07 L5 3.7 engine installed in a 09 hummer h3 3.7 09
I put the 07 3.7 engine in my 09 h3, now it don't start right, and runs rough down the Hyway. I know that the actuator is different between the 07, and the 09 engine. I rebuilt the 07 engine, then installed it in my 09 h3. I got a new position actuator sensor, and wired the 07 plug on my 09. Didn't make any difference. Will have get the computer reprogramEd? Thank you for any help!

07s and 09s use different PCMs, your 09 PCM is not programmed to properly run the 07. I have heard many will run, but not like they are supposed to. You need some programming.

Reprograming
any suggestions where to get the pcm reprogram? When I rebuilt the 07 engine, the only difference was exhaust acuator, I didn't find any difference on the block, I should rebuilt 09 head, and put it on the block. I don't know about the cams..
