Okay, here's my current problem. I cleaned my throttle body the other day and got check engine light afterwords. I reset the ECU and no more light, so i guess thats good.

Anyway, i have what i think is a transmission problem now. I will be driving along and it seems like the car will downshift. As im driving i feel the throttle slow then it speeds up again. When it picks up the car kind of jerks like a bad shift, sometimes it is really hard.

Could this have anything to do with me cleaning the throttle body the other day. I remember seeing something about a throttle position sensor, could i have screwed something up.

Thanks.

P.S. Its an auto with about 160k on it. just had transmission flush about a month ago at dealership.

 

You should have pulled the code when the CEL came on. That would have probably pointed you in the right direction. You may not have a tranny problem, but rather an engine issue. Make sure you didn't disconnect the drop resistor when you took the air cleaner top off.

 

Thanks for the reply. But where is the drop resistor.

Also any other suggestions?

 

i think i have the same problem, minus the TB cleaning and the sudden jerks, but defininatly the RPM drops... it just started happening on its own.
