ok so yesterday i did my valve lash on my 93 si with d16z6, now i start the engine up and it idles real funny, it stays at the general same spot when it first starts up but wavers +- 50 rpm or so, when the car warms up a little it starts waivering more and sounds like it wants to die, is it a vaccuum leak or what, also the engine seems so be moving a lot more at equal intervals it shakes a little, i will try to get a video of it up soon so you can see easier, thanks for any help

Got the same problem, with the same car? hope someone can tell us

 

check you Idle Air Control Valve. unplug it if it cause idle to increase it ok. if not that your problem. Also check to see if your tps see if it get like .5 when close throttle. and check for vacuum leaks

 

re-check your valve adjustments..

did you do it when then engine was atleast under 100 degrees? and the correct lash?

If so then re-set the ECU and see if it changes

 

ya i redid the valve lash and it was cool (less than 100 degrees), i will reset the ecu and see if it changes anything, it sounds really lumpy could it by the cam? i've had it in for awhile now its a zex 59300 cam, once i rev it past ~2300 all the problems go away so i dunno but i will reset the ecu and see thanks
