JDM spec (550mm compared to UK 500mm) wiper blade assy with proper 'wing' at the driver side and matching longer pair at the passenger one.
Engine bay is pretty much done.
Too hot to carry out detailing so I'll do that once it's cold enough
Going to return the old AUX belts, wipers and wheel lock nut to the owner.
Time for the test driving session.
As the temperature was warmer than the last few days, adjusted the tyre pressure to OEM 40/33psi spec as it will drop slightly when it gets colder.
Unwrapping the car in preparation for the test driving session.
I washed the car before start of the service and then wrapped it so still very clean.
As always, it takes several trials aligning the engine bay cover to minimise the fogging up of the rear hatch glass.
This NSX is coupe model so not too bad but still, with the old tired rubber seals, not easy task.
With Targa model, it takes ages as the engine cover is much heavier than the coupe one resulting in so tired rubber seals allowing vaporised moisture to enter the area above the cover.
Initial test driving session finished with no issues.
Back on the lift for the check up.
No issues and time for the base idle rpm check.
If your engine is healthy and at the right timing as well as clean TH body, you should be able to run the engine at about 600rpm no problem. If it's dirty or not healthy, you will see fluctuating rpm in the order of several 100rpm going up and down or even stall the engine.
Followed by the IG timing check. Again, if it's done properly, you should see spot on at the red marking on the crank pulley.
Removed SCS terminal, tap on the TH pedal briefly and now the idle rpm back to normal 800rpm.
Reset the ECU and run the engine for about 15min to re-learn all coefficient parameters for the closed loop EFI control.
Locked the idle air screw with the liquid gasket.
Ran out of the time for the 30min of 65mph cruising steady speed mode testing for the feedback control of the new O2 sensor. Will do it together with engaging VTEC over this weekend although the weather forecast is not great for Saturday and I don't want to drive the car in wet condition before replacing the tail light assy gasket so probably do it on Sunday.
Nearly at the end of the service.
