I think I may have a bad cat since I have low power on low rpm (mainly on 1st and 2nd gear) and when I accelerate, my car hesitates to reach higher rpm. Any thoughts ?

 

could be, when was the last time you changed your coils/wires/ and spark plugs?

 

I did all of that 2 months ago

 

hmmmm have you thrown a CEL?

 

I did have a CEL and I took my car to the dealership and they replaced my shutter valve and my CEL is gone now

 

Lack of power is indicative of a bad Catalytic Converter. Due to exhaust restriction.
After a nice spirited drive stick your head under the passenger side and look at the cat. Is it glowing red? It helps if this is done at night. Does it seem to be excessively hot to you?
Does your exhaust smell different than usual?
Is the PCM throwing any codes?

 

Did you experience a loss of power at higher RPMs before these symptoms came up? When a cat goes bad it will usually effect the higher RPM range, first. Plus, (IIRC) you recently installed a BHR Ignition System. Did you do this because your old coils were bad or because you were experiencing a loss of power prior to the swap? Bad coils often cause the cat to go bad, too.

 

I replaced the coils because mine were worn out bad. I don't remember having loss power in the higher RPM range but as Easy said, my car does get really hot, I can feel it in the cup holders area lol..Does white smoke in morning start ups bad ?

 

Without getting into the details too much (unless you really want to know), I think it is safe to say your cat is wasted.

 

DAMN..It sucks how when I took my car to the dealership when I got the shutter valve replaced I told them all of this and they didn't bother to check..

 

thats the stealership for you, fcken lazy fcks

 

They never leave my car running good, never

 

the mazda dealership by me is pretty good. told about some things and they checked them for me and had no problems.

 

do the work yourself ...or have some of us help you

 

I was telling "dreamtheatermetallica" the other day of how I prefer that BHR customers do their own work and allow me to guide them over the phone, if necessary, as it seems too many technicians these days are lackluster (at best) and people are better off learning this stuff for themselves.

 

Which mazda is that ryan?

 

star mazda in glendale off brand blvd.

 

OH, ok

 

time for a midpipe(damn emission in CA sort of suck though...haha sort of!!!) .....I like how the CA guys/gals are always up to helping out each other with their 8's...not too much of that around here or maybe nobody like me!....haha

 

^ ive been running catless for about 7 months now

 

I had a catless pipe but I had to take took it off because cops around here pull you over for anything

 

or you can just get a aftermarket cat pipe walter.

 

yeah i know what you mean lol my friend in the bmw gots a 4 inch stright pipe.

 

Just curious; did he pull you over because of the exhaust sound or because of the exhaust odor?

 

sound
