So, i recently got my car serviced with balance shaft belt, 2 idlers, crank sensor, timing belt, spark plugs, ignition wires, and ignition coils. And now when i drive my car and accelerate it to about 3400 to 3500 rpm i get this rattling noise from my engine then when the rpm surpass that range i dont get any noise anymore. I really dont want to take it back to the shop and have to be charge for a diagnose but im thinking it could be serpentine belt or loose of the down pipe. Any suggestions?? It be really nice if you guys can help me.
Thanks.
Thanks.
