Right I'm back at last & before i finish reading your reply can I just apologise for using more Brit-isms here, NOS meaning to me "New Old Stock" as in an unused boxed item that's sat on a dealers shelf from back when these cars were current (Airflow Meter was replaced with secondhand and then New Old Stock item) and not the block-splitting, head cracking, rod-spewing goodness that is
!!!
Anyway, sorry for that indiscretion. I'm off to read the rest of your reply now... There's no "blush" smiley that I can see or I'd use that...
EDIT-: OK firstly I really should check the fault codes once I find the thread on how to do that again (saw it the other day but forgot what pins) and I will do once I've got the car home. I should also sort out my profile & fill you in a bit on my background.
I'm not another of the doubtless many clueless kids out there who see a big black Supra & think "there's MY penis extension sorted!", I've been into cars and bikes all of my 28 years on Gods earth & the Supra will be car number 30-odd that I've owned/worked on. I have a fair amount of experience working on more complicated motors, having owned a couple of BMW 7 series & Jaguar XJ6's previously too & I'm just a noob to Toyotas as opposed to a complete vehicular noob.
Also, the Supra I'm looking at is from a guy I know who runs an engine rebuilding business & has had a full engine rebuild done by him (head skimmed, valves ground & shimmed, rebore, new cams/pistons/rings/bearings/seals/water pump, exchanged re-con turbo, the whole nine-yards basically).
The story is that he did this work about 4 years ago & the owner promptly paid up & then vanished, since it's been stored so long on his site he's now taken ownership (storage charges being more than the car will ever be worth) & has the paperwork in his name. As there's still a running fault i.e. the idle problem I described, he just wanted rid & I wanted rid of my old Mitsubishi Pajero too so we did a swap.
Aside from the idle fault which from reading threads on here I believe could well be as simple as setting up the TPS & re-adjusting the timing, as well as removing the dump valve in favour of the recirc. & finding any missing vacuum pipes, there's nothing wrong that I can find mechanically/electrically or even corrosion. Plus it has a nice set of 18" alloys & new tyres worth more than the Pajero on their own!
Anyway I'm gonna stop rambling now, suffice to say you don't need to worry about me baing carried away with the emotion of the situation (which I certainly am!), because I've evaluated the deal & I'm definitely coming away with the better end of it no matter what happens...
