Hello everyone my name is Pedro im currently working on a 98 civic with lsvtec. I have tucked harness with ultra series manifold, aem fuel rail, plm headers. The head has been ported and polished as well as all the goodies has stage 2 skunk2 cams. Having issues with it cutting out or bucking when i first get going once i get it passed the initial hesitation it runs great till till i let off the gas then bucks and cuts out again it then clears up again checked timing, fuel, and spark everything's good only thing I’ve noticed is it leans out during the bucking. I should mention no cel codes and im running a s300. I’ve recently started doubting the TPS going to calibrate it as soon as a i buy a new ohm reader as i misplaced mine. Just wanting to get some ideas of what i should check tia!

 

Is your CEL illuminated ? If so, what codes are stored ? Who TUNED the car ?

 

I have no cel light on. And i have bought a basemap from hondata to my specifications should be close enough to tun properly for a tune but not the case.

 

Does your check engine light work ?
