Engine Light On

[z280]

I currently have my engine light on. It started about 3 week ago. Only thing that was done recently was replacing the windshield due to a small crack that turned into a large one. A few days after that, that's when the engine light came on. I replaced the K&N drop in air filter that I had installed originally with an OEM air filter - thinking that was the  cause. A day after that, the light went out. That only lasted a day before the engine light came back on.
What's strange is that I took the car to get it cleaned at the car wash, and when it came out  the light was off. That to only lasted a day before it came back on.
I check the gas cap every time I refuel to make sure it is properly closed. That would cause the light to go on if it's not sealed correctly. Reading the manual it indicates that the grade of gasoline could cause it too. I've been using 93 or 91 octane since it performs better than 87. The manual indicates 87 or better.
I took her in to one Saturn dealer and they said it was the air sensor.
Any ideas or thoughts that could cause this.. Appreciate your response.

if they said it was the MAF did they bother to check it or correct the issue?

from my experience the MAF is very sensitive in the car. But if they think that's the problem, it's their responsibility to make it right.

Your correct Mr. Clarkson. The dealer that I took the car was near my job, and they have no records of my warranty. Therefore I'm taking it to where I originally purchase it. My records on are file, so there shouldn't be any out of pocket expense for parts.

I'm not sure if this will work on our Saturn's, but across the pond, there is a method for displaying the error codes.

-Quote-

- Take a seat in your car...
- Press the brakepedal and the accelerator-pedal fully at the same time
- Turn the ignitionkey till the lights in your dash come on but don't start the car!

In the display where normally your mileage is shown, you'll see "ECN" (error code number) and below it the faultcodes that have been stored. They appear one after another. At the end, your mileage will be shown again.

The first 4 digits indicate the fault, the last 2 digits contain a value.

For example: ECN 161450: problem with communication between immobiliser and key-transponder.

They're all built in the same factory, so I can't see why that wouldn't work. One thing I have noticed though is, my 2005 Astra will display ECN 000000 if I do not have any error codes, but I've recently been looking at buying a 2006 Astra which won't display anything if there are no error codes  Not sure what your 2008/9 ones will do if they have no codes.

Just to update you on this thread. I had the MAF replaced. That took over 3 weeks for the part to arrive - guess the part is from across the pond. It was working fine then it started again, engine light goes on or off. Took it back, and now they have to order another different part. Not sure what part it is, but it's not the MAF. So far it's been 2 weeks and the part hasn't arrived. Perhaps I drive her to hard. I'm usually doing 80 - 90 mph on the interstate.
