so i got a crack welded on my cat and they broke and replaced exhaust manifold studs or something...well i drove it home and it is M6 when i would take off, 1000rpm minimal and it felt like it was pulling against me or something. also this was weird 6th gear 1000 rpm 50mph and given alittle gas the whole car bounced and 5th gear the same, and 4th gear at 50mph would i guess not respond and pull on me negatively, also it was slower. my uncles shop did the work and some of them drove and said it needed wires and plugs. are my symptoms matching?
