Hello All
I have 2005 mazda6 2.0L. i am in Abu Dhabi, UAE. I always maintain my car with proper way and always use premium oil. from last 6 month i feel little jerking(on parking/traffic signal) on the engine when I use AC and car is on N/P or even in idle condition on D.

one mechanic told me to change engine mount. i changed changed mount but problem remain. then I have changed spark plug but even it remain. now mechanic told me to change the Fuel Pump, others said that it's the problem of some sensors. i am confused now.

i am really tired now. i hope somebody will give me a proper solution as soon as possible.
Regards

Sorry I forget to mention that....engine in jerking and rpm is moving from 750 rpm to 900 rpm...once goes up and falling down again.

Hey bro... Im driving a 2003 Mazda 6 in Abudhabi as well. I faced this problem as well. But this was after i changed my AC compressor. It could be due to the AC gas on a low level. I re-filled mine and startd off better.
Btw How much did the engine mounts cost to change? i need to change mine as well. They are getting old and u can feel a lot of vibration.
Thanks and cheers

Hello dude...i have fixed my problem...it's running awesome now....I just change my all "Spark plug wire" (only 150) and its too cool now...mechanic told me that it happens because one of my plug wire was damaged and start misfiring.it feels only in low rev as other 3's are running fine....nyway..there are 3 mounts in Mazda6 and it costs 550 in total from Popular.

have fun....
