Loss of power

[iX-treame]

So I feel that ive lost some power, doesnt push as hard, mostly seems like that in the lower RPM range but still feels different in mid and upper RPM's as well.

Ok so here is the train of events:
-Seafoam-> maybe knocked some shit loose and caused a clog?
-Oil light->dipstick was popped out and i had lost oil, but my friend thinks he may have left it like that, but maybe pressure built up?
-Slower to crank up and almost sputtery sometimes
-Pretty unresponsive in low gears, when floored it seems to take longer to rev up(not dry rev) and get up to speed

Hose that realeses pressure from crankcase clogged?

So i have no idea, please give me things to test and look at and ways to do so.

Thanks.

vaccum leaks?

vaccum leaks?

ive looked for them but that's not much, is there a better way for me to test for them?

[xwill112x]

since you have a m20. i couldnt tell you where to start..

but just look at all your rubber hoses and connections accsociated with them.

then maybe check your rotor and cap?

Patrick a good way to test for vacuum leaks is to start the car and remove the valve cap and if the car starts runing poorly you have good vacuum pressure if your car runs the same you have a vacuum leak

use starter fluid to find leaks
