Cold Start Valve?? A myth??>>
Turns over, and roughly spikes and drops rpms. If driven a short distance afterwards (as it usually is, my work commute is 1.5miles) you can hear a "knock" sound coming from the fuel tank area..i'm guessing from the pump.
About 5 or 6 "knock knock knock"
Someone suggested a cold start valve for my starting problem. could it be the source of the knock???
is this valve a myth?? does it exist??? where is it?? and who sells it??
TIA!
