hello again, so speedo quit working? and it is not running good? did this happen at same time? also, I still need to know what sensor you were told that is discontinued?

Customer: replied 1 year ago.
I was told the sensor on the transmission for the speedo was discontinued
Customer: replied 1 year ago.
I bought the car and replaced the motor with the same type ,the injector rail had to be replaced as couldn't find the original, i was told is now leaking and one of the injectors was sticking,there has always been a hesitation when accelerating. The check engine light came on intermittently so changed the plugs etc.. The light went off for a few mins and the car ran better but still has hesitation. The car was also back firing and well having mini explosions as it sounded like doesn't do it now until it warms up. I know a lot of problems there. It was suggested that that sensor might cause some of those problems as well as the coil pack too.

Good morning I'm Reggie. May I begin by asking you what part you have been told is disabled? If you are talking about the speed sensor uou have been told wrong, and I have never seen a faulty speed sensor cause your complaint. Have you had the car scaneed for codes? What is fuel pressure?
