Interesting problems we cause ourself.
Car was running fine Yesterday. I drove it prior to installing the SSI just to have a baseline feel for sound and performance. After installing the SSI and oil lines the car does not want to idle and it backfires and sputters on acceleration, up to about 3k then it takes off.
(You can review the rebuild of Years on this thread.)
