my 94z doesnt seem to be running at full, ive changed oil, oil filter, ran fuel injector cleaner, supreme gas, and cleaned my k&n air filter. im in the process of changin spark plugs to E# diamond fire. ive heard changing spark plug wire will help alot. i just need to know if finishing the plug change and replacing the plug wires will help that much. also car bogs down quite a bit.

 

If it needed the wires and plugs, yes it will help a lot. I know they are hard to get at but you need to finish the job. Go from the top and the bottom. After you do it once, you will be able to do it in around 45 minutes. DOnt get discouraged.

 

check the connections on your knock sensors. try unplugging one and see if it makes a difference. jjz is correct if u have bad plugs and/or wires it can make it run like crap.

 

might wanna change the fuel filter too.check for any stored codes

 

try cleaning your maf sensor. that's what caused mine some serious issues.
