Volvo :: 1996 850 Turbo Wagon Engine Knock?
I just got my 1996 volvo 850 turbo wagon running, after I replaced a valve, lapped all the valves and replaced all valve stem seals/full stage zero(timing belt, plugs, wires, cap, rotor, thermostat). Boy was she a strong runner, for the whole day it was running. I do admit to abusing it quite a bit. But what else would you expect from an 18 year old kid who just rebuilt his first volvo engine ? Now, i will note that the car had horrid previous owners, that took no care of the car(ran it low on oil and who knows what else). I know I ran it out of oil once, on the way home from buying it.....the guy did not put the oil filter on tight enough, and it blew the oil filter seal out. Luckily volvo's have low oil sensors. after i rebuilt the top end my engine was throwing out blue smoke for a while, but i thought it was just a bad turbo bearing.
Anyways, to cut to the chase; My engine sounds like this one. [URL]......
I did a compression check, all cylinders at 180 psi. all my lifters look good. I had a few plugged oil passages in the cam cover, but none that go to the lifters. i pushed on all valve springs, they look good. i used a screwdriver and hammer to check if the valve guides pulled out, and the valves are solid in place. I was still making boost even though the engine was knocking like this, so i know its not a rod bearing, because the knock sensors would have picked up on it and dropped the boost.
Volvo :: 1994 / 940 Non Turbo Wagon - Taillights Won't Come On When Lights Switch Is On
I have a 1994 Volvo 940 non turbo wagon. I just started having issues with the brakes lights and taillights not working. I have checked all the fuses visually and also did a continuity test on each one found all the fuses were good. I have replaced the all the relays, I have replaced the large red relay ( bulb failure relay ) and even did a continuity check on the bulb failure relay pins that are specifically for the rear brake light, everything checked out fine. I hesitate to change the brake light switch because the third brake light is working fine. I have considered replacing the headlight switch due to the taillights won't come on when the lights switch is on. My headlights do work though. There is no light on the dash indicating a bulb is out now since I replaced the third brake light bulb.

Volvo :: 1996 / 850 Turbo Wagon Died In The Middle Of Freeway Without Warning
My 1996 Volvo 850 Turbo Wagon died in the middle of the freeway last night without any warning...I was driving it home after purchasing it from a private seller who is completely ignoring me now (of course). The car ran fine on the test drive and fine for the 40 or 50 miles on the way back home and then suddenly stepping on the gas did nothing and I had to get off the road immediately. I'm 8 months pregnant so needless to say, I was extremely freaked out.
Anyways, I had it towed home. Today I went out and started it and it was a little bit hesitant but it started. The RPMs were bouncing around below 1000 and the car sounded like it wanted to stall but didn't.
I read online to start it and turn the AC on see what the RPMs do and that this can diagnose an idle control valve that needs replacing. I went out and started the car again, blasted the AC and now the RPMs were staying steady at 1000 and the car no longer sounded like it was about to stall. The RPMs did shoot up passed 2000 once shortly after turning the AC on. I'm assuming this must mean that the idle control valve needs to be replaced.
Someone else had posted about their car (same model/year as mine) would die unexpectedly and in their case it turned out to be the mass air flow sensor. I am really wondering about the fuel pump, fuel pump sensor / relay.

View 11 RepliesVolvo :: 1989 740 Turbo Wagon Won't Start - No Noise From Fuel Pump
I recently bought this car in its current no start condition after sitting 3 years. Initially I jumped it off and it just cranked, no attempt to start and no noise from either fuel pump.
I checked the fuses and the fuel pump relay behind/under the radio and it clicked and was dated 2006 so it had been replaced. I assumed it was replaced when the under car fuel pump was replaced at it was a replacement.
I sprayed a little starting fluid and it fired right up and ran until used up.
I ordered both pumps and strainer and installed the under car pump earlier this week. The in tank pump and strainer looked horrible and original. There was a small issue with the return line on the in tank fuel pump sending unit when I removed it that required brazing which I got back from the shop today.
This afternoon I installed the in tank pump & strainer on the sending unit and installed all that stuff. I spliced in a quick disconnect in the wiring harness for easy separation/installation next time.
Jumped the car again [yeah needs a battery] after everything was hooked back up and no in tank pump heard with key on to prime several times and no start although I hear the under car pump quit after attempting to start and they turned off.
Is there any other fuse/relay to check? If the under car fuel pump is evidently working, wouldn't it pull fuel without the in tank pump coming on? There's about 3 gallons in the tank. I'm going to test if there's current to the in tank pump tomorrow.
Volvo :: 1995 Turbo Wagon - Engine Holding High RPMs Between Shifts
I am new to my car. It is an '95 turbo wagon with a 5 speed conversion and a ARP orange ECU. The issue is the car is holding shift rpm for 4-5 seconds after I take my foot off the gas. Since I am taking the load off the motor when I clutch in, it actually climbs higher before it drops off. Needless to say it is not really drivable in traffic that way! The idle rpm is ok and the car pulls really well when accelerating. I have checked for vacuum leaks and I am heading for the Idle Air Control valve. I don't think the engine has any other mods and it is pretty high milage (188k).
View 1 RepliesVolvo :: 740 Turbo Wagon Cuts Out While Driving When Engine Reaches Its Normal Temperature
My 1989 740 Turbo wagon cuts out while I'm driving. It only ever does it at about the point when the engine first reaches its normal operating temperature. It can cut out while idling or when driving at normal speed. I'm not sure if it's related to temperature or time (it usually cuts out at about the 5-8 minute mark), or if this is simply coincidental. It does it nearly every day.
It's definitely caused by the fuel pump relay cutting out. I've replaced this already, with no improvement. Something is causing the relay to suddenly lose an input.
Once cut, it takes a few quick flicks of the key to the START position for the fuel pump relay to receive power again. It will then drive faultlessly for the rest of the day. Although, if allowed to sit and cool for many hours, it will sometimes do this again.
Volvo - 940 :: 1995 Turbo Stalls In Reverse / Hesitation On Takeoff
I have my 1995 Volvo 940 Turbo that stalls in reverse and hesitates on take off. The following is a breakdown of what has been done so far:
1. Initial Issue from March to October is hard starts; it would take 15 minutes or more to start car; it would be longer sometimes in cold weather.
2. Car would have erratic idle after startup; car reaches operating temperature before movement; car would bog down in idle and die only in reverse; initial acceleration from takeoff is slow;
car runs fine once out of first gear from takeoff; car bogs down on braking with idle lowering; sometimes car stalls at braking; gas is sometimes tapped slightly to stop stalling.
3. Issue of hard start would be intermittent; it would be less prominent in hot weather and more prominent in cold weather.
4. Sometimes in rain or wet weather, car would stall and sometimes backfire; Distributor Cap is normally changed.
5. By October, a no-start condition occurs.
6. Car starts now, idle is not erratic; car would bog down in idle and die only in reverse; you barely tap gas to keep from dying in reverse; initial acceleration from takeoff is slow; car
putts a little; car runs fine once out of first gear from takeoff; exhaust flows strongly; takeoff slightly improves incrementally with continued operation; car bogs down on braking with idle
lowering; sometimes car stalls at braking; gas is sometimes tapped slightly to stop stalling.
7. During idle or operation, sometimes coolant will boil in reservoir; toggle fan brings temp down to normal in between fan cycles; toggle fan keeps coolant temp normal in really hot weather.
The following parts have been changed and are still prominently new:
-Ignition Coil
-Spark Plug Wires
-Spark Plugs
-Distributor Cap (Initially Sealed With Sealant, Condensation Issue When Raining Causes Stalling)
-Rotor Button
-Condensation Cap For Distributor Cap (No Need For Sealant Now)
-K&N Air Filter
-Turbo Intake Hose (Original Had Disentegration In Spots)
-Exhaust Manifold Gasket (With New Locking Nuts and Sealant On Manifold Side, Not Block Side)
-Power Stage (Ignition Module or Ignition Stage Amplifier)
-Engine Coolant Temperature Sensor
-Gauge Temperature Sensor
-Knock Sensor
-All Vacuum Hoses
-All Coolant Hoses (Including Oil Cooler Hoses)
-Fuel Pressure Regulator
-Oxygen Sensor
-Catalytic Converter (Honeycomb In Original Rattles, Discovered Gone When Removed)
-Exhaust Resonator/Central Muffler (Original Damaged By Honeycomb, Sounded Like Broken Glass, Baffles More Than Likely Clogged)
-Idle Air Control Valve
-Starter Solenoid (Starter Tested Good)
-Power Brake Booster (Original Replaced, Failed 2 Out Of Three Brake Pedal/Vacuum Tests)
-Battery
-Radio Suppression Relay
-Throttle Position Sensor
-Fuel Filter
-Timing Belt and Tensioner
-Crankshaft Position Sensor (Last In Chain, Resolved No-Start For Now)
The following are checkpoints, mods, and maintenance:
1. Modded Airbox for more airflow, no codes present from OBD before or after
2. Cleaned MAF Sensor with MAF Sensor Cleaner, no codes present from OBD before or after
3. Checked EGR Valve - Diaphram not broken, free movement, appears functioning
4. Had EGR Pipe Rewelded - Pipe broke from connection to throttle body, completely sealed and functional, Minimal Carbon Removed
5. No codes from EGR temp sensor before or after
6. Checked EGR Vacuum Controller through OBD - appears functional
7. Checked Fuel Pump - Repaired frayed hot wire, sealed, pump fully functioning
8. Checked Fuel Pump Relay - Functioning
9. Properly adjusted Idle Air Speed - Steady Between 700-800 RPM
10. Checked EGR Pipe to Exhaust Manifold - Minimal Carbon Removed
11. Cleaned Throttle Body with Throttle Body Cleaner - No Soot/Carbon exiting system
12. Created Toggle with Fuse in between connection, connected to slot in fuse box, cuts off with car, slight battery drain issue before and after installation
13. Checked oil in case - oil change still new, no milky appearance suggested head issues
14. Removed and cleaned breather box - no oil deposits clogging operation
15. Checked charcoal canister - stalling in reverse happens with and without it connected
16. Checked muffler during disassembly of exhaust system - no honeycomb/debris present during testing
17. Car is at Top Dead Center - Timing
18. Fuel Injectors tested fine with OBD and Pressure present at rail
The following parts have not been changed yet:
-Charcoal Box
-MAF Sensor (No Codes)
-EGR (No Codes)
-EGR Vac Controller (No Codes)
-Compressor (No A/C, issue with stalling is unrelated)
-Power Steering Pump (Slight squeaking on rotation, PB Blaster in bearing area confirms, issue with stalling unrelated)
Other Issues : Slight battery drain coming from somewhere in the car, have to remove negative from battery for now
Toyota - Tacoma :: 1997 - Slight Stumbling / Hesitation Sensation
I have a '97 Toyota Tacoma, two-wheel drive. It has 154,000 miles on it. During the last three weeks, there's been a hesitation/ stumbling sensation happening occasionally in the first three gears. It doesn't happen in 4th or on the freeway. At first, I thought it felt more like a "slipping", like a clutch going bad (since I still have the original clutch).
I had my mechanic check it out, and it's fine. Here's a brief history of recent work done. Three months ago: injectors removed and cleaned out on a special machine. I replaced the cap & rotor and spark plugs. The wires were replaced last year. I replaced the fuel filter and PCV valve. I cleaned out and replenished my K&N air filter. Last week, I checked the connections where the spark plug wires connect to the cap. They seem fine.
Volvo :: Crank Pulley Timing Position For Volvo 940 Turbo?

Every once in awhile - very intermittently - when I press the close hatch button on the tailgate of my 08 Passat Wagon V6 4mo, it starts down and stops. I have to make myself watch it because more than once I have gotten in and started off. I only notice when I look in the rearview mirror and notice the unobstructed view. It seems to happen most often the first time I use it in a day but that is not consistent.

I have a 1997 Volvo 960 station wagon. It has been sitting in the driveway for 5 months. I went to drive it and it wouldn't start. We jumped it and it ran but wouldn't hold a charge. The battery was about 7 years old so we went and bought a new battery. We took the old battery out and replaced it and now it does nothing. It won't start and there is no sign of power to the car at all.
View 5 RepliesVolvo - V90 :: 1997 Wagon Horn Does Not Work
Suddenly, the horn on my '97 Volvo V90 (wagon - really a 960 wagon) stopped working. The mechanic checked out connections. The only thing he came up with was to get inside the column and see if a wire had come loose. Not only is that wildly expensive, but the air bag issue is a big deal. Finding a junk yard with a wheel, horn and column is impossible for this model. I have to pass inspection soon. Testing in and around the column? And, if after all testing is done, what are the options??

1991 740 Wagon 2.3 I4 with turbocharger and an intercooler.
My rear taillamp brake lights do not come on.
Of the 4 red lights on both taillamp cluster, only bottom two red lights stay on when I turn on the head lights. When I step on brake pedal with both headlights on or off, all 4 read lights do not come on.
I only get the middle small red light on. (which probably means the brake light switch on the pedal is fine.) I do have the lamp malfunction warning on when I turn on the headlamp or signal lights on.
I changed the lamp malfunction relay (big red cylinder) but things are the same. Found the bottom right red light had one of its filament broken so replaced the bulb but things are still the same.
Volvo :: 1999 240 Wagon - Removing Air From Cooling System
What is the trick to removing air from the cooling system? Today I replaced the water pump on my daughter's 1990 240 wagon. I filled up the cooling system and believe there is air in the system. The car gets hot immediately, when I squeeze the hoses they feel soft, particularly the lower hose. During the fill procedure, I was not able to find an air valve on the thermostat housing. I suspect there is air in the system causing it not to circulate.

I have a 1981 240 Wagon with 182K miles on it. When I reach 45-55 MPH on the highway the car starts to hum and roar. It is not horrible by any means but it has gotten louder over time and now the car kind of vibrates. At 60mph it stops and quiets down. Now I am unsure if I have a turbo or not and I feel like that could just be the turbo mechanism kicking in but I am not sure.

One of the rear doors on my 86 wagon won't unlock. The lock button goes up and down, both manually and automatically, but the door won't open and it feels as though it is still locked. I'd rather not cut a hole in the door panel! Perhaps I should have a locksmith get the door open and then I should remove the door panel to lube the locking mechanism? Is there any way to lube things without removing the door panel or consulting a locksmith? I can roll the window up and down.

All of the wiper features work except for "off". Speed controls work, rear works, washer works, etc.
