Engine Stumble
 
I drive an 02 SVT. At idle my car stumbles or skips a beat sometimes, and when taking off in first it stumbles a little. I hooked up my diablo scanner and read some data. At idle Fuel rail pressure is 39, fuel pressure is 30 I believe, STFT fluctuates between -1% to 2%. Does anyone have an idea what could be the problem? Certain data I should look at? Any help would be appreciated.

No information listed for modifications. STFT is only close because adaptive should be turned on, thus utilizing LTFTs... is the vehicle actually tuned?
