I have a four stroke 115 that idles great but when you go to accelerate it stalls. If you can slowly play with it and get it past that spot it runs fine at high rpms (just getting it to that point is the issue.) The fuel injection system has been cleaned, new spark plugs have been installed and new fuel filters. It happens so quick that it is pretty hard to diagnose so i was wondering if it could possibly be a sensor or something of that sort. Any input would be helpful. Thanks!
