how to remove ignition switch on a 1999 lexus rx300
Hello, Drive Lexus RX 300 Production January 2003 With Gas Injection. Yesterday, when I was driving it, I was impressed that the dashboard turned off the sector where the automatic speeds were running, and the dipstick did not work, but the car was running normally. I stopped in one place after which she did not want to light. The battery was spinning, but it was not flashing. I tried to ignite it, the car ignited, but the speed lights and the temperature measuring arrow were not working on the dashboard.I went home and quenched it and tried again to burn it on gasoline. This time he lit up with difficulty, with the dashboard stop lighting completely. The car was working on gasoline just as if it was drowning, and I tried to make it out, and it went out, as the instrument panel was fine and worked normally, including now the speed and speed. I just lit it again, but the dash was all but extinguished, but the car was working.
There is a clicking sound ( like a relay clicking ) above the fuse box on the drivers side when the car hits 20 mph, this causes it to mis-fire, which seems like maybe a tranny issue, but when i step on the gas the clicking stops and it fires and goes just fine until i hit about 40 mph.. then same thing.. sometimes when it warms up it can do it at more then those two speeds.. I did replace 5 spark plugs and 5 coils, but could not get the middle back one out.. Also before this started happening, the check engine light came on and VSC and the codes were tranny solenoid.. which check tranny fluid and it was a bit low, put some in and it worked fine for two weeks.. then it started doing this.. took to tranny guy.. he was not sure.. said take it to Toyota... hmm.. hoping someone would be able to help before doing that... car is not worth what they want to even look at it.. i am sure..
It must have been a while (for the past year?). Passengers have said that the car smells musty. I only recently found it thinking that it was due to the carpets being shampooed and not fully dried. I felt the floorboard and it was wet. The mats themselves were not wet. However, the underside of it was wet. For the past few days, I've taken out the floor mats and let the underside of it dry. Isn't that odd? I felt the floorboard and it was dry the next day. As of this morning, there was still a smell so I put some baking soda for the odor. I vacuumed it and felt the floorboard and it was wet again. I don't understand this. No noises or leaks from my car that I am aware of. Please advise.
Thank you.

Bought this 1 owner w/130k 900 miles ago. No smoke in 78 degree weather. Check engine light on 3 days after purchase, dealer cleaned o2 sensor, apt. for new one. Then 1st notice a little blue smoke at cold startup cooler o.s. temp (45), sometimes a lot, not always. All cold starts. Used 3/4 of a quart in 7-800 miles.
Since then dealer free changed from oil partial syn to straight. Please no discussion about that experiment unless relevant.
2 engine starts since oil change, 1st little smoke, day 2 sustained cloud equal to previous worst. See what happens tomorrow.
Spoke to previous owner before I bought he told me he changed it with regular oil at home (but admitted that he let it go to 4000+ ,some bs about a little leak, cardboard on garage floor? No evidence of a leak ever seen).
Blank carfax for oil changes, assuming dealer serviced under factory warranty.
Very good once over at 86k.
Valve stem seals, sludge or what, weather temperature being the same on cold starts?
Thanks
No heating in winter. Heat stopped working - no heat at all. Lexus wants to charge $200 for diagnostics only.
It Stays in neutral. It has 202,000 miles. Recently had the transmission fluids drained and refilled. Currently waiting to hear back from the mechanic shop.

My 2001 Lexus RX300 idels rough & has 169k mi and just today we changed the plugs and coils on it. When we started it up it rans smooth and accelerated smooth like a new car again then took it for a lap around the subdivision and pulled into the driveway and the check engine came back on then it started flashing then it went solid again. Code b4 the plugs and coils said bank 1 misfire but the coil was still good but to be safe we replaced all 6 plugs and all 6 coils and havent pulled the codes yet because everywhere is closed on Sat. night and running short of ideas of what it could still be. I did notice a foul smell when idling when we returned to the driveway but then it went away. Please help Lexus mechanics we dont have money to be guesssing anymore:(
