Seafoamed this evening via brake booster. After pooping myself when it would not even hint at turning over after four or five key turns, finally it did and the wonderful MASSIVE cloud of smoke that was produced brought a warmth to my heart, and dirty looks from the neighbors - JOY!. Will let you know how it drives over the next few days. Again, thanks for the help everyone.

Toys...thanks for the tips. I suppose if I buy a Lexus ES repair guide (any particular recommended?) I could figure out how to locate, remove and then clean all these parts you've mentioned. You will turn me into an auto mechanic shortly. Much obliged.

Yes, 14mpg is about as good as the Hummer that someone in our condo building owns...surely I can at least beat that earth crusher! I'm going to Seafoam tonight thru brake booster, add to gas and oil and then drive for a few hundred miles before oil change. After that I will change the plugs too, maybe even sooner (how difficult is it to do this--I've done before on another car, but years ago) Thanks for the definitions, Toys, if things don't improve after these couple steps I'll look into them. Auto repair is not something I (obviously) know anything about, and $$ is tight...so want to try the cheaper steps first. This forum rocks, I love learning from you all. Thanks much again.

Going to Seafoam this weekend! The way you all talk about it I feel like I'm going to have a brand new car rather than the 94 ES I have currently afterwards! Or...perhaps closer to it than now. Trying to restore acceptable gas mileage (getting 14mpg city now) with this (also replaced O2 sensor 1)...how much success should I expect? It's going in the gas and oil as well as brake booster. No clue. I no there is no way that I would add it to my oil. I was reading on BITOG and even the chemist guys say no. Maybe they are wrong. I would use a safer fluid (solvant) in my oil; but that is me. If you do use it. I would run for about 15 minutes (as a flush, then drain). But the brake booster is the way to go. Wow, 14 city is pretty bad. Have to cleaned the TB or IVAC at all? PCV Forgive my ignorance ...I am learning as I go on this board. What do TB (timing belt?-if so, no, not due for another year or so) and IVAC stand for? Even without knowing I can say no, they've not been cleaned. All I've done is the new sensor, checked tire pressure, etc... I am planning to replace the plugs in the next few weeks (how tough a job is that for a novice?) as well as oil change in same time period. PLEASE TELL me this won't screw up my new O2 sensor, however...?

Live in Chicago, not too many hills but hot, a/c, and lots of stops and starts. I drive pretty easy, especially once I realized I was sucked gas down. I calculated by # miles driven to how much gas I consumed, 94 Lexi doesn't have the cool little computer unfortunately. Weird, but I'm trying a few things (posted on them already) to see if I can knock it up. Otherwise it's back to my Civic according to the wife! Nooooooooooo!

Read enough about Seafoam, going to try it. I am fairly certain which one it is, but can anyone provide a link to a pic of the brake booster vacuum hose that is to be put into the 1/3 can of Seafoam? I have '94 ES300. So: Car running, disconnect hose, insert into 1/3 volume of the seafoam, allow car to stall (if it does not, turn off immediately), reattach vacuum hose, wait at least 5-20 minutes, start up and enjoy smoke. Do I have it? Thanks all, I've learned alot from you guys.

There's no carb on your engine.......it's fuel injected. :) Ah...my complete and total ignorance of engines and all things car-maintenance related has been exposed! I presume the Seafoam treatment is still a good idea? Why on earth would this thing get such good mileage hwy and such lousy city? My wife is going to make me drive our Civic if I don't solve this problem!

New Member with 1994 ES300, 125K miles, bought from mom a couple months ago. This forum is excellent, so much knowledge. Here's my question, I'm getting about 14mpg city and I drive nice and smooth and slow all the time. Took recent trip on hwy and got about 27mpg...that's not bad. bank 1 sensor 1 O2 replaced a couple weeks ago, engine light now off, but it had been ON with the bad O2 sensor for at least one YEAR before that (according to Mom!) Power is okay, but not great, otherwise engine runs very smooth, no problems. Based on reading through the threads here I plan to: Change spark plugs (must wires be changed too, or can I wait on that?) Check air pressure (Air and Fuel filters replaced about 2K miles ago) Perhaps try the Seafoam I keep reading about here. How do I know if car is in "limp mode"? Final question: can someone direct me to online manual-type thing with pics on how to change the spark plugs and how to locate carb, etc...so I can use the Seafoam. THANK YOU!! --mrb
