"had a couple of misfire codes. may need coils later on. will need third 02 sensor"
I have had my car in for repairs for over a month now, I pick it up and another light comes on, usually the service engine light and the VSC light. It does affect my mpg. I have now spent over $1700 and have replaced the front oxygen sensor, downstream oxygen sensor and both knock sensors.... What the heck? If the lights come back on again, then what??
I think the stabilizer rod, bushing is shot.
Losing power hard acceleration
My VSC and Check Engine lights have come back on, which has happened a lot in the 10 years I've owned the vehicle, usually after getting gas, etc. I'm now getting the Check Engine light blinking if I go anywhere near 60/3rd gear, and exhaust smells at times, with the acceleration seeming to slowing down, or reluctance to accelerate. I've had my wiring replaced a couple times due to the car not wanting to turn over or, if turned over, not accelerating/jerking. I've also gotten a new alternator/battery.
i have problem with abs beacuse fuze was blone i replace that since than car is not stoping way is sappose to be is skiddind than stop after i check tire brake senser is looking fine what else can be a problem
Fuses are all good but no power to panel fuse or brake light fuse directly above it! wires seem to be fine. After about 20 miles starts to idol ruff and will not exhilarate to highway speeds!
how much to replace rear main oil seal
it shifts ok for a few miles
it is a squeaky noise and after the air gets sucked in it stops
lock door function will not work electronically and
lock button will only work manually
can exit the car only if I click the unlock on the key or the unlock button manually

further usually now if I open the door and click the lock function and close the door, the doors will lock electronically , but after I walk a few feet half the time the alarm will go off
if I then click the unlock button on the key and then the lock button the alarm will stop , relock and stay locked

both a Toyota and Lexus mechanic have examined it and are stymied
the Lexus mechanic guessed that the driver door mechanism must be replaced, but 2 tests he asked me didn't work
1. when alarm goes off look to see if red door button switches back and forth and 2.listen for a clicking/unclicking sound comes from the driver's door

neither ever happened

I have a lexus 2000 rx 300 that has trouble code 1354 I have a check engine light on that blinks on and off from time to time. the Trac light also comes on after the car is warmed up The car had been running fine. Now, it smells like gasoline, especially noticable when I start it. It runs a little rough at idle. It also has developed a problem with shifting. What I would call "third to fourth gear"; what I notice is that as it speeds past 40 MPH and then to 50 MPH, it should shift, but it doesn't. It acts like it's in L2, but it's in D and the overdrive is ON. If I take the OD OFF, it doesn't change anything. any ideas what the problem can be
when am driving and want to apply brake i hear a brake warning and when i continue accelerating it stops.continue in that process as i try to apply again.
Plus the car is riding rough when cold. I did change the gas cap but now it is on so tight that I have to use plyers to remove
