Finally found the issue with coolant leaking yay!changed the oil and filter and spark plugs ,suddenly it is missing!!
I is running worse now not better!!what did i do wrong??
The oil pressure gauge is jumping seemingly in rhythm with the miss fire!!help

 

Make sure you:
Didn't cross any plug wires.
Didn't snap the porcelain part on any of the plugs (can happen when they're hard to reach).
Have all the plug wires snapped on all the way, both ends.
The oil pressure jumping would be normal when the engine speed is lunging up and down.

 

Ok thanks!!ill check that out !so far you have been right on every time !thanks a lot!!
