Raise the rear wheels and see if they spin as freely forward, as
reverse.

Hi, its time for a ring set job in this vehicle. the blue smoke is a sign of major oil consumption due to bad piston rings. you also have faulty valve seals as well. this is deep engine repair and it will be costly.
If you cant do this job soon, be sure to watch the oil consumption by checking the level regularly and, monitor the oil pressure as well.

P1521 - VRIS Solenoid 1 I have replaced the VRIS (Variable resonance idle solenoid 1).
P0750 - Shift Solenoid A malfunction
There is more than one solenoid in the valve body and to make sure he is
replacing the right one. I will say that with an electrical malfunction
code---it's usually the wiring or the solenoid----so not a real bad
choice. Come to think of it I think there will be 4 solenoids---A,B,EPC
and TCC. So he needs to find out which one is the bad one before he goes
replacing.
Good luck
Testimonial: "Thanks for the prompt and concise answer. I suspect it might possibly even a short in the system due to abuse. At least I have a starting point now!"
The 1st thing that MUST be done is to have the electronic engine control system computer (called the "PCM") scanned for fault codes, this gives you the starting point for diagnosis od why the warning/fault light is on. You can get the scan for fault codes done for free at any Autozone or similar discount auto parts store in your area. Aamco Transmission does the scan for free as well.
