Intake manifold runner control valve
hey i have an 04 f150 lariat with a 5,4 in it and 220km on it, i replaced all the plugs about 8 months ago and had to replace various coils on separate occasions. There is a pretty bad misfire (bad enough to make my CEL blink) and when I plugged it in it said that cylinders 3 and 7 were misfiring which i assume is just coils but I also got the code P2006 indicating that my intake manifold runner control valve is stuck closed, I'm just wondering what the possible problems are that can cause this, do I simply replace the imrcv, if so is it an expensive part? can i just clean it? is it electronically controlled or vaccum controlled? I had used a hypertech programmer in the past but it is currently on stock settings and I replaced the intake manifold gasket once as well so I might of messed something up then, please help! any tips on how to inspect these parts would be great, pictures are always nice to have to
