Are the PCM or ECU the same in an automatic and a manual? just wondering cause i think my computer is shot. and there are some on ebay that i kind of want to try instead of taking it to the dealer.
its not whats under the hood, its how you use it
2200 soon to be turbo
depending on years they are the same. 96 is only compatible with 96. 97-99 i'm pretty sure are the same part numbers. And not sure about that. But say you take and have a 98 car now that is auto. If you were to get a 98 manual The computer are the same but the pragraming in them is different.
Also you have to use a computer from the same engine. 2.4 one won't work on a 2.2. Another thing is if you have a 3 speed auto you can use a 5 speed computer with it. But not the same for the 4 speed sense the computer shifts the 4 speed.
I see you have a 2000 2200 5 speed so you could use a 3 speed auto computer i believe. Or find a computer out of a 00-02 5 speed car.
So i could use one from a 97 - 99 that has the 2.2L auto and not the 2200? Im guessing that they are different. Because that's all there is at the wreckers near where i live, not one 5 speed, or newer 2200 but like 20 autos with the older 2.2L. And is there a way to tell if its a 3 speed or 4 speed and the year from the Vin #

Since your car is a 2000 it is a 2200. You want a ECU from a 2200 car. You could use a auto ECU in your manual car, but it will throw check engine light because it will not see a auto tranny. I would recommend getting a 5 speed ECU.

Let me clear something up...
If you want just a plug and play solution, definitely get an ECU from the same year group and transmission style, those groups are:
2.2L (Non-Eco) 95 (I think its the same as the 96-98 one)
2.2L (Non-Eco) 96-97
2200 (Non-Eco) 98-99
2200 (Non-Eco) 2000-2002
2.3L 1995
2.4L 1996 (3 Plug version)
2.4L 1997-1999
2.4L 2000-2002
2.2L (Eco) 2003-2005
If you are OK with getting the dealer to reflash your ecu, then you can get any of the following:
2.2L/2200 (Non-Eco) 96-99 From either a 2.2L or 2.4L of the same year group (96-99)
2200 (Non-Eco) 00-02 From either a 2.2 or 2.4L. Some rare 2.2's have Eco style ECU's and can use ECU's from Eco's (03-05 Only)
2.4L 96-99 From either a 2.2L or 2.4L (96-99), Some rare 2.4's from 96 have a 3 plug ECU and may only be used with ECU's from the same year/model
2.4L 00-02 From either a 2.2L or 2.4L (00-02) with the same style ECU (not the Eco style in some rare 2.2's).
If you use any of the above, the dealer must flash it. It also does not matter if its auto or manual, the dealer can flash it to whatever transmission style you have.

Buy stuff from CarCustoms Ebay! Won't be disappointed!
actually if you live in an obd2 emissions state, you will have to have the computer re-flashed with your vin, otherwise you will fail inspection because it thinks the station is running a different car than what is registered.
other than that, what shifted said is 100% right (as usual
)
well i got a pcm off ebay and put it in today, did the re-learn for the theft lock and the car runs again. the guy i bought it from it said that he was certified to program the pcm to my vin #. and it only cost me 71 bucks, pretty good deal in my mind. and the best part is that my remote for the door locks still works i didnt have to take it in to get it programmed. thanks for the help guys.

im curious as to why you thought your ECU was bad?

Ok, I think I am following you thus far. I have a '99 2.2 (2200) with 4 speed AT. So I can only use a '98 PCM or a '99 PCM with the same motor/tranny config. Did they make any 3 speed AT in 98-99? I am just trying to eliminate that issue if I order a used PCM online and the seller does not know this info? Also, I am assuming that the part # for the PCM would then be the same? My PCM, the sticker on it has fallen off so I do not know what the number was on it. Anyway to retreive this info if I need it rather than go to the dealer with my VIN? Thanks!

In my case, the dealer has done extensive troubleshooting and they cannot determine why the wife's '99 2200 will gives her hard start condition once the car has sat for 20-30 mins after reaching operating temperature. They are leaning towards bad PCM (which I am going to replace soon) OR in another thread it has been mentioned I may have a leaking injector but that is much more involved to troubleshoot and the dealer said its not common, unlike PCM replacements.

i figured my PCM was bad because i had an injector stuck open and i took a volt meter to the injector plug and the one that was stuck didn't pulse and all the rest did. i know it wasnt the injector itself because i pulled the fuel rail and switched the one that wasn't working with one that was and still the same problem. and i know it wasnt a shorted wire because i traced the injector wires back to the PCM and there was no faulty spots. so i figured it was the PCM. if you get an ebay PCM i suggest the seller spareecm, he will reflash it to your vin for free.

i just asked because alot of people dont take the steps that you did and just blame the ECU. glad you worked it out.
