Problem

On the way to work this morning right before I got there I started to feel a throttle lag ? So I opened my hood saw one injector was leaking . After work I open my hood again gave a little push on that injector then started it up waited about 3-4 Minuts saw it wasn't leaking . Started to drive home felt the same lagging when giving throttle then my service engine light flashes for about 2 Minuts then went off and never came back on ? Still lagging in my throttle then I got back to the joys opend my hood and injector seemed like it was dry ? Any ideas ?

Wait until the car is cool and then turn the key to pressurize the fuel system. Look at the fuel rail and injectors to make sure there is no fuel leaking that could have evaporated on a warm engine. It is possible that the o-ring is worn or broken. There is a reason why the injector was out of place.

Maybe since the work was done it was seated properly and just worked its way out? But if its back in place you shouldnt be having the lag issue unless its still not right. Maybe a bad o ring?

Maybe there is a little pinch in the o ring causing a leak.

You can lubricate the O-rings with a little motor oil so that they will slide in easier.

Just double check all of the work that you did when you replaced the intake manifold. Make sure that all of the vacuum lines and electrical connectors are connected.
Also, if your Check Engine Light illuminated, there is likely a stored code that you can retrieve and get a better idea of what happened.

You can swap them out if they need to be replaced, but you should scan for codes to determine what that flashing CEL was all about.

Yeah I'm gonna have to do that cause I just got done driving it and it popped on again !! But it really feels like it's a spark plug problem ? How long does it take usually before you should change the spark plugs ?

Ford recommends replacing the factory platinum spark plugs at 100k miles.
A flashing CEL is usually caused by a misfire so you may be correct, and your problem could be ignition related. There is undoubtedly a stored code that will perhaps help narrow down the diagnosis process.

Yeah I'm only saying because the last time I felt this problem it was probly year and half ago and I changed the plugs and it felt great after .

Will a scanner tell you if a coil is burnt ? Also how much are coils usually ?

It will tell you what spark plug is bad, Then you can check if its the coil or the plug. Also its not too expensive if you just need one coil but if you buy all of them i think its like 170 on AM.
