Idk if this is the right place or not... i have an 89 firebird formula 305 tbi. I put a 91 350 in it from a yukon. Just dropped it in and it runs. It is very sluggish though. It also has a rough idle. If i tune the idle with the dist it idles nice but stalls when you put it into gear. Im at a loss with it... being that i used a complete 350 motor/intake/injectors do i need to use the yukon ecm? I do have it. Thanks!

 

I would look into trying the Yukon ECM-i think it is similar to what the TBI cars used and would suit the engine.For much more action,by those more familiar 350s in TBI cars,post in the TBI section
