2003.5 Mazdaspeed with deadly miss!!!!!!

[Radical Radick]

What to do people my MSP has 11k on it and it's had the miss since I bought it. It has been flashed, It's been to four different dealerships and they can't fix it. The miss usely happens about 3200 - 4500 rpm under a load. All the dealerships have gave up. What to do???

sounds like it should be re-flahsed again......do you have any CEL's? Check those out. Mine threw a "Random Multiple Misfire" CEL and then the motor grenaded.

I have never heard the hesitation called the "miss". new one by me

 

[KyRaceFan]

by missing, you mean a spark plug misfire?
try new plugs, wires, and if that doesnt work, a new coil.
But in the rpm range your talking about, its probably not missing, its the hesitation.
Get it flashed again, or just buy a cheap boost gauge and mbc, and tune it for 9psi.

Your car is acting like the large majority of MSPs ever made. Trust me, I don't like it either......but that's just how it runs!

Consult your state's lemon laws contained in your paperwork from the dealer.
