I have a 94 grand prix i showed my husband sparking at the plugs and wires so he put new wires on just those 2 and ever since he did when i give it gas it has a knock in it and won't get up to speed until you get going but still runs bad and when you stop then take off it has the knock in it again until you let go of the gas, he was told that the wires were on wrong but he switched them and still the same but he knew he put them on right because he did 1 at a time, can anyone help me,my husband doesn't want to keep putting money in it if it's going to shit. Could autozone have given him defected wires or the wrong wires for a
94? Thanks- posted
