Hi again guys: So I have an update on the ownership of my new rig: I have my first CEL and It happened on a mountain highway up to Whistler this weekend. I think that the problem is associtated with a leak in the exhaust just before the cat that sits right under the front passenger seat. I ordered the gasket and will be fixing it shortly. I have Lexus pulling the CEL code tommorrow so I will see if this confirms my decision or not. I have proof that the Dealership actually had this CEL before but just had the comp. reset so if it is anything major I am going to press them to pay for it, I think that they probably will if this is the case. I put sylvania silverstar headlights in it today to brighten up the headlights a little and I really like the diff. I also cleaned all the window tracks and lubed them with some silicon spray. I would like some thoughts from you all on cleaners added through the fuel..... I thought perhaps I should put some injector cleaner or something through the system just in case, will this harm the injectors at all? I was also looking for some fuel additive that would clean the catylitic converters, 1 does this exist 2 has anyone tried it? BCLX450.
