Need Lots Of Opinions

Recently my car has been sputtering and bucking at idle and driving. dipstick popped out twice..compression test revealed 155 on cylinders 3 and 4 and 120 and 90 on 1 and 2. No coolant leaks...sparkplugs were awful looking so i replaced them...some oil on the old ones...when it warms up it seems to run better but still not very well...barely idles in cold...when you drive you have to keep it boosting or else it runs rough...any ideas?

doesn't burn oil either...runs so ridiculously rough that i wanna cry. im thinking rings but why does it run a little better when warmed up?

The reason it runs better when its warm because the pistons and rings expand and seal better. This prevents oil from getting by, when your car is cold oil probably gets by on that cylinder with 90 pounds of compression.
