My GPs have been doing something unusual the last couple days. Previously, when I would start the girl up the GP light would come on about 3 or 4 times for 3 seconds each. That's what I know as 'normal'. The last couple days after I start it, the light stays lit for 6-8 seconds, just one time. I have the Heath ECM in it now, if that makes a difference. Anybody experience the same thing? Is my GP controller about to sh!t the bed?
