I have a 1995 3rz with 108,000 miles.
Today the engine started shaking as if I was lugging it and its running very poorly. I shifted into 2nd normally and it felt like I went into 5th. It idles rough like that now. The check engine light came on and the truck has a bad smell while running now. I disconnected the battery for 15 minutes and the light went out but it still runs poor. What could the issue be? Could it be a sensor like the MAF that has gone bad? Would the computer try to adjust the air fuel mixture and be flooding itself?
Last week the transmission started popping out of 3rd gear while driving 30 mph several times a day. It also feels like the shifter isn't traveling into 4th gear as far as it should. The synchro bearings are worn out. The dealership doesn't rebuild transmissions. They want $3400 to replace the transmission. A local shop will rebuild it for $2000.
Any help or advise would be appreciated. Thanks in advance.
