Recommended Posts

Posted

ok well im in school to become a tech. and i was scanning my car for codes today and i got two codes. DTC76, and DTC77, one is EGR2, and EGR3. anyone know what might be making my car have these codes. i have a 95 with the 3100 engine.

 

 

one more question is how hard is it to replace the fuel filter, and how would i go about changing it.

Really, you're getting explainations for EGR fault codes? Hmm... that's new.

Actually, really easy.

All is needed a 16mm and 20mm wrench to unscrew the fuel lines from the filter.

Just watch your eyes; the lines are pressurized and spray gas all over for a few seconds.

yeah thats weird that it did say egr, now that i remember i have a recall on the airbags. id say over a year ago, so the damn dealer prolly fucked it up somehow.

 

 

and atleast the fuel filter is easier to replace than i thought.

Yeah, depressurize the system first by unscrewing the cap on the schraeder valve on teh fuel rail in pushing in on the little pintle thing. Just be ready with a rag there to soak up any fuel.

i know this might sound stupid but where is the schraeder valve at, i know where both fuel rails are at though.

WHen I changed my fuel filter I disconnected the fuse to the fuel pump then try to start the car. Do it a couple times and it will eat up the gas and stall. A little will still come out though, also take off the gas cap (I'm not sure why but I think you are suppose to).
