I need some help!

[lunatik]

Hey Guys,
     hopefully some of you guys can help me out!  Here's the deal, I hadn't driven my car for about a week now.  Tonight I decided to take it out for a spin. When i turned the car on, (I had it in neutral with the E-brake on).  It seem to be idling low, and it kept shaking for about 5 minutes.  it was too dark out, to be able to see anything under the hood, so i decided to take it for a spin.  Normally the car accelarates pretty good, but tonight it would accelarate, and then lag for a second, then accelarate, only lag again.  It felt like a #### rollercoaster, my gf said she was getting sea-sick from it, lol!  This mainly happened through the first 2 gears.  i know one thing the car is not running like normal.  The check engine light has also come on.  I'm not too familiar with the 240 overall.  I've had it for a few months, but i haven't driven it too much.  Does anybody have a clue about what it may be?  If so i would appreciate any help, Thanx  Lou
