Ok Mazda 3 brothern!
I am in a serious "Cluster F#$%" and maybe theirs a "Guru" among the forums?? I have the 2.3L 05' S trim mazda, and its got 90K on it and multiple mods, I have the Weapon R Intake manifold, K&N short ram air, OBX 4n1 header, into the stock CATs, with the 2 O2's still operational, they go into a HKS Catback system... With all that in mind, the car has been running well for over 2 years, with the eception of the "lean bank 1" CEL, and the "Intake runner stuck" CEL, otherwise the car was kickin out 245HP, and running good..But now the engine will not go over 3Krpm, at 3 K it or above it starts fumbling , knocking, and stalls out, but if you let up on the throttle quick, it will recover.. and as long as you shift @ 2800 R's you can kinda drive it short distantses, less then 4 miles or so after that it just totally f's up pretty much at all R's... So being I've not encountered anything quite like this I'm asking... no I'm begging for someone with Modified MZR experience and maybe the capability of "writing" to my ECU??? for help, suggestions, anything you think it is?? Oh yeah at the begining of this I replaced the MAF, and "that aint it"...So please HELP..Oh yeah I will pay you for your services if there are any off duty mechanics?????
