1) A person who clearly has no idea about how car engines work, but will add up all the engine modifications he has/plans to get with preconcieved horsepower figures to show how fast his car is.

2)A person who looks like hes working on his engine, but he's really just making sure his intake didn't fall off yet and he has no idea what he is doing or what is wrong with his car.
1) (man performing ricer diagnostics) "yea, well the car has 120 hp stock, but i got a intake, muffler, and performance tuner, so its got like 160 hp now, cuz the intakes 15 hp, the mufflers 15 hp, and the chips 10.

2) yea man, theres smoke coming outta the transfuxfibulator there, i just gotta retune my muffler bearings and it should be even faster than before.

Used by "Do It Yourselfer" to find out what's wrong with something. Person that uses Google search engine to check forums and topic specific web sites to find what part they should throw at the problem. Can be used for a check engine light on a car to a washing machine or a PC with the blue screen of death.
My engine light was on so I did a Google diagnostic and all the people on the forums say it needs a putooter valve. I replaced it and my lights still on,wtf
