Re: sluggish on the take off
I would most certainly suspect the fuel filter first. This should be replaced atleast every 10,000 miles. Also check your air filter while your at it . If the problem continues I would then check spark plugs (replace every 15,000 miles), cap & rotor if equipped, and plug wires (replace about every 25,000 miles). It could also be a small vacuum leak.

Test the fuel pressure. With gauge connected to the fuel rail turn key on, listen for pump, when it stops,turnthe key off and leave gauge connected for an hour. The original reading should been 50lbs., if it drops any more than a couple of pounds the pump is bad. The M.A.P. sensor sounds like it was another item in itself.
First thing to check is the timing. It may have jumped a cog, and is giving you all kinds of grief. Next, check for faulty spark plug wires, and or spark plugs. Change your air filter. Change ignition coils. Check tranny fluid level. Check egr. Check for intake vacuum leaks. If your car guy hasn't checked these things, or won't check them when you suggest them.. find a real car guy. Good luck. Let me know how you make out.
dirty injectors.....coil...plugs....where to begin is the better question. Check your plugs...and dump in a bottle of fuel system cleaner. If that doesnt cut it that narrows it down to your coil not firing...or an injector thats just bad. If its anything more serious like a valve not closing thats out of your hands but try these simple tricks first.
