Race car mystery-Help us solve PLEASE
hmmmm no ticks or misses.
double and triple check this >>>
sometimes new parts work good then slip out of adjustment when they break in. maybe one of the lil springs jumped or streched or somethin weird inside. i dont think it would make it miss but maybe just lose a little oompa
also is it electric water pump or belt driven? could be draggin if it's belt drivin. same with alt. you might have to pull the belt make sure stuff isnt binding. also a weak coil. but you cant really test them without a swap. dont try the manual test method lol
