I am really at a loss here. I am going to check my timing marks on the cams in a few minutes, but figured I would post up here and ask for help for other possibilities. Mod list is up to date.
Thanks in advance to anyone who has some advice.
