hey everyone my camrys sprung an oil leak just behind the drivers wheel and when i start it, it hesitates and idels abit all over the place from 1200rpm then down to 800rpm i know thats normal from the auto choke but then still idels abit ruff and if i give it a rev and take my foot off the pedal it some times stalls could it be the spark plugs? help would be greatly appreciated.

Yeah, it could be plugs & wires if they haven't been changed in a long time. What model year & engine do you have?... any recent maintenance done?... more info helps. Plug change interval varies a bit depending on which engine, but 100k miles at the most (160,000 km).

Also could be the IACV (Idle Air Control Valve) is fouled and needs to be cleaned. It's a common problem. I can steer you to DIY threads to clean it after knowing which motor you've got.

Also could be air/vacuum leaks in the intake tract downstream from the MAP/MAF sensor.
