New (used SVX) slight probs

Hey guys,
I just got my svx 92 LS-L pearl. I love it drives great but I have some concerns.
The power light flashes when I start the car then goes off. But when I hit the gas it doesnt come on-- at all. Also the check engine light came on so I shut the car off and it went off. Happened twice----guess I have to bring it in to the dealer.
But besides that im very happy with the car.
Now I just need to sell my mustang !!!!
