1st it was the o2 sensor's had those replaced, now the engine light is on again and it's throwing codes 13 (RPM Circuit #2) and 24 (Intake Air Temperature sensor). When u start the car if just sputter's and shut's off unless u give it some gas but once u let off of the gas it shut's off. any suggestions??? thx

check engine light and trac light came on, codes was 21-27 and 28-29, front and rear 02 sensors, i had them replaced at the shop with Denso oe identical fit 02 sensors they cleared the codes and one day later the check engine is back on showing the same codes, i unhooked the battery for 10mins, hooked it back up and guess what? the check engine light is back on showing the same codes again!!! what should i do next??? thx for your help

I have a 92sc400 with 123,000 miles on it was driving on the hiway i let off the gas and the car stalled, it will start but won't idle unless u hold your foot and the gas, cel and trac light came on i tried to check codes TE1 and E1 (diagnostic) and the engine light just flashed repeatedly non-stop, am i doing something wrong? i want to check codes before i get it towed to the shop. thx

PURCHASE! PURCHASE! PURCHASE!

9500 for SC400 (can't believe i talked him down that much, had money in my pocket!)

the clinching deal... 2 things...

1) the timing belt was done at 54,000 miles by the mercedes dealership that he bought the car from... then he had it done again when he took it in for service at lexus dealership right after purchase less than 600miles later... the regular maintenance done by that dealership was key in my purchase (i spoke to the dealership)

2) he had also 4 new yokohama's on the car.... i checked the spare ,it also was a yokohama and new... he had repalaced it too!!! I asked him and he just thought that was how things were done.

total miles under 60,000 ( under 100,000kms)

good deal! enjoy your ride

4K. I have replaced the master control switch and fixed 2 broken wires. Now I am looking for a drivers side window regulator and motor to get it fixed.

Japanese parts is located at the End of Lamb Blvd has all kinds of parts for Lexus and Toyota. You can get all the parts you need from there. Good luck

Thanks. I will have to check them out.

nice ride you'll enjoy it! welcome to the club

I have allowed the car to run for over 20 mins, but continue to get surging RPM. Actually when the car is cold it idles higher than normal about 1800 RPM then once the car warms up it tries to idle down then begins to surge at 1100-1700 RPM. It would really be nice to actually replace the correct part since parts for this vehicle can be be very expensive.

Thanks

wow man this is perfect timing my car is doing the same thing once it's warmed up idle surge from 1000-2000 where can i get a repair manual?? thx

just wait until you can buy them. The error code will remain there.

you can get them cheaper than that check out sparkplugs.com it's a good site with 02 sensors, wires, plugs, filters.

there should be a couple of screws you can reach behind the MudGuard. The light connector is also there.

ok thx

how do you change the orange (marker) light that's on the front bumper (drivers side) does the lens pop out? or what's the trick :D

If you go to AutoZone (there may be other auto parts stores that do the same). They can run a diagnosis for your check engine light. Once that is done you have a good staring point.

Good luck,

I had that happen to me I have a 92 SC400 had it check out and was told that i needed to replace the 2 front 02 sensors, don't no about the radiator light, i have 120,000 miles on mine, let us no what you find out. good luck

I always tell people to buy an OBDII CAN reader..Well worth the $$$$.Napa reads codes for free but does NOT test for OBD readiness.

ok thx i'll have to buy one of those
