Use a regular valve cover gasket. Why would you want to substitute an OEM rubber gasket with FIPG? You can try it if you want but the seating surface on that valve cover gasket isn't like the one on your oil/tranny pan.

How were you even able to check the "gap" on a +4 plug?

Only a handful of cars are E85 compatible, and Lexus isn't one of them.

What kind of budget are you working with?

You should look into buying DLS or CDT components. Those companies make decent, good for the money, SQ component speakers. BTW, I have a pair of Zapco amplifiers that I'm selling. Let me know if you are interested.

That wasn't the best method to test an alternator but yeah, the alternator is still good.

I'm using Ignition Solution Plasma Coils right now, so yeah...it's better than the stock system. The +4 plugs probably work better in Euro cars because of the combustion chamber design and head flow. No, I don't think it has much to do with the type of ignition system because old school BMW's use the +4 plugs and the ignition system in those cars is similar to what Honda and Toyota used. Bosch +4 plugs were OEM on BMW's but they recently switched over to NGK +4 plugs, only because the NGK's are 100k mile plugs. The reason a lot of you guys hate Bosch plugs is because you guys are using the +4 plugs. Bottom line is that the +4 plugs will not work well unless properly matched to your application.

Have you checked to make sure that the engine isn't flooded?

My car runs like crap on regular plugs. Whatever plug is helping me lay down 518/rwhp is the best for me and that happens to be +4 plugs. ;)

Take it to a shop to check for leaks and make sure that the A/C compressor is actually "kicking on."

Isn't the car still under warranty?

If you plug the MAF sensor in and the engine stalls, wouldn't that give you enough reason to test the MAF sensor?

How many miles are on the car? Has the fuel filter been replaced?

What is the name of the pulley? What's wrong with it?

How did you find a four year old post?

Are you sure that it isn't not oil?

I dunno? They still work... http://us.lexusownersclub.com/forums/index...er=all&st=0

I know that Bosch plugs don't work well in Jap cars. Look at my post above dude. But Bosch plugs aren't crappy either because they work great in Euro cars. If you must use a +4 plug for a Jap car, use NGK +4's.

LOL. If a racoon did that kind damage to my bumper, I would of brought him home...for dinner. ;)

Just paint it or have a shop powder coat it for you.

Umm, have you considered testing the MAF sensor?
