I can almost guarantee the issue with these ECUS stems from faulty electrolytic capacitors much like the gauge clusters that have that flickering problem.

It's water in the spark plug holes... Around the engine there is a plastic covering where it says "V8 4 CAM 32" that covers the spark plug holes. While it does have a rubber gasket on the edges, two things are possible, 1. It wasn't installed properly so the gasket doesn't seal tight, letting water in. 2. The design is crap and no matter how it's installed, water will migrate into the spark plug holes, causing the plugs to short to ground, therefore causing a misfire. I felt compelled to chime in because this was an issue that stumped me for some time and I didn't figure out the problem until I stumbled upon a video on youtube discussing cleaning engine bays of Toyotas/Lexus vehicles and how water likes to get into the spark plug holes.

I have an ES350 and I've already taken off the bumper cover. I don't really need to remove the parking sensors but I want to know if it's possible to remove them in the event that I decide to get the bumper refinshed. I removed one of the sensors and I broke some plastic clips on the sensor and it just seems really difficult to remove these sensors without breaking anything. Has anybody had any luck removing the sensors? I have a sensor in the front bumper which is loose so I think I'll be tackling that issue some time in the future. Rear bumper cover wasn't all that difficult to remove so I'm wondering if removing the front bumper cover will be much worse or not.

Both links work surprisingly enough!

Yeah I know but the calculation for MPG and "real world" MPG, aka the MPG rating done strictly for consumers is very different. For CAFE purposes, GM's cars average 27MPG but according to the "new EPA MPG ratings", most car companies like GM average about 22MPG. The cash for clunkers program is a bit vague and it doesn't specify what method they use to calculate MPG, I mean for all we know they could calculate it by the MPG WE get which would be kind of silly.

I don't think you guys are aware but I don't believe this car will qualify under this program due to it getting such "high" mpg. Back when the car was introduced, Lexus made adjustments to the car in order for it to not get the gas guzzler tax levied onto it and coincidentally, it's only the cars that are considered gas guzzlers that qualify for this program.

I had a subscription to the TIS website for the past two days and it has expired, in that time I accured some what I think is valuable information that I'd like to share with all, I'm just waiting for the green light to do so.. I have the simple list and I have the ACTUAL PDF documents of the TSBs for 1990-2004 Lexus LS400 and LS430 Cars. I don't know if there is a FAQ with this already but I couldn't find it, so if you guys can, please fill me in.

Well, LLS...I replaced the fuel Injectors on my SC400 and it now runs like a stuck hog..I have almost 200,000 miles on it and I thought it ran great until I replaced the Injectors..I did notice 1 of the injectors was just a little wet on the bottom seal..so I just replaced them all and am I glad I did. I agree with you to a certain degree..if it isn't broke don't fix it..but in this case I was right!!! I also was told by a good mechanic friend of mine that changing the fuel injectors every 100,000 miles is a good idea anyway..they start leaking..their sprays get irratic and they can get clogged up over time..and fuel injector cleaner doesn't necessarily fix the problem either. They can just wear out too. I don't understand this post, it seems really contradictory, can you elabtorate? Yes I realize this is an old post but unfortunately this problem seeems to apply to me and I want more information.

does anybody know anything about wix? I was told that these were the closest to or are the same/better than OEM filters.

I'm generally and OEM type guy but I wanted to know if anyone has had a positive experience with replacing the LS400 '90-'94 fuel filter with an after market part. Stealerships in my area want to charge between $56-$65 for a fuel filter and I think that is really too high. Is there anything wrong with going with a fuel filter from the likes of fram or something?

Its good to see people actually using Ohm Meters to diagnose an issue before they spend thier Hard-earned money on useless replacements! :D I was hoping someone would post a list of diagnostic procedures that you can do cheaply and or w/o replacing parts. It seems like using a multimeter is enough to check most issues on a car.

I have a 94 LS with the same problem, looking for the solution.

I have a similar issue and did a similar thing, I am hoping there is a resolution to this issue.

Weak battery? I had issues with starting, replaced and fully charged the battery and that issue went away.

Has anyone ever replaced the fuel pump sock? Can I pick up one of these socks at autozone or something? (I have no idea what it looks like, and google images isn't any more helpful)
