My 2000 kia sportage has no power and I think a vaccuum leak somewhere around the canister or canister close valve. I can rev to 1500rpms but after that it sputters out and will die. What can I do? colud it be a problem with the fuel demand not being met?

check the idle air control valve. if that's faulty, it can cause such symptoms as described. if that's OK. do check the transmission oil. if it's low or there's a leak, causes problems as well. I hope this helps.

It is important too identify the following:
1) The source of the exhaust leak
2) The source of the oil leak.
The exhaust leak could turn out to be a bad exhaust gasket, a cracked or loose exhaust manifold, a cracked cylinder head or bad gasket, or related parts. The oil leak could turn out to be the valve cover gasket. A dried out valve cover gasket can cause oil to sit on the spark plugs and have oil leaks. Be sure not to over-fill the oil. A machine shop can find cracks in cylinder heads. If these problems turn out to be ok (and one of those stethoscopes may be helpful) then you could procede to check fuel delivery. (there will be pressure in the lines) A lot of times connectors get corroded. I noticed on this model the sensor for the engine cooling mounted near the thermostat is very sensitive to variation. Same for the air sensors if left loose.

cad converter. take it off first and see if it works better. if not check injectors.

rectify loose/ cracked hoses. check if the canister is in the vicinity as it may have a problem with the purge valve / solenoid.

The canister purge valve is a computer controlled solenoid valve that allows any stored fuel vapors in the charcoal canister to be recycled back into the engine combustion process. The valve is typically located on or near the throttle body. The canister purge valve is controlled by the power train control module (PCM). The canister purge valve is closed each time the power train computer runs the OBD-II (Onboard Diagnostic Generation II) EVAP monitoring self-test.--------------------------------------------------------------------------------

Sounds like an air leak or throttle prob. Use brake cleaner around all hoses & manifold (intake) and see if it revs up. If so locate the air leak

in the rear near the fuel tank look for a black box its near that as well

P0505: Idle Air Control Valve System fault, Code P0505
-Vacuum leak
-Dirty throttle body
-IAC motor defective
-Poor electrical connection to the IAC valve, hope this helps and good-day !

Have your vehicle checked for a vacuum leak . that would be the most probable cause

Clean out clogged fuel injectors
