I just finally cranked and moved the car after nearly a year of doing my GTE swap and some mods, and I have a few minor drive ability issues. The most major of which is the surge at just off idle. When I crack the throttle maybe 5-10% to bring the rpms up to around 1500 to take off from lights and stops, it will surge between 1k and 1,500 RPM. Any idea of a cause? It is really a nuisance as I have to rev it up to around 2k to take off so as not to get caught in a stumble and have the car stall at take off. Any help would be appreciated, thanks guys.
