2003 ctt low power at low rpms


Recommended Posts

I just replaced all 8 coils and spark plugs.  Also replaced both valve cover gaskets, spark plug gaskets and cam adjuster seals.  Now my Cayenne Turbo is very sluggish up to 3000 rpm but above 3000 it runs like a raped ape. Motor runs smooth.  When first started it had code P0016 which I cleared and hasnt came back in over 200 miles.  Any help would be appreciated.  

 

Thanks

Could be a air leak with the gaskets you changed. More notable at rpm' s before turbo charger is kicking in. I have something similar and it occurred after my  service guy did the same work like you did now

Would you recommend trying to tighten them more or remove check the gasket?

All bolts were tight both sides but I did find where the crankcase breather check valve connects to the air/oil separator what not completely pushed on. I made sure that connection was good and test drove again with same results.

P0016 is bank 1 camshaft sensor reading is different to the crankshaft sensor. 

You need to check the camshaft sensor pickup tabs are not bent! They can be bent when you lift off the bank 1 valve cover. Just a small movement will weaken the inductive pickup signal and lower rpm the sensor voltage is not good. 

Aside from this all obvious things like the gaskets not seated properly, pcv pipes leaking and coils seated on plugs tightly and plugs gaps correct and torqued down correctly?

Great!!! Lewis you remember what i said?!

the bad running started after they changed my valve cover and spark plug gasket. Maybe here is a hidden reason for the trouble 

Thomas definitely worth a check to see if related to your issues.

 

Cobra23 glad you found and fixed it, bet that feels good!

Wondering how this can happen during taking off the valve cover?!

Pretty easily, when you lift off the valve cover the back edge catches on the metal tab of the camshaft pick up and it's then bent. 

 

Luckily before I removed my bank 1 valve cover I read the Pelican diy guide and made sure I didn't catch mine when lifting it off and back on. 

 

And who said the internet is full of bad info? Lol
