i have a lem g1, the tag on the outside says subaru d42v4 280404. i installed this engine and computer used into my sand rail and ran it last winter, worked great! this summer i moved to oregon and it did not get used until i tried to use it last weekend, the engine has always started very easy, now it is hard starting. once running it was only running on 3 cylinders, we checked for spark at coil, had it, put new plugs in, now it was running on all 4. went to run it and when we hit 4000 rpm it acted like it hit the rev limit, just shut down, then it would take off again. at one time it was only hitting on 2 cylinders, started back to all 4 and sounded great. when sitting in one place, not moving it does not shut it down, only when moving under load. any ideas?
