2003 Saturn Vue Troubles
 

I have a 2003 Saturn Vue with about 62,000 miles on it, and have been having some problems

My service engine light came on last month and wouldnt go off for about 3 weeks, I thought it was the gas cap being loose after the first week (i have had that happen many times and i would tighten it and it would go off in about 3 days) this time it didnt go off after getting gas 2 more times and making sure it was clicking to tighten the cap.

After 3 weeks it went off and then stayed off for another week and 2 weeks ago its come back on. i have a little hand held reader which i checkedf last time it came on and this time and I get 'no code'

I dont know if this has anything to do with the other physical problems im experiencing with the car. if im going over 30 mph and i start to come to a stop my steering wheel will shake. Im having problems getting enough power? to get up hills.

I was noticing a chirping like noise whenever i would excellerate from a stop and that has stopped and only happens when i have the air conditioner on.

I did replace a serpentine belt? 3 months ago.

I had my oil changed 1,000 miles ago and i watched the guy reset my light but now my change oil light will come on when i start and stay on for about 5 minutes then go off. I dont know what thats about.

Last thing. I had an automatic starter installed and he did it by hooking things up under a panel thats under my steerling wheel he never did anything under the hood, either way now when I go to lock my doors with the new remote it doesnt beep as if the alarm has been set and im wondering if that means he disarmed it? and how can i get the beep back.

Sorry this was so long :/

take to nearest saturn dealership and get it fixed

Don't know who did the remote start installation, but from what you describe, it sounds like his efforts have not meshed very well with your Saturn. I concur fully with DERF -- take it to your Saturn dealership, and be ready for some 'shop time charges' ...
