ok so i replaced the head gasket and put new motor mounts in, but when i went to test drive it...

1)It sputtered everytime it got from 2500-3000 RPM and occasionally backfired.

2)wouldn't go past ~3000 RPM in gear, in neutral it would revv to about 4000, but no more

3)When i put the pedal to the floor it does nothing...possibly backfires, and actually loses RPM

4)Anti-Freeze was all over the intake side (im checking the coolant hoses tomarrow)

I'm thinkin it might partially be my jacob's electronics ignition system...im saving up to replace that...but other than that i can't figure out what the hell it is. I checked to see if there was any water in the oil, and vice versa, and it all looked good. If u can answer any or all of the above, i'd be happy, thanks.
