My car has no pick up

i had same problem,i had spent a lot of money on new coils,platnum spark plugs,and spark plug wires.But you what my mechanic asked me if they were bosch parts,aand i said no. that was the problem i installed all bosch parts for more than half of what i spent before.Its running like a champ,IT DOES MAKE A DIFFERENCE IF YOU USE BOSCH PARTS.
