ooooooor if only there was a thing that used these fancy devices to run and had all this fancy circuitry and programming to pulse them perfectly.. hmmm wonder what we could do.. OH I KNOW! A F*CKING CAR!

OP
Remove bolts
Remove Injectors
Install New Ones
Replace Bolts
Start Car



Does it Run?
No --> Bad Injectors, see step 1
Yes --> Drive, enjoy.
