i have a 93 ls400 and its been giving me some issues... i found that only the passenger side dizzy sends spark and so i got a driver side coil... now im having issues putting it in and im not even sure if thats the issues but im going crazy not driving my baby... it sometimes acts like it fires the driver side coil and sometimes it doesnt... sometimes under very light throttle its ok... but step on it and it has no power... its even harder to rev with the ac on like there is absolutely no power... could it be the igniter or was i right in ordering a coil?.. any help would be very helpful
