Hey all so I have had a issue with the car where the car won't idle the needle just bounces from 3k to 0 and when I could drive it I'll be doing 100km and all of the sudden it would jolt like I slammed on the breaks. we did take it to a mechanic and all the did was Clear the codes and replace a few sensors and said it was fixed. I now can't take it out of my drive way because it's doing the needle thing and the stalls. Any help would be great thanks

 

Did the mechanic tell you what the codes were?

What sensors did they replace?

I would suggest googling for a mobile mechanic to come round and scan it for codes again. or else, tow it to Mazda.
