hi all well i have a 94 mustang gt and i took the upperintake off to replace some vacuum hoses cleaned the tb , aic , egr and replaced gaskets then put all back together at idle she runs fine i can rev it up and it sounds great but when i go to drive it it spitters and sputters almost as if a plug fouled i checked all plugs and wires ect i am stumped any ideas out there any advise would be better than no advise thank you it ran fine before i took it all apart
did you replace your intake manifold gasket? Might also try spraying starter fluid around the lines/intake to see if maybe one of the vac lines cracked or split while you were doing this.
i checked all vaccum hoses and sprayed carb and choke cleaner on all the hoses everything seems fine and its still do it could it be a cracked upper intake i see no visable cracks at all could it be on the inside
