Hi, I have a 94 honda civic ex coupe automatic its all stock with d16z6, I recently replace the dizzy and it ran perfect. Its been a month now the motor started act funny when its warmed up, if u open the throttle in P really quick it hesistates then picks up rev. and if your in D and hold the brake down the motor will have a quick irregular shake then idle normal again. I have swap out a new dizzy with new cap and rotor, check the spark plugs. check the belt timing, swap in another map sensor. No check lights. Any idea's ? Iam aiming at the fuel system next
And also i cleaned the Iac and TB, same thing all mounts are fine no rips it never did this before, kinda strange Thanks.

 

Check your grounds.
