you need a special star socket ... to Take the fuel rail off ( I think its a T30 or T25 ) ... But there nothing else you need ... just put it in and something to reset the ecu... like programmer or something

Can you do the reset with an OBD-II reader after you replace the injectors?

One tip on pulling plug wires- you can buy an inexpensive plastic boot puller that has a "T" handle and fits over the boots. Since it pulls the boot from the bottom near the block, they come off easy.

It's one of those tools that you'll wonder how you ever got by without it.

HUMTECH is an unknown quantity at this point
Default Re: P0300 troubles

Only problem with that is you cant grab the base of the boot cause the tin heat sheild covers most of the boot and cant be removed until the plug wire is off the plug
