Hi everyone. I just moved to the NorCal area (Sacramento) from Colorado, and through the entire 1100+ mile trip, my car was running fine, nothing was wrong with it that I could tell. Soon as I came down the mountain from Reno, the car started shaking really badly when I try to accelerate. Sometimes it shakes harder than others, and if I baby it it shakes a lot less. I tried taking it to a local mechanic and they couldn't help me at all since it's a swapped motor. If anyone can give me pointers on what to look for, or a shop around Sacramento that could help me out I'd greatly appreciate it.

P.S. It's an EG with a H22 in it.
