Good day. My lexus rx 330 had an over-heat last 3weeks, i took it to the auto workshop the found out that one of the fans isnt good hence causing the over heat as well as damaging a water hose/pipe. 2 weeks after all this ve been changed and fixed the car was up and runing again, i realised that the car miss-fires. I took it back to the auto work shop the discovered that one of the coils is not functional and it was changed and all was fine. Few days later same thing happend, another coil dead!! And it was changed. Now another coil (3rd) is not working again!!
Pls auto gurus, what might be the cause this? I need an advise. Thanks

Firstly you should have scanned the car cos the first one might bring a solid code and the rest will be pending.. what I’m trying to say is that once one coil gives up, just change it all because there is a chance the rest might go bad soon which happened to you. So if you had scanned the car you will get a solid code for the first misfire and the rest pending so you would have changed all at once and save yourself this stress of changing it one by one... Try scanning the car
