now that thats pertty much takin care of... i have an egr code...

p0401

i was told that it means the PCM has determinded that there is insufficient flow in the egr system

well then i was told that it could be ether the vavle is clogged or that there is a failed valve or faulty solenoid any way i can diagnose this without buy the parts and switchin them out..

sorry to not get back sooner but it was a simple fix.....

well i RTV it back and i guess i used to much becaue about 1/8 of the whole was the only thing that was open..

put a real thin layer on it and sealed it up no code since..

also changed out the cam sensor changed it so far no code...
