1994 Volvo 850 Sedan Non-Turbo Automatic.
Ok. The car has been running pretty good to up to 4-5 months ago. Not sure if this is part of the Symptoms of a failing timing belt.

First off, I would go for a long ride, 30-45 minutes, shut off the car for less then 5 minutes, hop back in it and start it up and I would get horrible hesitation on the acceleration. Very rough acceleration. So what i would do, is throw it in nuetral while I was driving, floor is a few times and it would go away. This would happen once in a while. Until recently where it started happening ever other time I was starting and stopping the car.

Ok now starting the car the next day would be fine first thing. Now while the car was shifting from 1st to 2nd, i would get a kind of winding spinning squealing sound. Then same thing would happen when it would shift gears until it got into drive. It definetly isnt any kind of fanbelt or power steering or alternator belt, etc.

Ok, finally, out of the blue, the car just stalled out on me on the parkway the other day out of nowhere. I pulled over, crossed my fingers, and it started again. So me being the crazy person i am, I decided to keep driving it the day after. Same thing happened when i was 5 miles from my house. This has happened at least 5 times within the last 3 week (this week the car has been in front of the house not running).

Ok, so i started to read on the boards. I changed the plugs, nothing. Changed the ignition switch, nothing. So I figured i try my crack at the Cam Position Sensor, by not replacing it, but trying to give it a temp fix by unplugging and plugging it back in like 10 times. Then i gave it one wack with a hammer lightly.

Then i tried starting the car back up, it started. Now, the car runs like crap. Seems to run fine in idle, but the second I touch the gas pedal, I get hesitation on the acceleration.. I tried driving it, same thing. The problem wont go away. Now the question is, can it be the timing belt? I read all the codes,

Here they are
A1 Codes
1-1-4 Program selector open circuit or short circuit to supply
1-4-3 Kickdown switch faulty or short to ground
2-2-2 S2 solenoid open circuit
2-2-3 Throttle position (TPS) sensor signal too low
3-1-3 Faulty signal from gear position sensor (PNP)

A3 Codes
1-4-1 Faulty pedal sensor, shorted to ground or supply
1-4-2 Faulty brake pedal switch, open or short
1-4-4 Brake discs overheated
2-1-1 Left front wheel sensor, not signal on moving off
2-1-2 Right front wheel sensor, no signal on moving off
2-1-3 Left rear wheel sensor, no signal on moving off
2-1-4 Right rear wheel sensor, no signal on moving off

A6
3-1-4 Camshaft Position sensor (CMP) signal missing or faulty

A7
1-2-2 ?????
1-3-2 ?????

B1
1-3-5 ?????
2-3-1 ?????
4-1-1 ?????
4-1-7 ?????

I did the little fix on the CMP, cleared the code for A6, and it didnt come back.

Also, I pulled out the fuel injectors out of the manifold, then I pulled them out of the metal that hold then from the top. Just to check if all the seals and gaskets were good. Just a little question, what is that air pressure valve on the side of that metal brackets that hold in the fuel injectors? Does it need air after you pull the fuel injectors out? I have no clue.

I mean i am mechanically inclined, and I have done plenty of work on cars before (even changed the PNP switch by myself), but I guess i was ripping things off for no reason. I was wondering if i messed up the air pressure on the fuel injectors, or it could be something else major like the timing belt.

Any answers would be so glady apprecaited, you have no idea. I live in Nassau County Long Island New York, and the car can probably make it to a place to get fixed of needed, but I was interested in fixing it myself and saving a bundle of money by ordering the parts online. If there is a reputable Volvo repair person in my area, please let me know. I would like to fix it by myself, but I sure as hell wouldnt mind have a down-to-earth repair person to let me know what i need to get this repaired. Also, the a/c inst working, and i just got it fixed last year with a new compressor.

Thanks again everyone, Carl.
