i have a b18c1 motor in a 94 civic. scotts machine shop bored the motor 25over and put brand new itr pistons in and the head is milled because the head gasket blew before scotts machine shop. the motor is now in the car. when we crank it, it back fires and spuders, and the sparkplugs are wet with gas. the timing is right and we replaced the distributor, new plug wires, replaced injectors, changed map sensor. allso its runing a skunk2 intake manafold insted of a gsr one, with a p30 ecu. the ecu is only throwing a o2 sensor code, compression test says 125 on all cylnders........... please helpppppppp!

only 125??? sounds like your losing comp somewhere, my gsr with 150k miles on it pulls 200 across all 4 and yours has higher CR pistons so....

 

Popping and sputtering is an ignition problem. Those compression #'s are terrible. I have a 99 GS w/50k putting up 200+ across all 4 cylinders. If the plugs are that wet the timing probably isn't on. Try unbolting the distributor adjustment bolt and move it closer to the firewall or closer to the radiator until it idles a little better.

 

125 each cylinder?

 

ill take the tranny
