Hello, I am going to explain to you the best I can so please bare with me. 

Also with that being said, I hope it is not to much info I am giving you, 2 of the 3 mechanics or technicians said that I told them to many issues at one time. (I know right what the hell is that all about I am used to a real mechanic you tell them what's wrong regardless of the engine e light and they fixed it) 

The first mazda dealership wanted to charge me almost 1300 dollars and told me they could not guarantee that it would fix the problem!!!

I also bought the extended warranty the best one I could get maybe this is why they don't want to invest time into my car im not sure.

I have a 2015 Mazda 3i Touring, 61,000 miles on it, manual 6 speed transmission, with a 4 cylinder skyactive engine. 

I need your help I live in las vegas it is so hot and I need my AC, but I can not use my AC because when I have it on the car starts tripping, rough idle, it feels like it is slipping when I am taking off, every once in while I hear a weird (I want to say grinding noise) when I am in first gear maybe second but for sure first gear, the car wants to literally die or stall whichever they are the same to me. I literally can see the rpm's fluctuate when im at a stop light.

The other day while in neutral at a drive thru it stalled twice I felt a really hard jolt. Also it will jerks when im in first gear and taking off no matter how much gas or how little gas I push or when I do or don't do the transition thing.

Here is the weird part the minute I switch the AC off the car mellows out, the transmission and shifting are all back to normal.

Look they tried telling me it's the gas it's not the gas. I have been putting gas at chevron and pumping 89 like I was instructed to do.

Maf airflow sensor was changed a couple weeks ago, as well as the hydraulic belt tensioner (apparently all the fluid leaked out of the hydraulic belt tensioner so it was replaced).

I have had this car at 3 dealerships in the last month.where and 2 of them were mazda dealerships, apparently mazda technicians talked to the manufacturer technicians and not one of them knows what's wrong. 

There is no engine light, the one time that there was and I almost died getting on the highway (because the car started tripping and would not accelerate hardly at all) the code was p130c, but replacing the maf sensor apparently fixed that code. There is no longer an engine light present on the dash. Also when this does happen the "bsm" light goes on off (I'm not sure if this is important or not)

Also when I bought the car last September I only had it 4 days and it started tripping doing what it is doing now, and when I took it to the dealership they had it for a month and stated that they changed the clutch ( I never received paper work never signed shit they gave me my keys and off I went) it was already cold when I got the car back I did not need the AC the car ran great all winter, not one problem. The minute May hit and I needed to use the AC that's when my car started tripping. 

By the time I finish paying for this car it will be over 30,000 dollars, i should have a working AC, this is insane its so hot I can't even puck up my grandbabies a d take them anywhere with me. This is holding me back from so much. 

Please help

Thank you for your time,
