i have an auto 04 bought it used so i dont know how well the air condition ever worked but it seems as if my air condition is not cooling enough but the air is blowing good. when its hot outside and i have my air condition my car rattles but only when its hot out. also sometimes when i come to a stop and once again its hot outside my car will just shut off and i have a lil hard time starting but i turn off the AC and rev up the engine and its back to normal...and in case you were wondering yes i did already get the new engine DOES ANYONE KNOW WAT MIGHT BE DOING THIS CUZ ACCORDING TO THE DEALER EVERYTHING WORKS PERFECTLY FINE ON MY CAR and im getting tired of dealing with them

 

personally sounds like a new engine is on its way again....should not shut down at stop lights with a/c on....take ti to dealer and have them do a compression test on it

 

Use heavier oil than 5w20 garbage, say, at least 5w30.

Change all plugs and coils.

If it still like that, bring it to dealership said u "did the proper maintenance already" show them the receipt of coils and plugs and oils u brought and tell them to test the engine for compression.

Ask em if the 09 models do this as well.

rough idle.. stalls.. hard starts.. all signs of bad motor.

 

wat do u recommend?

 

convince the dealer (or mazda na) to run a compression test on that bad boy

The cabin is too hot from the tranny and engine for the A'C to compensate. Known fact.
