purge valve is pulsating at idle rapidly open and closed... if i unplug the connector and take a test light from battery negative to plug hot wire it steady glows with 12 volts... if i take the test light from battery postivie and touch the computer controlled ground wire the test light pulses as the purge solenoid would be doing... is this normal?
Thanks for the response.. the only scan tool i have is a blue driver scan tool so it doesnt allot me to view things like that... some live info but nothing like that
