Hi, my name is ***** ***** I will assist you.

When the engine light comes on and flashes it only means one thing...the engine has a misfire. That is what the shaking is all about, if you weren't sure already. It is really common for these engines to have faulty coil packs (coil on plug ignition systems). This can be easily determined by scanning the code and seeing which cylinder is misfiring and then moving the igition coil for that cylinder to another cylinder and seeing if the misfire moves to that cylinder.

ok josh it was missing almost like a blown head gasket but no eveidence of oil in water. how do i check which cylinder is misfiring? i dont have a code reader

Without a code reader, it is more difficult but not necessarily undoable... you should try to unplug the ignition coils one at a time while feeling the engine misfire. If the engine begins to run much more rough when you unplug one, then it is working and not your problem cylinder...if you unplug one and notice no change at all, then you have found your cylinder.

Keep in mind that while you are doing this, remember to plug each one back in before you unplug any more
