anyone i need help please

 

what motor?? what car??

 

you have a leak, you dont need "tune" with just an intake mani and pipe

 

98 gsr motor with 113k miles, there is no leak it only pulses at 1500 rpm no more no less i had a leak but fixed it i dont just have intake and mani also skunk2 stage 1 cams, aem adjustable cam gears fuel rail and fpr header and exhaust theres others but im running stock fuel managment could this be a problem. i wanna get hondata but honestley have no idea what i need!!!!

 

u changed your manifold, almost 100% postivie leak around the manifold common sign, check your hoes, and the manifold itself, good way to see if the manifold is leaking threw the gasket, take some WD-40, or Chem b12 choke cleaner and spray around the awhole manifold, when i say manifold, aim it towards where it attaches to the head,and spray, if it starts to spit and sputter, your either not tight enough and / or you have a gasket leak somewhere and you didn't scrap enough of the old gasket off..try that see if it helps.,,

 

thats what i did thats how i found out i had the first leak when it wouldn't stay running. i just dont know what it could be.
