On an 2003 gmc envoy....this was after a water pump change out....could there be an air bubble in the cooling system...??
After changing the water pump on my envoy it didn't want to start everything was dead except the dash informational lites...I disconnected the negative terminal of battery as instructed before starting the project...
thought I really messed something up really bad...didn't know what to do so I disconnected both terminals...waited a breif period then reconnected then...car seamed to return back to normal...except it won't idle with a/c running...rpm surges then slows until finally stalling out...pls help...THANKS
