Having issues with my escape...
Hello everyone! I was preparing my sons 2004 escape (3.0L) for a vacation by changing out the spark plugs. When done, I noticed that the engine lacks power during acceleration and has a very high shifting point from normal (3500 rpm). There were no DTC's set so I took it all apart again, this time changing the intake manifold gaskets both upper and lower. I put it all back together and have the same issue. I have double checked (actually quadruple checked) all of the vacuum lines and electronic connections but to no avail. The truck still has very poor power, at idle it bottoms out around 500 rpm. From a start at a stop sign, with the pedal floored it takes a city block to get up to 35 mph. Any suggestions on where I can look next?
Thanks for your time!

I agree, just puzzling.. Cant find anything out of order. All hoses and electrical connections are intact...

An easy way of implementing and later diagnosing (if necessary) these kinds of things is to change one thing at a time and un-do the change if something bad comes about in an attempt to determine if the change caused the problem (which it usually does). Changing unrelated components is usually not the best thing to do, as most problems come about as a result of something having been changed... so, change it back (put the old spark plugs back)... one thing at a time...

search the internet for some pictures of the hose routing and verify that against yours.
Check your spark plug wiring for the correct firing order. Does not sound like your issue but I would be checking it.
Any chance you damaged the maf sensor? Look that over too.

Switching the wires is pretty easy on the cylinder facing the front of the engine. The center and the one on the drivers side are easy to get messed up. But I think I got an check engine light when that happened.
