i have a 92 civic 4 door with a ls b18a1 block an gsr head. It was running fine until the water pump went and was leaking coolant down the side of my block. I changed that and checked the oil for coolant it didnt have any in it, so i drove it and it was fine until it fauled my plugs an i figured with the coolant leaking on that side with the timing belt it made it skip, i reset the timing its not fauling my plugs anymore but when i start it the car stalls unless i keep my foot on the pedal. My thoughts are maby lack of fuel pressure from junk in the fuel filter of maby my fuel pump just went bad, anyone got any ideas i dont want to spend money on stuff if thats not what it is.

 

Did you time your ignition timing with a timing gun? Did you re bled your coolant system?
The cooling system plays a big role in your idle as well. Double check and make sure everything is at TDC.
