well my van is running really rough barly gut up to 50 kms an hour, so i noticed that one of the 2 fuel injectors is not spraying properly, just lil spits of fuel coming out, so im wondering what brand or if a remanufactured injector would be a good choice, any ideas or suggestions?? i had them cleaned at a shop about 3 months ago as well so im pretty sure that one is just worn out..

Can't go wrong with Bosch.

I would check fuel pressure first. I would also recomend that you change all injectors. Fuel wears them and distorts the spray pattern.

how can i depressurize the system? and any tips on removing the injectors from the throttle body

thanks guys for the info

I would get a service manual for the vehicle before doing this level of service to it. Check with your local library or purchase one.
The troubleshooting section, procedures and pictures will help to guide you. Factory manuals are best and it may pay for itself shortly.
I believe that the system pressure is ~ 14 psi. Have rags to quickly soak up any spills and dispose of them in a sealed can. Use safe fire prevention practices when servicing fuel system components.

Check fault codes:http://www.allpar.com/fix/codes/index.html

ran the codes nothing came up

Some things may not set codes or take an awful long time to finally set. There are a number of things that can cause hesitation. Watching a sensor display on a scan tool may show what is missing. At this point if could be fuel or electrical ignition or an EFI component.
A step-by-step 'driveability' troubleshoot procedure with a meter could help solve the problem.
