Default Less power after warmed up

I have an 04 ctt that has noticeably less power once it is up to normal operating temperature. Any ideas?

See if you can pull any codes, but a temperature sensor, or something that basically says your engine is cold when it is warm, can affect performance, as fuel mapping will be wrong.

Hello, I have issues with my gearbox on Cayenne S 2004. When I start it up cold, it always starts at first gear, nothing wrong here, but when I accelerate and it turns to second gear, it does it with a twitch, not softly. What's wrong? Gearbox about to give up? When switching gears from 2-6 nothing is wrong.

I guess I'm going with the eps center support fix. It seems to be a good solution for that problem.

1st to 2nd when cold is always a bit abrupt. I think it's normal.

Yes. Mine too.

There also seems to be a "second" shift (torque converter lockup?) into each gear, far more noticeable when cold.

I also tend to drive slowly and gently for the first couple of blocks. I will manually shift at lower RPMs.

Anybody know if those codes could be related to my problem?

When is the last time you did your plugs? The difference between cold engine and warm engine for my 04 was pretty dramatic. I dealt with it for quite a while until I did a major service interval and replaced all plugs and coils. Torque arm was done at that point too, as well as some of the fluids. Problem went away and it kept its power after warming up from that point on.

I did recently replace coil packs and plugs. I tried e3 plugs. Do you think these plugs are ok? Coil packs are Beru.

I do not know much about which plugs are good vs bad. I can tell you I used Beru coils from ECS, as well as NGK plugs.
