so im still strugglin with this dumb civic, its a 94 civ cx with a d16z6, i fixed the eratic idle, but when you punch the gas, almost every single time it studders, and jumps a little, not severly, and eventually it goes again. i pulled no codes out of the ecu, so im kinda lost. i switched the map sensors, no change, changed the fuel regulator on the rail, did nothing. kinda stuck. and its got a new ignitor, cap rotor wires and plugs. all grounds good. im pretty sure it isnt a ignition problem, maybe its runnin too rich, ill pull the ECT sensor for the ecu and see if its built up with calcium but i doubt it!
