2007 mazda3 auto, no power uphill, jolting, gets stuck in gears
I was driving towards the city when my car begins to jolt while going up hills. And while jolting it was losing its power, hit a hill on the freeway and the car couldn't get past 80km/h. We had to drive it home somehow and it seemed to be getting worse. Just made it back to the mechanic. First one said it was an oxygen sensor issue, so then I decided to take it over to another mechanic. Then this one was saying it was a crankshaft sensor issue. He cleared the codes, took it for a drive again and error codes came up for mass airflow sensor issue.
So he replaced the MAF sensor. I picked up the car but driving it didn't feel right. Accelerator was extremely touchy, and I could see the revs fluctuating erratically. Once I got 30kms into my trip, I went up a hill and lost power. I had my foot on the accelerator but it had gone down to 20km/h and was stuck in 2nd gear. Taking it back there soon but he thought he was on the ball with the MAF sensor problem.
Any ideas??

Still isn't good, need some answers. MAF sensor was replaced as well as the fuel filter. Took it on a decent drive today and earlier on it was revving higher than normal (about 2500rpm while cruising at 100kmph). It was also struggling to get up hills and taking a lot longer to change up gears and gain speed. About 50kms in, the engine light came on. Currently waiting to get it scanned again. Any ideas on what it could be?
