k so i have a jdm motor, just put a mhg on it. got it put back together and it ran for a couple of days just fine. then about a week after it got put together, it started running really bad.

i believe a few cylinders are out. i have checked spark. and i have 120 for compression on all cylinders. all intercooler piping is hooked up, and my afm is good.

if you know anything that i could try please let me know. i have a race this sunday and would love to go.

how is it running bad? does it feel like it's missing? any knocking or any kind of other noise? hesitating? BTW, compression is supposed to be around 142 for a good motor.
