Sounds like the ECM/PCM is finding an intermittent fault,There are a few part stores that will run a scan for free.If your car is running good,it doesn't sound like anything major.some cars do this after so may miles to let you know its time for a check-up.They can write down the codes for you and erase the old codes.then when you drive it again the light may or may not stay off.If it comes back on have it scanned again.they can tell you which part is acting up. Hope this helps and good luck

Whats the main with the daytime running lights

The daytime running lights are on for safety. The engine light needs to have the error code extracted from the computer and then investigate that indication. The error code is not necessarily the cause or issue, but rather a clue.

On initial startup unit runs good. After unit starts to warm up with defroster running engine service soon light comes on and stays on? Any ideas?

That's just a service reminder light. Usually indicating it's due for a particular service at a specified mileage. Any good shop or parts store can reset that for you.

Check engine light on but car runs good

The check engine light comes ON when the cars computer (the ECU) notices any kind of electrical problem in car. In this case I suggest you to get your car scanned at autozone service center. It's absolutely free. In scanning the error codes will be retrieved.As per the error code you can check which part is faulty and replace that particular part. This will solve the problem.---------- This will help. Thanks. Helpmech.

While running suddenly the service engine light comes on, my gages start acting funny and the car either stalls or runs very rough, when the light goes out the car runs fine again

You will need to take your car to an Auto Store (i.e. Auto Zone, O'Reilly's...) that have a FREE use of their diagnostic equipment to see what engine Error Code was set. From that, you can (kind of) tell what component(s) has failed or is failing and causing the service engine light to come on. Could be one of a dozen things like bad oxygen sensor, mass air flow sensor, EGR valve and on and on. Find the code and that should head you in the right direction.
Good Luck

I've changed the oil, checkd tranny fluid.. but the service vehicle light keeps coming on..

This light comes on when a sensor tells the computer that there is a problem with the engine. First thing, disconnect the battery for 5 minutes or so. This will reset the computer, and dump the error codes. Run the car. If the light comes back, have it scanned at a parts store, and they can give you the error code with a probable way to fix it.

Service engine soon light came on, what would cause it to come on

a service engine soon(SES) light, malfunction indicator light(MIL) or check engine light coming on means you have one or more error codes in the powertrain control module(PCM). these will need to be scanned or read with an OBDII code reader to determine what the problem is. most likely an emissions sensor has failed. but this could be any of a dozen or more sensors or meters causing the light to come on, and once you have the error code you need to pinpoint the failed part. hope this helps, good luck!

Turns over but wont start. 1997 chevy 2500 4x4

Check to make sure that the grounds are good on the engine...the scanner error could be that...and does the service engine light come on when you turn the key to run position? If not, I would take a close look at the PCM.

Error Code

p0605 reffers to a pcm read only memory (rom) error...Not likey a good thing..I would take it back to where it was serviced. At times unplugging the scanner while the vehicle is running and scanne in the middle of a test can cause that light to come back with that code. For sure return to service facility and get them to fix it.....
