If this car were newer then yes, I believe that using a scan tool with live data could help diagnose a bad MAF. Unfortunately, my car is pre-OBDII so all I get is a blinking light to read data from the computer.

Update! Good news too :D Car parts came in today, so I was able to get my new Volvo branded coolant temp sensor installed. Pulling out the old one it also was Volvo branded. Topped off the coolant, fired her up, and same dying issue. So even though this didn't fix my problem I feel better knowing th...

Just for clarification the cap and rotor are Bosch, plugs are Volvo. I learned the hard way that aftermarket parts for these cars are horrible. It's best to get the good stuff.

Whoops, also noticed I had left the linked Youtube video as private. It's now public and open for viewing. Skip to about the 8min mark for the rough idle.

After letting the car run for 15mins I pulled spark plug #1 to take a look. It had a little fuel on the electrodes but not so much to lead me to believe it's running incredibly rich. In 2013 it did have a running rich problem that ended up destroying the catalytic converter. After replacing the cat,...

Thanks for replying all, Only other codes are a few random ones from A7 (Trip Computer) and A3 (ABS). No codes from A2 (Fuel System) or A6 (Ignition). The cooling fan only kicks on when the engine comes to temperature. I have to hold the throttle open and rev the engine at 1500 rpm but when the temp...

1993 850 N/A Automatic Transmission 250k miles https://youtu.be/0hOZ8l98tCY Hey guys, it's been a while since I've been on the forum but I've run into an issue I cannot figure out so I come here for guidance. I'm trying to get my old 850 back into driving shape. The car has mostly sat for the last 1...

Does the fan speed selector switch "feel" any different when you slide it? I had an issue very similar to this just a few months ago and it came down to a problem in the contacts inside the switch. The switch felt much harder to slide and just didn't feel normal. When I cracked open the sw...

From what I've read the 1993 is the red-headed step child of the 850s so I'm not surprised this is different as well.

I tried getting anything to come loose again to no avail. I'll devote some more time to it this weekend and if I get it out I'll post some more pics of how things work.

Thanks

Hi all - I've been reading these forums for a few years now and it's been a tremendous help allowing me to do most of my own repairs. I'm to the point now where the major stuff has been fixed and I'm working on the minor things....like the spoiler light bulb. I thought it would be a simple task, but...
