I've got enough technical know how and actual mechanic friends that i COULD do the repairs. At this point, my only other vehicle is a 93 F-150 standard cab. Family of 5 isn't working in that situation. I'm gonna try to get the vehicle back home (I have 2.5 acres of storage :-P ). If I can tear down ...

I bought the car used with 168K on it. Its been spot on reliable. I add 100 miles a day doing normal 5 day workshifts. That'd doesn't include the in and around mileage. This isn't an ongoing problem but something that occured 2 weeks ago I have been trying to fix. I took what I knew already about au...

Well, something I know I checked was the Mass Airflow Sensor, but dealer said they plugged a new one in and its running fine. On the flip side of this, I have oil from the engine in my coolant now. Looks like my volvo ownership is coming to an end soon. Really liked the car but the repair is more th...

I had same problem. I can't tell you any numbers as I just replaced the rotors and pads on the front. Inspection and I would have thought nothing wrong with the rotors compared to some of the Fords and Chevy's I have owned in the past however.

More troubleshooting efforts...

I've manged to figure out a few more things about the problem. 1. fuel pressure is good. I get a good 45psi with key in pos 2 with engine off, and still with engine on. Under pressure, it dips to about 38 but stabilizes again fairly quickly. 2. Fuel filter is clean. Easy blow through. 3. Throttle Po...

93 850 GTL Fuel Pressure

Ok, after much work going into trying to fix this problem I posted earlier on this board, there is one thing I want to check and rule out for sure. Problem, I can't find the specs for my car. I have a 93 850GLT with 180K or so miles. What I need to know is the regulated and unregulated fuel pressure...

Strange Sound

I posted this in the original but I will elaborate a little more. When the car sits in idle, it will erratically go between 400 and 1000 with a spike every minute or so to 1500 and then back down to almost stall. Right after a peak, I hear a quick hissing sound. Its on the right side of the engine a...

MAF Sensor

I already did this during initial trouble shooting. After I pulled the MAF sensor on while running in idle it ran for a few seconds and died. It sounded like for a minute it tried to smooth out. Buddy came over and we did the same thing with me on the gas after he pulled. Revved fine but died still.

Codes pulled from 93 850

I finally figured out how to get the codes from my car. What I got was a 5-1-2. Makes sense as it SEEMS like a fuel problem but pump and filter all seem fine. Like mentioned before, thought this could be the TPS which I already replaced which oddly did make it run better than it did but still not dr...

93 850 Idle Surge and Stalling

My 93 850 GLT(trim level..Not sure about how to know this) just out of the blue started acting up. I'm not totally sure of the miles. When I bought it 5 months ago, it said 168K, and had receipts from prior month around that. I add about 2K a month as I drive 100miles a day (almost all interstate) t...
