It started and idled pretty well, didn’t really notice until I hit the gas, and I could really notice the miss. I swapped it out with one from advance and it’s been flawless since then.

I tried to check the mani but don’t think i found any cracks, i cannot hear a leak at all and i have the shitty california emissions bs where i have four 02’s and tw osmall cats on the mani itself as well. As far as power lose it does not feel like it at all nor does it have a miss, at idle it a tad jumpy and rough though.
