car wont revv on flat ground?

[Craving4Boost]

for some reason my car wont revv on flat ground. when i try to revv it the rpm at idle would just drop and want to die. i had a similiar situation with the same feeling of the gas pedal when i had too much oil because the oil would clogged up the turbo not letting it spin as a result letting no air into the motor. at the time i drained the oil and my car started to revv again.

this time its not oil because i drained the whole thing out because i was pissed and i put 2 quarts in and still would not revv on flat ground. the reason i say flat ground is because if im going down hill..up hill...or my car is jacked on EITHER side...it will revv JUST fine. but when i get off the hill or unjack my car...my turbo sounds clogged again.

i thought it was not enough gas but i put in gas(because it was down the hill) so i could drive it. but once i hit the gas station and tried to leave, it wouldnt work...my rpm's would just drop and want to die.

if you guys remember i blew something back then..i thought it was ringlands but i think its the headgasket now because i have white smoke...(not crazy lot) but its coming out my exhaust constantly. looks like my car isnt warmed up on a cold day or something. i was thinking maybe since i have a blown headgasket the coolant is clogging my turbo up since i elimintaed the 2 of 3 liquids (oil,fuel). maybe its the coolant.

help me out guys....there has to be a connection of why my car slanted runs normal and on flat it doesnt

oh yeah and a week ago...even though i cracked ringlands/ or blew a headgasket....it was still running normal

the only thing i did today was change my wastegate spring, changed the wastegate gasket

hmm for some reason when i let the car cool down for a while its able to drive again. when i cant drive it the check light comes on so i use it to know when i can drive it or not. i should really find out what i blew

It just seems like the problem would have to be related to fuel. I just dont see how it could be anything else. I have honestly never heard of anything like that before. But just to maybe eliminate the blown headgascket possibility:

Does it over heat?You said that white smoke was coming out of the exhaust, check to see if it is steam. Run your finger around the exhaust to check for moisture. (remeber that if the weather is really humid it might be a false sign)Check your spark plugs.And finally start your car up open the radiator-cap and when the thermastat opens check for bubbles. In some cases the radiator fluid tends to spew out(not flow out, but more like a geyser...lol)

hope I helped some....
