i have a 95 es 3000 that i have been working on and have been having a few issues with. At first the car wouldnt start and would not let me get any codes off the ECU so i figured the ECU went out so i got a used one and replaced it. The car started right up and ran smooth. I drove about 30 miles and the Cel came back on three codes popped up. it was p0500 and p0135 and p0720 and the car would not shift into fourth gear. So i replaced the OS sensor because it was the original and figured that it was bad and sometimes it can cause issues with the car other than the emissions and rest the codes. So i drove the car again and it would still not shift into fourth but the rest of the gears ran smooth and the Cel light didnt come back on. So today i drove the car and every time i put it into drive it would stall out in first but if you put it in L gear and then in 2nd and then to D it would drive but it felt like it would slip in 3rd gear a lil bit but it now goes into forth gear. And i now have the Cel light P1705. has anybody had the same issues and if so does anybody know what they did to fix the issues.
