95 Mustang Gt Rough Running?

I Recently Bought A 95' Mustang Gt With The 5.0 Ho Engine And Heres My Problem It Runs Rough At About 1000 And 3000 Rpm Wether Accellarating Or Decellarating Thought It Might Be My Intake Air Controller I Removed That Cleaned And Reinstalled It Problem Still Persist But It Only Does It When It Is Cold Outside Below 35 Degrees Usaully On A Warm Day It Runs Fine Ive Also Changed The Plugs Wires Any Suggestions?

injectors maybe? try running some lucas fuel and injecter treatment... start small before spending the big bucks...

yeah i thought it may be something like that too. but ive ran injector lucas injector cleaner and also a higher octane fuel but the problem still persist and i cant understand why if it was the injectors it would only happen when it was cold?

well to be honest with you my 94 gt did the exact same thing and i could never pin point the problem so i just went and converted mine to carburated! and when i did that you have to put an out of tank fuel pump in to run the carburater and when transferring it i found out my fuel pump when bad! i don't why i didn't think about that when diagnosing my car but mine did the same thing as yours and all it was was my fuel pump! p.s. carburated made my car about 1/2 sec. faster on the 1/4 mile running a 650 edelbrock at 7 psi! it was totally worth it for the money! consider it maybe!!!

How much trouble was it to make the switch to a carb?.

did you clean the IAC?
