Hi sorry for my english first of all
Here is my problem i got a cavalier 2.2l automatic and 2-3 months ago i got a check engine code i whent to the mechanic and he removed it told me it weas a sensor but told me that if it didnt come back no need to be changed . so I left it like that . Now it goes on and off but it still does the same thing : when the car is on idle it goes to 1000 rpm and the temp goes down to 40 and the tranny gives shoot evry time she changes gear.When the check engine code goes fo the car runs like a beauty . I went to the garage today and they told me they dont know what he as . ....,. Somebody help me im going crazy ... anyone can give me a hint ... any ideas
Thx alot
