Heres the short and skinny on my situation. Recently had my oil changed and tranny flushed and refilled.. Now my car is jerking when i accelerate and is slow to catch higher speeds. What do I do?

My check engine light has been on for a while and every time i take it in i always get the same response "did u fill your gas tank recently?" "It could just be your sensor." And then they reset the sensor so the light goes off only for it to come back on days later. Recently after the oil change and flush and fill tranny its started to become slow in response to rpm and lurches forward while driving causing my check engine light to flash until the lurching stops (usually at higher speeds). Before i took it to the oil, lube, and car wash place it didnt have this problem at all. What gives?

Trany flush? Not good. Is it the trany that is causing the jerking? So how does the motor run? at idle in park...

At idle its fine. It doesnt sputter or lurch or anything like that. Its when i press down on the gas that it starts to act up. Im told that if moisture gets into the spark plug areas it could do this?

Moister maybe so, you put a bottle of the Red Heat into the gas and run it. I am just hoping the trany flush didn't screw you. It is 99% of the time not recommended to do this as it blows any loose particles threw the trany and gets caught up in vital working parts. Like Tom said, check your fluid while warmed up, and run something with isyoprofel in it threw the gas, not methanol. You can only hope. May have to take it back and have them fix it.
