Just recently purchased a 91 240sx, with an S13 Sr20 swap, the swap itself is VERY clean, the car runs great with the exception of having atmospheric blow-off and trying to die due to that and sometimes, it wont start, like not getting tach signal ,so i can get out, unplug the cam angle sensor, i hear what sounds like the injectors re priming (a whine). Then it'll fire up and run. But dunno if its the atmospheric or what that makes it laggy and studdery during the beginning of boost or not. Any takes on this?
