...jazzmaster ..

Customer: replied 1 year ago.

as instructed by the scaner one time with it running and once without running

Expert:  jazzmaster replied 1 year ago.

is the truck running bad ? hard starting etc.

it shouldn't be showing a 3 digit code though

did you try clearing the codes and then seeing what codes come back ?

Customer: replied 1 year ago.

truck runs good on idle but as soon as you tap the gas it want to stall but if you push it all the way down it runs ok and did clear the codes to duble check what it was showing

Expert:  jazzmaster replied 1 year ago.

does this have a low idle or was at low /below idle for a period of time

some of these codes are for an egr issue

does this have an air pump on it or air diverter valves ?

what kind of scanner are you using ?

,also give me about 15-20 minutes ,I need to look up some things..thanks

Customer: replied 1 year ago.

idle was fine it was when you would tap the gas it would die out but if you pushed the gas down it would die out then rev and for the air pump or valve idk what it has im working on it for some one

Expert:  jazzmaster replied 1 year ago.

ok, ,check the fuel pressure and if you haven't yet check the fuel filter .I wouldn.t worry about the codes for the time being .one is for the knock sensor and that is not to be concerned about unless the was pinging going on.

the egr valve may have some carbon on it (clean that )

but lets focus on the fuel filter and fuel pressure -I believe the fuel pressure should be around 35-40 psi .

and spraying out the throttle body with carb cleaner ..
