Hey so the other day I went out driving and all was fine, on the way home I got on it kinda hard and it kinda felt like the power just cut out for a second, when I came to a stop light the car died. I started it up and it died right away, started it up and as it was dying i pressed the gas but it seem like rpms were barely getting up so i floored it while in neutral waiting at the light to get the car to stay running. Once the rpms got up i let off and had to keep the pedal pressed a little bit to keep it running. I got it home ok and left it. I also noticed that after that power cut feeling the sound from the exhaust was quite different, more raspy and sounded dryer if that makes sense.

Today I changed out the spark plugs thinking maybe i fouled out one of my plugs, gave it an oil change while i was down there and when it started up it was ok, still sounded different but it ran just fine at idle. I let it warm up most the way and took it around the block, by the time i got back home it was at full temperature and I was experiencing the same problems, it would die if i let off the gas and to keep it running i have to keep my pedal down slightly.

Any help, advice would be awesome...

check if the map sensors vacuum line is connected

I appreciate the suggestion. I did check the line, and it is secured tightly from the sensor all the way to the uim. I did have a friend help me convert from sequential to non-sequential so most of the vacuum lines are gone.

The thing that boggles my mind is why when its cold it idles fine and doesnt die, but when its fully warmed up it dies soon as you let off on the gas.

I checked all the vacuum lines over again, seems that everything is connected. Running out of ideas.

Cold idles fine, warmed up dies ...
