so i have a 94 mustang gt with a 5.0 in it . i pulled off the upper intake to change the vacuum hoses under it while i had it off i cleaned the tb , aic ,egr and changed all the gaskets then i put it all back together and it ran fine before this ...... when it is at idle it runs fine i can even sit in the driveway and rev it up and it sound good but when i go to drive it it starts to spit and sputter and backfire almost like a fouled plug would do ... i checked all vaccum hoses , mass airflo , sparkplugs and wires even pulled everything back apart 4 times even checked the upper intake for cracks thinkin i cracke it but nothin i really am out of options here any advise would be greatly appreciated thank you

check your connection of your air intake tube to your throttle body. even for holes or cuts even. when i had my last coupe this happened to me and it turned out to be the rubber sleeve connecting the throttle body and that air intake together

I would check plugs and wires

[mustang50lx]

Did you have the distributor out? Is it in time? Crossed plug wires?

what did you clean the parts with??

My guess would be not timed right.
