MY 92 350L THAT WAS REBUILT LAST SPRING SEEMS TO LOSE SPARK UNDER A LOAD WHEN YOU MAX OUT THE THROTTLE. DOES THIS SEEM LIKE COIL OR ELECTRONIC THROTTLE CONTROL PROBLEM? SEEMS TO ONLY DO IT WHEN ITS WARM AND UNDER LOAD THANKS FOR ANY HELP

 

welcome tot he forum. cap locks not needed though lol. when you say loose spark, does it shut down, turn off or back fire. what makes you think its loosing fire? is it only under full throttle? if it is actually shutting down (no fire that is) it could very well be a hot coil breaking down since it does it when its hot. give a little more info on what ity does so the guys can give a little better help.

 

Sorry about caps but I'm a one finger typer and its eaiser plus i'l old and bad eyes.
yes it sounds like it just shuts off but only at full throttle posisition and when warm. does anyone have the resistance readings for the coil? thanks hope this helped
