Any Volvo guys here? 93 850 question inside
« on: January 20, 2010, 11:12:00 AM »

I an working on a 93 Volvo 850. It idles great for a while and then the idle drops, then jumps to 1500 and then settles down for a little bit, repeat.

I am trying to find the data connector so I can watch the data stream but I'm not having any luck. All data isn't helping either, just sending me in the wrong direction.

Unplug the MAF sensor and see if it runs any better.  Volvo's eat em like candy. I think the DLC is in the center console behind a trim panel.

I have tried unplugging the TPS and the idle control valve. It ran a lot better with the TPS unplugged, but it did the same thing. It's warming up with the MAF unplugged right now. I will report back

No clue.  The '91 era 2/7 series still had the LOLOLOLOLOL diagnostic console underhood.  You were given a bullet connector and a couple receptacles to plug it into depending on what you wanted to do, one of them would flash codes via a LED.  It looks kinda similar in size and shape (of the flip up cover) to the underhood diagnostic ports on Toyotas.

I just found out a year ago someone soaked the TB and the problem went away for a year. I can't imagine there is anything in there that would cause this. The iacv is completely seperate from the TB and IM. I also ruled that out with a piece of hose in place of the iacv. The problem it still there even with it fully bypassed.

early 90's mazdas had the port under the hood too.  It was fucking wierd when I first saw it.

Their's is like the Toyota DLC port.  Pretty standard, really.

What Volvo does with the actual self-diagnostic terminal being underhood is fucking weird.

i did find a port under the hood where you could use jumper wires or something to flash codes, but that wouldnt show me what i wanted. i wanted to watch the datastream with the scanner.

kinda pointless now though, the guy got deployed today and picked the car up late last night so i wont see it again for quite a while if i am still working for that shop by then. i think this is temporary. im not excited about working on shit like this for a living

There's no datastream that I know of for pre-OBD2 Volvo, suck it up, and if you aren't excited about working for a living then perhaps you would like to consider relocating to an already completely socialist country?

I have no problem working for a living, I just want to find something that doesn't involve getting shoulder deep in dirty piles of shit everyday. Hoping to go back to my cleaner job of composite work. It's dusty, but not greasy.

I work on brand new-ish Porsches everyday.  I still get dirty/greasy.  If you want to stay clean, dont work on cars.

I intend to get out of it as soon as is financially possible.  I see older guys doing this kind of work with all the stress and I dont want that to be me. Im more than capable since im still young, but I def. dont want to be doing this when im 40.
