Hello everyone,

I really appreciate this board and all of the help I have received with my engine swap on my new to me, one owner '89 240 GL. Well, I finally got it all back to together, and it started right up. But, its running rough under load with low power. It idles roughly at a constant 800 rpm but does seem to smooth out somewhat at higher rpms with but with little power. Temperature falls right in the normal range. A little background info: engine is suppose to have 79,000 miles, compression test shows 170 psi. on all 4 cylinders, both fuel pumps are running (but I have not actually checked the pressure), have replaced the plugs,(not the wires) cap, rotor, crank position sensor, air intake bellows between AMM and throttle body, air cleaner element, checked for any vacume leaks, and cleaned and seviced the throttle body, PCV system, and idle control valve. Initially the engine light was not on but after about a hour of driving it came on and remains on. Checked for stored diagnostic codes and very clearly came up with the following per the Haynes manual: 1-1-3 Fault in fuel injectors, 2-3-1 Fuel system compensating for rich or lean mixture at cruise, 3-1-1 Vehicle speed signal missing(What does this last one mean and what generates the vehicle speed signal?) As this was an junk yard engine that sat for an unknown time in the '90 240 it came out of, combined with what I have tried to describe does it look like I have some injector problems? Is it currently running in the limp-mode I have heard many of you talk about? I still have the old engine which was ran out of oil at 140k by the previous and original owner last spring so have considered swapping part or all of the fuel rail and injectors off of that engine. Any suggestions about how to proceed will be greatly appreciated. Thanks, Danny
