Did you have the battery disconnected for storage?   If so, it's in the "re-learn" process. Drive it for a few days with lots of starts - run a number of miles - shut off, cycles.  Then see how it runs for you.

Ok so I got the pcm today. Put it in and everything is running ok.. now I'm getting a code of p0171 running lean I think. Now the engine is idling like Ime having a valve issue. Is it putting like that because of the engine code. Or is it that the valves might be sticking. The car was sitting for 8 months to a year

 

Scotty kilmer has a video that is for that same code, and might be relevant to you. That code means too much air or not enough fuel. on my '10 the intake manifold was plastic. You can do his trick with the carb cleaner (or starting fluid) 

 

When i got that lean code it was also able to register that a cylinder was misfiring. I replaced that cylinder's injector (after getting confused about chevrolet cylinder numbering vs ford) and it worked fine after.

 

Edit: grammar

Thanks for you responce.. im not getting a misfire code just bank 1 being to lean... i replaced the gaskets in the intake manifold. I also sprayed every hose with carb cleaner and also the intake and all over anywhere there could be a leak, nothing. Im trying to replace the bank one oxygen sensor as we speak and see if that helps.. Also im doing a furl pressure reading tommorrow to see if there is a glogged injector or something.

Any luck?

Nothing yet.. its hard to start when its cold out andd when its been sitting. But once started it will start back up qith no promblem.. havwnt figured out the po171 code, no money. Also im hearing clanking knoning noise coming from bank 1... it only happens when the car is first started cold. Goes away within 15-30 seconds.

So it had a vacuum leak coming from the EGR valve it was stuck open. I Replace the EGR valve and no more leaks. Car is still misfiring and I'm getting some code of p0430. Something to do with bank2 catalytic converter isn't performing properly. I don't want to replace the 400$ cat and the misfire still be there.. What should I do

[Tlove1]

I swear I fix one code and than another pops up lol

[4N1M4L]

I'd probably just take it in. Cat codes could either be your cat being melted from misfired gas, or an o2 sensor, but if your just throwing parts at it then 400 might be cheap.

[Tlove1]

Well I did take it in they b said the 02 sensor is bad and also the cat. But my thing is I don't want to replace the cat if I didn't fix the misfire.. Is it safe to drive with a bad cat/02 senaor

No, it isn't but see my reply in your other post.  Please don't create duplicate threads.
