I have a question.

I was at dealership last week, I told them that I have lost of power issue and :

"CUS STATES CK INT NO POWER ON ACCELERATION
VERIFIED CHECKED CAT GOOD FUEL PRESSURE GOOD CHECKED IGINITION FOUND ALL PLUGS OLD STYLE FOUND COILS SENDING ERRATIC SPARK @ LOAD AND HIGHER RPM R+R COIL R+R PLUGS
RE ROAD TESTED VEHICLE STILL FOUND SMALL HESITATIONS THROUGH RPM BAND DECARB MOTOR REROAD TEST NO MORE HESITATION"

Notice : I replaced all my plugs myself less than 5K miles ago and coils 3 K miles ago.

hmm ... it was nice that they decarb, all 4 new plugs and 4 new coils without me fighting for it (Thx Wayne Mazda!)

but I really wonder did they checked the fuel pump pressure.

cuz now my car chokes even below 6K rpm. sometimes as early as 4K rpm. and it happens if I rapidly accelerate or full throttle with less than 1/2 tank of gas.

I have a new fuel pump in my garage, should I just order a new gasket and quick release connector and install the pump myself ? or bring it back and bug them to replace the fuel pump ? or maybe the resistor ?

I ask becuz Im kinda lazy to change the stuff back to stock(thats what they told me last time), is it worth it ? :)
