Trying to help a friend with his 2007 F8. The sled will flash check engine light and throw out a code 18
( servomotor ) then run very rough. He would then turn the sled off and restart with the code going off for 15 or so minutes with the sled running normal. Then the sled would start flashing the code again. It did this for awhile and now the sled will not start. He had similar issues last year and had to replace the ECU. Any info into this issue would be appreciated.
Thanks,
