I convinced the owner of this 1985 Oldsmobile 98 “Time Machine” to leave it at PHAD for a few days for proper diagnostics and guaranteed repairs.
There a few things to take care of before proceeding with test driving and diagnosing the LOW POWER under load, and the excessively FAST IDLE speed:
-Left Headlight is out
-Left Front Brake is DRAGGING
-Power Antenna and Front Power Outlet don’t work…
-Drive Belts are LOOSE and flopping around!
Once we make the car more road-worthy, let’s focus on the main customer complaints.
Should be a fun and CUSHY ride!

you know you are a PHAD fan when you can date videos by the progress of Ivans thumb nail healing…..
Ivan the odometer could have flipped over 100000 so it could be 105000. The odometer back than dodnt have it so you could see after 99999
Is there a kit you can get to convert the AC system to R134a
Yea Ivan but does it taste like Poop? I had a olds 88 back in 1971 when I got out of the Army do not remember the year though. I would drive to Santa Cruz buy way of Pacheco Pass, I lived in Madera and Santa Cruz of and on. Back then you could live by the board walk in the winter pretty cheap Santa Cruz was mostly a summer resort then. I worked at Cup-of-soap from Lipton, it was a good job graveyard clean-up crew, that was a good time back then. I lived in several places for several years, but time moves on.
I can recommend to buy a stand-alone AFR sensor with display, and then make yourself a "tailpipe sniffer" that you can attach to the exhaust.
This allows you to measure the actual equivalence ratio even while driving, and it's not all that expensive. Most displays even have a 0-5v output that you can connect to the scope.
Sorry Ivan, attention to detail was not a thing with 1980s cars. They were summarily awful. Low power for the displacement, poor fit and finish, difficult to repair.
There is a fuel filter under the car near the back of the right rocker panel
When I worked at the dealer in 89, it wasn't unusual to get two bad ECM's in a row over the part's counter. I was real glad to find Toyota to work at in 92.
Amazing how much corrosion is on that vehicle for only 5K miles. (I know it 30+ years old!) Was it stored in a damp wet garage? I had an 1985 Buick Park Ave, (same vehicle, Buick branded) and I loved it. Slow but very luxurious and great sound system. I fixed my power antenna twice as the nylon cable inside would crack and break off. Back when you could take things apart! I think one of the weak points was the Mass-Air flow and Alternator. I went through 3 alternators on that vehicle.
This car is museum grade. Don't daily use it ❤
For all the drawbacks of the seals beam headlights, it was nice to be able to get them at supermarkets, gas stations etc and not have to go to an auto store. Back in 1985, the local supermarket had brake pads, belts, alternators, starters, ignition boxes etc.
35:00 what does Kieth say
The orange hub cap retainer was to prevent your hubcap from being stolen back in the day now they just steal the whole car
leaking fuel pressure regulator dumping fuel. classic back in the day
Nice Old Olds. Wow takes me back to my Senior year in High School. Thanks Ivan
In the early 80's I worked in a tire shop. They had some really weird stuff back then, just look at the Cadillac wheels and special wheel weights.
Put a 3.3omh resistor in the map sensor
Oh boy, I worked on SO MANY of these back in the day! Hot tip – watch out for the timing chain. Nylon gears that like to snap off or wear all the way down. Won't hurt the engine unless you are pedal to the carpet when it lets go, but still a pain in the ass to change out. The other nifty tidbit I can share regards that MAF. We changed SO many of these….if the engine popped back thru the intake ONCE, it'd blow that MAF pretty much right away. Did you notice on your '86 data that the MAT was reporting -40F? That sensor should be part of the MAF as well as the BARO sensor, if my recollection serves.
Also, your vacuum modulator might have a small rip in it – this could cause the odd transmission smoking like you found with the smoke machine. I realize it only has 5000 miles, but them diaphragms get old and rip at the drop of a hat creating a terrible vacuum leak, and if it's really shot, you'll get yourself an oil burner.
Alas…..my favorite feature of that car seems to be non-functional. That would be the multi-tone seat belt chime that only seemed to come on these Oldsmobiles. Much like the transmission solenoid bounce of a Chrysler Ultradrive, I could tell when one of these was behind me at the shop as soon as someone turned the key.
I can't wait to get a pico scope. They are way beyond the money I can afford. I bought a hantek just to get me started. It wont be very functional when it comes to injectors being I won't be able to see details like the pintle hump or ignition coil data. I've seen other channels use the Pico like none other to check to see if there is proper burn going on in a cylinder, cylinder turbulence from a leaky valve to looking at the pintle hump on an injector to see if it's actually working or not. All from a pico scope without even tearing into an engine. I've learned so much advanced tech, I can't wait to get out there and do what I love doing.
What about the regulator
It’s a pleasure watching you work on older cars while discerning OBD 1 information using experience and common sense..
