Re: Car is shaky and rev is dropping when driving
Just bought the spark plugs, but have a few questions before installing them tomorrow:
1. On the box, it says not to gap. The new spark plugs are around .041, but my owner's manual it says .043. Should I gap it to the manual's specifications or leave it as is? If I gap them and they are .001 off, will it affect engine performance?
2. It says not to use anti-seize on the box. I heard that white metal spark plugs, you don't really gotta use it or should I?
3. I don't have a torque wrench, can I just tighten it until it is snug tight? I know the cover it aluminum so I shouldn't put it on too tight. Should I buy one because it's important
4. My manual says Denso or NGK, but I accidentally bought Bosch, but the Autozone website says this will fit my vehicle and it is iridium-tipped. Should I install?
