Fuel Injectors Problem

[Rick Werneburg]

I have a 2003 Toyota Rav4 (76k miles)and have received an error code P303 indicating
multible misfires on cylinder 3. The car seems to be running fine. I have reset the code several times but after a day or two it comes back on.
I have two questions. The dealer says all four injector should be replaced at the same time. Is that necessary? They want $300+ to replace one and $830
to replace all four.
Is this something a do it your selfer can do with out special tools?
Thanks

Hi Rick,
It`s an easy enough job to replace injectors get yourself a workshop manual it will give you a step by step guide to this job and many others, if you can use a wrench to repair a bicycle then you can do this job, also go to an online site to purchase your new injectors if you dont get a full set for under $200 I`ll be very surprised, or you could simply get your own serviced at a local diesel pump/injector service centre they can run a test on your own injectors on their test bed and can also service them if needed hope this helps

Thanks Heavy Oil,
Should I be able to get a work shop manual in an auto store or online.
Do you recommend any perticular websites.
