guys what would i need to do to fix the spark knocking in my 01 tacoma dbl cab with 3.4 yeah i know premium gas or octane booster buy what causes the prob and how to fix. also a hear a very light tickin sound wich seems to be coming from driver side. also i was thinking of maybe installing a 2 inch body lift is that possiable with the auto trans. thanks

 

New spark plugs? Im a big fan of sea foam as well. Smoothes out all my engines.

 

Yeah, seafoam and a complete tuneup is where I would start.

 

I have a 2" BL with an auto trans, you just have to adjust the shifter when you're done which is simple.

 

maybe try changing where you buy gas too, some people always buy from the same place, and it might be crappy gas........just sayin
