2004 SVT 2.3 Power Loss

I'm an old man also, but there is no such thing as a ZXT either. Is it a hatchback? a 4 door? Then its a ZX5, a 3 door hatch? Then its a ZX3. Okay, like I said, my car did the same thing, and all I did was switch the 2 solenoids on top of the black intake manifold. Have you tried that? I wouldnt trust the mechanic that claims he put 2 new ones on there. Please give it a try, only takes 2 minutes, tops.

Also as stated, one or more of the six valve body solenoids in the transmission may be mal-functioning. I would also run it by a auto parts store and run a code scan on it, even though there is no check engine light, it may come up with a code. Another quick check of codes is with the odometer, let me know if you want help figuring out how to use the odometer as a information tool.

How embarrassing...I can't even remember what model car I have long enough to walk from the parking garage back to my office It's a ZTS...definitely a ZTS. A sage green 2004 4 door sedan with the 2.3 PZEV engine. The only thing I have tried is disconnecting the two vacuum hoses going to the two solonoids on the intake manifold to see what affect it had on the engine when it was idling. I will try swapping them tonight when I get home from work and see if it makes a difference.

As for checking codes using the odometer, I would like to know how it works but I do not have a decoder, do you need one to do it?

Oh and my mechanic didn't say he put 2 new solonoids on the intake, he said he replaced the vacuum lines going to them because one was broken so he replaced both hoses.

As for the transmission valve body solonoids, I assume they don't throw codes if they malfunction?

[GreySkorpion]

Transmission solenoids are tricky, I have heard of them throwing codes and not throwing codes.

codes can be found here, and at the top of almost every sub-forum (you are in General Technical chat ) there is a list of informative articles, here is the link to dtc's: http://www.focusfanatics.com/forum/showthread.php?t=174739
