Today I took off both the upper and lower intake manifold, along with the throttle body. I replaced the throttle body sensor ERROR P-1128 or something and a knock sensor which is mounted under the intake manifold gave an ERROR P-0345. Pain in the A. 1 1/4 hour. lexus quated 611.00 for the labor and knock sensor. I got the part for 163.00. I will post picks of the removal and installation later on this post. for both the knock sensor and throttle body sensor, and all parts needed.

If you can't drive the car over 2000 rpm because it chugs and stalls, and it runs hard over 4500rpm at the same time if you can get it past the lagging retarded timing from 2000-4000rpm you probably have a knock sensor error. More common with S/C set-ups because they go bad with extreme heat!

 

is this an issue because you have the RMM supercharger?

 

...remember to replace the manifold gaskets.

 

yes, and reinstall ALL of the bolts too........ eventhough you may have extra ones in the end.



just kidding or coarse you knew that.


PM me, curious how you like the RMM supercharger and why you choose it over SRT. It sound like you may have installed it yourself, as I plan to also. I've been looking into this mod as an option or maybe an SRT version.
