I have noticed this problem for a while now. Today, when I started up my car, I noticed the power from the engine drops like it is about to stall but then it quickly powers up again.

What will happen if my engine shut downbefore I take it for a tune up?

 

It's likely missing ... causing the shakes ... could be plugs/wires/cap ...

 

We got into that problem several times lately. I'm still dealing with it myself. It on here, some of the answers anyway.

 

Have your IAC (Idle Air Control) cleaned

Take of your Intake Hose from your Intake and spray some foaming C/Fuel Injection Cleaner in there till it fills up then go turn your car on slowly leaving the key in the different possisions for about 2 secs and keep on doing this about 4-5 times....

there is a little hole under neath the flap that opens all the way more than likely it's dirty....... It doesn't sound like you missing don't worry about your plugs or wires yet...... ok!
