ok i got an 04 mt that bobbles around 500 bounces so low that the battery light almost comes on and sometimes shuts off at a stop light not all the time but sometimes and sometimes it'll idle just fine coasting or stopped at a light. but my car stalls when i turn my ac on and dont give it any gas. i can literally turn my car off now when i pull up to a stop by turning on my AC. its weird i dont know what could be the problem the spark plugs and coils have no more then 15 to 20k on them. i've read all the post i can read and have seen multiple issues that can be the case but dont know how the AC can shut off the car as soon as i turn it on. my car also feels like there is a lost a power and sluggish at times but not all the time. sometimes it feels like its perfectly fine and most of the time it fights idle and feels like crap. are these signs of low compression and how much does it cost to get this checked out at the dealership as im at 66k and no longer have the full warranty. thanks for any help possible that can lead to the end of this head ache. oh i recently have no CELs and i recently cleaned out my intake and my MAF sensor.

 

your engine core has a warranty of 8 years/100k miles...i dont know how much the compression check would cost, maybe and hours worth of work...also have you tried cleaning out your throttle body??

 

oh i forgot to mention i did clean the throttle body when i cleaned out my intake and maf... i know i think imma take it into mazda if the bhr ignition solution doesnt resolve this.

 

Does it act up when it's warm/hot? More than when it's cold? How many miles on the engine?
Make sure your engines compression is OK before installing the BHR Ignition kit.
Check that your AC compressor is not failing also. Like the bearing/clutch assembly. They start to go bad and can drag the idle down. But not usually like your describing.
Go to the dealer and tell them you have a loss of power and stalling. Have the dealer eliminate the possibility of needing a new engine.
You might have issues at the dealer with all the mods you have.
Don't just throw parts at it to try and determine the issue. Diagnose it.

 

Put spacer under your hood. Pm me for detail. I have the same problem and this method help out alot. Never stall anymore. This only happen when it really hot outside right?
