Also check the fuel return lines between the injectors. Any leaks can allow air in, and that can also cause a miss. A compression test is a good idea. It may have a stuck or broken ring, especially since it sat so long.
How does the engine run at normal operating temp?

The car does not have the cigar return line and I was wondering if this can cause issues?
It runs near perfect cold, as it warms and coming off the freeway it starts to shake more, if it were a high lift gas motor it would be cool. The other thing I notice is it will run good from cold until I get on the throttle and rev it up then the miss starts.
I will replace all of the return lines this weekend, there are no visible leaks but they are the original and it starts like there could be air in the injectors thus air allowed in the line but no fuel leaks out.
Now I'm worried this car is going to self destruct from sitting too long! That sucks because after 1000 rpm it is so smooth and quiet and running down the freeway at 75 it just hums perfect.
For the best part of the story I traded my buddy my other car for a HK USP 40SW and he and I installed my spare good engine me keeping the engine with the slap in it. Well we had one heck of a time doing the swap and he was regretting the trade. His car(my old one) is running great and he has become a 126 300SD fan after driving it in the mountains and now understands why I go to all of the trouble to get them going. He can't believe the car get 23-25mpg no matter how or where he drives it. Plus the car drives and handles so much better than the 240 he bought before this one. He actually said it is hands down the best driving/handling car he has ever owned. Now I'm regretting the greener side of the fence.
