how can i fix a lean fuel mixture on a 99 dodge dakota 5.2L

 

are you getn any codes?

 

no but im getting spark knock and ive been told that it could be because of a lean fuel mixture , so if theres a way i can adjust it then i can check and if it doesnt work then i can cross that off and go the the next thing that could be cause my spark knock

 

go to the secnd gen dodge ram sec. at the top it will say end all be all plenium gasket. read it man. it will tell you every thing you need to know. i have the same problem. hope this helps you

 

yup, i looked there , i cant tell if its my plenium , i posted there its the last post but no response, and when i look down my throttle body i cant really tell if theres oil or not and yes i used a flashlight, and i only have 1 of the symptoms wich is spark knock no loss of power of wich i can feel, and very little oil loss between oil changes

 

well i have the same symptoms. i havent really lost any power that i can tell. but if i get on it to hard it will start to spark knock and i run 10w40 castrol so i think its a lull to thick to just run out a lull leak. if you know your way around the truck pretty good. pull your throttle body off and take a better look. i used a cloths hanger and a shop rag and ran it down the back of the intake. when i pulled it out it was covered in oil. i cleaned most of the oil up and it ran pretty good after with no spark knock. but it came back after.
