engine trouble!!! Help

[paweljelop]

Few weeks ago i asked ppl for help on a exhaust system and I put a vibrant exhaust on my 05 mazda 3, which sounds great, now im having engine problems. I replaced the left mount on my engine next to the coolant, but my engine still shakes to much when im idle (on red lights or standing still in one place) When im on red lights i can feel the car shake, not vilantly, but i can feel the car shaking a little, which in other cars i don't feel. I need help to figure out what the problem is.....

it might be your intake wiring harness i know its just wires but mine just went on my 04 3 and it ran like garbage or it could be your rear motor mount that is shot jack the car up and have a look and see you cant miss it its right after your down pipe good luck

Did you replace the side engine mount with an aftermarket one, or a new OEM one? Aftermarket ones will shake pretty bad, and that's expected/normal. Also are you sure you're just not feeling the rumble from your new exhaust? How bad is the shaking?

well i checked all my wires and they r fine. maybe its the motor i have to chceck, i just put in a new lightweight flywheel and a new clutch, and i did replace the left side mount but it still shakes, i replaced it cuz it was shaking but its still doing it. the shaking started way before i got my exhaust. the shaking comes and goes it shakes more sometimes and less the other. it really started happening after my belts broke and my car had to be towed. idk wat it could be, but ill chceck the motor...
