3800 rpm flatspot?..Cure?
I have seemed to run into what,I guess you guys call,"the 3800 Rpm Hesitation". I've tried timing, grounding coils, engine, body, Ecu...new plugs wires and air filter, ran an engine flush and injector cleaner...hints please 
If anyone can elaborate more on this issue I would be most appreciative.Thanks.

Have your fuel injectors professinally serviced. 3,800 RPM is when the secondary fuel injectors kick on.
I've had great experience with WitchHunter Performance -> http://www.witchhunterperformance.com
It also wouldn't hurt to clean all of your grounds, replace the fuel filter, replace the fuel sock, inspect your fuel lines, inspect the fuel tank and fuel pump, check the fuel pulsation dampener and the fuel pressure regulator.
Once your issue is resolved... Redline your engine once a day. It will get fuel flowing through those secondary fuel injectors and it will break up some of that carbon build-up in the engine.

Thank you! I was reading through the forum for posts that address some of the problems I've been having. I have the 3800 RPM hesitation too, but it's not every time. Then again, the car has had 10 owners before me. Again, thank you!
