Got my codes read.. the autozone rep was surprised to see soo many codes... oh no

[bskicrash1]

Well, to make a long story short... When i start the car when the engine is cold, I have to hold the gas pedal down because the car has an irradic idle at first and will stall out. Once started, the pedal only has to be held down for about 10 seconds until the engine starts running smoothly and then the car runs perfectly fine.

The other day after this happened, the service engine soon light started flashing at me..... and then stayed on constantly... so i proceeded to autozone to get the codes read.... they are as follows:

p0300 Random/Multiple cylinder misfire detected

p1651
QDM B
Quick Fault

P1650
QDM B
Fault

P1599
Engine Stall or Near Stall Detected

P0326
Knock Sensor 1
CKT Range/Perf
Bank 1 or 1 sensor

P0605
PCM
Read Only Memory
(ROM) Error


All of this because of a crazy idle at first.... The autozone worker reset the computer and since then the Service Engine Soon light has not come on...


The workers at Autozone said it sounds like it may be caused by an air flow sensor or a throttle sensor... something that will affect the mixture when i first start the car

Any Ideas? Thank you for your help

I'm sorry but you need to get to a saturn dealer and have them scan the engine for codes.
The guys at Autozone don't have the know how and with the codes they gave you you need to have the dealer diagnosis the car.
Then you'll know for sure...

Get that fixed and see if the others clear up. If the PCM is toast, I wouldn't trust anything else coming out of it.
