I have a 94 Civic D16Z6 that stumbles or bogs on acceleration. It passed smog, just bairly and was running ok . After a couple days it started missing a little on acceleration but got progressivly worse and now all the timeexcept at idle. In netural if you rev slowly seems ok but on more aggresive acceleration it bogs or all the time in drive.The head gasket is new,I have double checked the timing marks and the timing and it is right on. The check engine light does not come on. New fuel filter, spark plugs NGK's,Pcv valve and it's hose,replaced the vacuum lines, plug wires, distributor cap and rotor are fairly new, resistance check on the injectors is within spec and they are all clicking while running under acceleration or not, I removed the throttle body and cleaned it throughly,compression is approx 155 psi across the board. I think that covers most of what I have done any suggestions are welcome and greatly appreciated....

Recheck Plugs, check plug wires again, check the voltage, could be OBD sensors. Sounds like the engine could be getting too much fuel and not enough air.
