'99 some kind of ignition issue *help needed*
 

Engine starts sort of smooth, and slowly (like 4-5 seconds) starts shaking like my dog on the 4th of July. Air fuels read a solid 15.. during idle, and rpm's are normal.

This only started happening after installing ms2e, and than returning to stock ecu.

The only previous changes or issues recently: My shitty wiring when extending my 02 sensors had a short and popped fuse labeled "engine" :loser:

Everything was running fine before the ecu switching, which is the most confusing part to me. Ive done that switch several times and everything was fine. Could the ms2e somehow helped in shorting something out in the ignition system? I was thinking maybe cas or coils?

Any ideas, please?
