Graveyard I will keep you pos t ed and do the same here.I never thought of the ignition module but the rest will get done first.It shouldn't hesitate like that .You can see the Rach going up and down while it jerks a little.But I never heard a fuel pump buzz as loud as this one.KEEP me posted also.

 

I want to thank all who is helping me response wise to figure out what is going on with my blazer.I plan on putting in the plugs,wires,cap,and o2 sensor.I hope this does it for me and I know I need to change the heater blower also due to the fact the climate control isn't working and it was the wrong blower put in.It called for this type but it is minus a plug in.It just constantly blows got heat with no control of having it blow cooler air.So that will be replaced by a a.c. Delco blower.As far as the hesitation I gotta fix it it.Has mileage is terrible and gotta take care of this.
