i have a 99 eclipse gst im having a problem when i start the car is starts nice and revs up nice but when i put it in gear and hit the gas the car will studder and then as soon as the turbo goes to spool up the car drops the load and its sounds like its missing but if i slowly press down the gas it will go and speed up slowly but as soon as it gets to much it will start to miss again

I had a similar problem when i first bought my car. It was the fact that whoever had the car before me had cheap sparkplugs gapped wrong and they were old. Plugs are cheap, try a new set.

That could also be a huge boost leak. I just replaced my intercooler piping with hard one. One spot had a little space in it. When it hit boost it wanted to stall out, I had to keep it in a higher gear so no boost would hit really,. Was very hard to drive more than like 5 miles an hour. My car would shake and studder really bad with it had just a boost leak. So if you can't find what it is try doing a boost leak test. Also as dsm4me44 said, definitely first check your spark plugs and make sure they are gapped correctly. Might as well just get new ones. Also check your wires. An easy way is to at night spray a light mist of water on the spark plug wires and look for sparks.
