I have a 2004 Cadillac CTS shifting a little hard check engine light is on due to a dirty fuel injector just bought the car it's nice but can anyone help a little?


check engine light is on due to a dirty fuel injector ??? What code ? Shifting hard could be caused by a lot of thing's having it hooked up to a professional type scan tool to check certain sensor inputs to the PCM/TCM would be the first step in a diagnostic trouble shooting process. Cadillac's are a different breed of vehicle then your normal vehicle . If you don't have or know about a professional type scan tool . not the one they use at auto zone .Your best bet , take it to a Cadillac dealer. I have over thirty years experience at a Cadillac dealer . You don't have the knowledge or tools to test it .

What does code po700 mean on a cadillac cts 2006


From:


P0700 is an informational code only. It doesn't point to a direct fault in the engine, only a general fault in the transmission. More diagnosis is necessary to identify what the transmission fault is. This requires a scan tool that will communicate with the transmission module.
More often then not, the cause of this code is that there is a transmission problem of some kind. The TCM detected the problem and set a code. P0700 means that a fault code is stored in the TCM. However this doesn't rule out the possibility of a failed PCM or TCM (unlikely).
For a P0700 the only real solution is to acquire a scan tool that will communicate with the transmission control module. Extracting this code from the TCM will be the first step in repairing the fault in the transmission.

2003 Cadillac CTS won't start after disconnecting battery


Don't do that again! You will need to re-boot the on board computer system by entering a code. Call your nearest Cadillac dealer.

My engine light is on told it was oxgen sensors is that right


If they connected a scan tool to it and retrieved the error code from the computer and thats what it told them more than likely it is. Depending on what code it threw it could be something causing it to throw O2 code.

CTS CODE PO420


most of the time its the sensor that cause this,id try replacing the sensor on it,that usually fixes that code,but you have to get the code cleared off with a scanner ,and then re-scan it to make sure it doesn't come up again,good luck with it.
