alright guess I will check out the EGR first then see what happens... How about the air intake sensor where is that,, Thats code 41 just in case

Thanks man that was helpful ,, now I got the code 32 and 42 EGR function and fuel temp sensor I know where the EGR is but fuel temp sensor I have no idea where that is... looking for it now

Ok I got a 31 EGR function code and a 41 intake air temp sensor,, Any suggestions I got the type the type you just turn the screw clockwise and back again..

Ya I got it I would hate to have to change that fuel regulator But like you said just felt around and I got it.. looks harder then it is... but of course it still missing so bad any suggestion on getting the diagnostics test I tried the one under the seat all those lights just freak me out !! I will just take it to a pro,, will any diagnostic do or what questions should I ask the Tech.. and if there is more then one problem how does a Diag tell you what to start on... I need this babe to run good... I hope its not the injectors I would have to do that myself and taking of that top manifold looks like a bitch why did they have to put that 1 injector so far under the manifold Thanks for any advise I could sure use it.. also who ever owned it before TACOED the skid plate bad...

K will do.. TY Ya it was full tune up, u know where they hit you with 110 for everything ill do the codes after I replace line...

Ya full tune up and gaped right..

Ya I can feel where it goes. do you think that missing hose can cause a bad miss when there is a load on it ? And thanks for all your help..

Hope I'm Putting this question in the right place, If not sorry just move at your Leisure.. Ok My hose is missing from that fuel regulator way in back of the engine. you know the one that hooks up to the upper manifold, What a pain,,, anyway the truck misses real bad with any load on it, I know i'm going to fix this. but How much do you guys think with that hose missing will it affect the performance is this a real huge issue. I can not fix today. starts fine it misses real bad with any load on it... Thanks for your help with this, I just bought this pathfinder changed all plugs wires cap of course the guy a bought it from said that all it needed.. any thoughts i'm all ears,, Michael..
