Hey everyone I'm trying to fix my 2001 ranger I have done everything except replaced fuel injectors O2 sensors and catalytic converter. I have a new fuel pump in it new maf sensor new TPS sensor. My issue I'm having is when it's cold and I let the clutch out slowly and give it half throttle its struggles badly and barely moves once it warms up it's fine but on heavy throttle it's still is hesitant can anyone help me figure out the issue it would be appreciated thanks
