[Supras] Auto Trans & Oxygen Sensor Questions

[Rockey Fox]

My Innovate LC1 wideband is installed in the stock location with one of the analog outputs programmed for narrow band which is connected to the ECU.

Group,

    Questions are for my '86 MA70 Supra (N/A) automatic (daily
driver).
    Does the valve body have to be removed to replace the #2 and
Lock-Up solenoids ?  Also, has anyone experienced and intermittent #2 &
Lock-Up solenoids ?  I'm asking because I don't want to spend the big
bucks (about $165 each) for these solenoids if the problem is something
else.  #2 solenoid passes the resistance test, but the Lock-Up solenoid
fails.
    If a wide band oxygen sensor is hooked up to the factory
computer (using the wide band connections), will everything work
correctly ?  Might be a waste, but wonder if it will work.  From what I
know/read, the N/A Supras have no full throttle enrichment.  So, except
when cold, the N/As run on the oxygen sensor all the time.  If anyone
knows differently, please let me know.

Thanks, Skip
'86 MA70

P.S.  What's the highest number of miles anyone has achieved with a 7M
powered Supra without rebuilding the engine (valve job OK) ??  I'm
trying to get 300K (hope, hope).
