i have a b18b in my 95 coupe and i just took the motor out to put a new clutch in and i put it back in and now it runs like **** if i give in more than a 1/4 throttle it will bog out there is no cels idk what the problem could be it ran fine before nothing is different but the clutch.

 

Check all your grounds in the engine bay.

-Thermostat Ground
-Transmission Ground
-Engine to Core Support ground.

You didn't happen to change the Cam timing or anything did you? Put on a new Timing Belt when you did the clutch, etc?

No rags or anything got left or sucked into the Throttle Body?

 

rags in the throttle body would be SUPER CRAPPY. also check ignition timing

 

No Doubt. I've seen it happen though. You stuff a rag in the throttle body to keep out dust, you go to put intake back on while your bullshitting with a friend and don't notice Mr. Rag hiding out by the butterfly. lol.
