Just spoke to the shop and they said they hadnt diagnosed the problem yet - they've had the car since Monday AM - and they're more than eager to pull the ECU and ship it to their specialist up north at this point - thanks to all!

Aah - got it - so let the shop pull the ECU and send it to the shop they use in No. CA who's been doing all their ECU work for past 15 years? Is this the generally preferred method of solving this issue? I cant picture many amateur Lexus owners/tinkerers ordering caps and dusting off their old Weller soldering gun...thanks!

the thread also correctly identifies the right capacitors that need to be purchased for a proper fix. most "specialists" are not keen to knowing this information (unless given to them).
just to justify the thread, yamae who is quoted many times is a very knowledgeable fellow who resides in japan and has worked with our ECUs before. he is the main contributor to the thread so credit goes to him and lscowboyls!
and you only need to read the first post, not all 800 in the thread

It would be wise to replace those ECU capacitors as one of preventive measures but judging from the situation, skipped teeth may be causing the problem, I worry.
Those ECU capacitors do not kill the ECU suddenly. As the ESR increases, the bypassing capability becomes weaker little by little and the performance of the ECU becomes poorer and poorer causing misjudgements of the processor and most people do not notice it when just started. Several months or more than 1 year later, they finally notice the problem.
Some people often surprise changing capacitors as a preventive measure that the car runs far better than before like a new.

The shop couldn't read any codes on their laptop and scanner probably because the 93 model doesn't have OBDII diagnostics, all you need is a bent paperclip and be able to count flashes.
I'd like to know how they managed to plug it in!

Right - its not throwing any codes - I may not know what theyre doing but they do - kinda - they know its not OBDII - theyve been in business with the same manager and owner for 30 years - they may stink but at least theyre experienced at it - theyve tried everything to get the codes but not getting anywhere - I just told them to send the computer the their standby subcontractor in No Cal - has a one day turnaround

I get that some people can do it - I probably could if I practiced r n ring caps on old circuit boards for an hour or two - but the shop has the car because they did the timing bellt and starter end of March so there it is - thanks!

So they sent my ECU to a shop that went out of business - Python in Stanton - I tried calling them but none of their numbers worked and yesterday the ECU came back to the shop that sent it out - so now they sent the thing to ecmtogo.com - a company in ft lauderdale that has an F- rating w/BBB and a bunch of scam complaints - they want $500 + shipping - they are accused of getting ECUs from junkyards and shipping them as found to fill orders for their services paid with PayPal online - I told them to only re-cap the board before doing anything else - Im not happy.
