Delayed Throttle Response

[GerryO]

Did my PCV valves with the plenum off. Suspect your EGR tubes are clogged and the EGR valve is a bear to replace (even with the plenum off).

I'm curious as to whether or not a later model plenum (with PCV valves on top) would fit and earlier model engine with some simple modifications.

You might take a chance that some of these Nissan part numbers are the same (and less expensive).



The O2 sensors were a bear and I did the driver's side first thinking it would be more difficult. The reducer bushing on the passenger's side came out with the old O2 sensor and the threads of the old sensor were galled. I used a big open end wrench on mine, as I don't like using adjustable wrenches except only as a last resort.
