Hi guys, can anyone shed abit of light on what an error 42 could be, with a '98 VT?.. know it means "electronic spark timing bypass circuit" which means????????????..Its just recently been serviced and the engine warn light started to come on and off just after that(AS they do :-S) It doesnt come on all the time and does go off at times by itself while driving and goes off and stays off for awhile if you tur the key off and restart.
