My car has been running great for the last couple months. Took it on a roadtrip from seattle to phoenix and it still runs well. Today I went for a cruise and took off from a stop light and all of a sudden I had no power response in my pedal....Then it kicked back it and started to lurch back and forth. After about 3 to 5 seconds it was gone.

Down the road I stepped on the gas again and it started to lightly jerk as if fuel was being cut off and turned on rapidly. I happened to notice it started around 2700 rpm.

Its a turbo swapped 89. Everything is pretty stock except for the light mods in my sig. Any help would be appreciated
