Spark plug

This happened to my car. every time the AC came on she stalled. So I removed the AC fuse and she runs fine. I don't really need AC where I live rarely gets warm and if it does I open the windows lol...

Did you bleed the cooling system? mite be air locked...

Helogen bulbs last a long time if you buy good quality ones. I used to taxi and they lasted for years. my mate had a BMW at the time and replacement Xenon bulbs were a £180 each. Much easier to find £10 or so then £180...

Mine was damaged in 2010 and repaired by Lexus. The bill for it is in with the service history. They did me a favour then lol.. Halogen bulbs are so much cheaper to replace when they blow...

Mine has normal Helagen bulbs. Not sure what year they changed to the deerer HID bulbs...

I don't see why you can't use a cleaner disc. I always had more success removing the top cover and cleaning the lens with a cotton bud with lens cleaner on it. Not sure tho' how to remove the player on the Lexus like on older cars that was easy to remove with pins... Maybe someone else on here can help on how to remove it from the dash...

Removing the battery should not cause any problems other than having to reset the windows. I've had no problems with mine since I charged it up when i posted this...

Fully charged over night on Monday and seems to be holding full charge so far. fingers crossed...

I measured the amp draw with the car unlocked and it's reading .13amps I take it this is the clock and radio settings using this. I mostly only use the car twice a week unless the weather is really bad and this is for round trips of over 20 miles. The battery is 70 amp hour so shouldn't go flat in 4 days. I think I may have left the side lights on and didn't notice the warning buzzer which is working ok...

Nothing seems to last as long anymore. Can't see new cars lasting as long as my Lexus at 18 years old...

Only 2 years old and was a good make

Does anyone know of any common problems that cause the battery to go flat other than I have left something on... Car not been used for a few days and battery flat only reading 8volts...

I had an early 90's 2.9 Granada that hit a bad pothole one morning going to work and had to be towed into work to find the inertia switch had triggered...

I do. I trained as a mechanic in the 70's

As you say modern electronics are probly more sophisticated than the 90's cars. I looked in the handbook and can't find anything about this. I was more used to working on cars with points and plugs and carbs. Electronics is over my head.
