any thoughts!?!?!?!
thanks in advance

 

what engine?

 

and the service engine soon light is coming on too . . .

 

305 tpi

 

Well, let's get right on scanning that ECM for error codes, so we can get your engine running.

 

ok-whats the ECM? and how do you check it?

another thing that I noticed this morning-its staying at about 1500rpm, and the 2 fans are coming on .. . maybe that helps

anyone else has any ideas, cause i would rather fix it myself then take it to the dealer or anything

 

First, you'll need to acquire a GM OBD I ECM Diagnostic Trouble Code Retrieval Tool (commonly known as a paper clip to TGO members).

With the engine and ignition turned off, locate the ALDL connector under the dash, just to the right of the steering wheel in the driver's foot well area on Firebirds, and on the left on Camaros. There should be a small rectangular cover over the access hole in the lower dash trim.



Insert a tool as described above (paper clip) into the 'A' and 'B' terminals on the ALDL connector:



WITHOUT STARTING the engine, turn the ignition to the "RUN" position. Watch the Malfunction Indicator Lamp (MIL) - it will begin to flash. This is also commonly called the "Service Engine Soon" or "SES" lamp. The first code will flash three times, and will usually be a code '12'. This is encoded by one flash of the lamp, a brief pause, then two successive flashes of the lamp. Each code will repeat three times, so you should see a "Code 12" flash three times. Any other error codes will follow in numerical order, and each code should flash three times. After all codes have been displayed three times, the "Code 12" will again flash three times, then all other codes will follow as described earlier. This cycle will continue until the jumper is removed or the ignition is turned off.

After you have made a note of all error codes, turn off the ignition and remove the jumper immediately. If you forget to remove the jumper and attempt to start the engine with it in place, you could damage the ECM. For this reason you should remove it immediately.

Once you have a note of all error codes, check this file for the decoding:

GM Error Codes.pdf.

You'll need Adobe Acrobat Reader to open/print the file.

 

hey, thanks a lot vader-looks to technical for me! im gonna have my mechanic look at it for me and see if he can fix it, otherwise i'm gonna take it somewhere and have a diagnostic test done-
