Ok so when i start my car she runs idle up real high about 2k then falls around 800 but idle jumps and she stutters. She feels like she is gonna die but doesn't. After i give her some gas and let her run for a little while she'll stop doing it. But when she is stuttering and i try to gas her throttle response sucks. it feels like if i give it gas it takes a couple seconds for it to respond. once idle is settled she has no problem and throttle respose is normal again. I thought maybe i had a vaccum/boost leak some where bud didn't find any. Ideas???
