Horrible, like what conditions now? You change plugs? Horrible miss at idle?

 

[96TAHOE215]

no the plugs werent changed and its rough at idle and while driving could the timing be off

Are you throwing a code? When I did my gasket I put the distributor a couple tabs off on accident and it threw a code while running like crap

If its still losing coolant, it could be a head gasket. If its gotten worse, could be a cracked head at this point. Check for coolant loss again.
