I have a 2003 nissan altima. this car is burning oil like crazy. there's no smoke or anything of that sort, but i have to keep an eye out and put oil in my car to keep it running at least every 4-5 days or so. gas is high and oil is getting higher; i have to keep at least 2-3 quarts in my trunk. the check engine light has been on for sometime now. while driving on the interstate if i go over 70mph the check engine light starts blinking. when i take my foot off the accelerator the check engine light stops blinking, but continues to stay on. however, i just had my spark plugs changed and now the car won't start. please i need some help asap.... i don't have money to purchase a new one at this time, but wish someone can tell me what is going on. the dealer is no help whatsoever. they get you in there and tell you that this, this, and this is the problem. it seems that nothing is under warranty with nissan, and i don't own the car as of yet i'm still making monthly payments. i think that nissan needs to go over the engine, electronic, and etc. because canton, mississippi is the home of nissan and you have some big problems on your hands!!! *tr
