mpk92sc300

Hello, My 92 SC300 groans from the rear, when I am slowing to a stop, sometimes it makes a high pitched sound also from the back. Any ideas on what that means and/or how much it will cost to fix it? Thank You MK

I have a 92 sc300 170k miles. Its acting up, low gas mileage usually get 250 miles to the tank of premium, used to get around 325 miles from a tank of premium. Car smells funny, like disel fuel, and it vibrates at stop, and after I driven about 30 miles then the car sputters and acts as if it might stall. I took it to a mechanic who rebuilt the ignition system for $500. I picked up the car and it acted just the same as before. So I took it back, they are offering full credit for the ignition repair, but say real problem is the head gasket. Citing coolant isn't flowing through radiator, and low compression. Also, something about milky oil, and blowby. They claim the real problem before was the technician but now have called in a master diagnostician. Obliviously this is expensive, $3k repair. Do any of you have an opinion about the diagnosics, or if you think its not worth fixing such an old car?

I have a 1992 sc300 with 197k miles. Ive had trouble this last week with over drive light flashing on and off and automatic transmission feels like its slipping, wheels not engage? Anyway I took it to be fixed, they think it's the THROTTLE Sensor and estimate repairs at $485-- they want to wait another day to see if they can get the transmission code to read out the error code. By the way my local AutoZone says they only have the engine code readers and they don't have one for anything older than 1996 for Lexis.
