The engine is not performing well, especially at idle speed. The engine rpm is bouncing and there is no vacuum leakage.
The transmission is not shifting properly. After scanning the vehicle there is no code found on the memory but there are some wires that have been interchange on some of the system because most of the connectors has gotten broken.
Please could I have the complete wire diagram for the transmission and Engine. Thank you.

Hi,

I need to know if it is a 1.8L or a 2.4L.

Thanks,

Hi,

If you look below, the first 8 pictures are the powertrain management schematics. The last 4 pics are of the transmission circuit.

As far as the schematics are concerned, I had to cut each page in half to make them readable. I did overlap them so you can follow from one to the next.

I hope this helps.

Take care,

Joe
