Chevy - Malibu :: 2003 V6 3.1 - Coolant Loss / Loud Knock / Loss Of Power And Misfire?

I have a 2003 Chevy Malibu, V6, 3.1, auto, 140k miles. Car started out with code 0420 with no noticeable symptoms, but then added code 0303 (miss fire cyl #3) with loud knock (mostly after warmup) and loss of power under load. Now internal loss of coolant (no puddles or external drips). Changed plugs and wires - no change - all plugs looked good with no sign of contamination. Questions - if this is a valve/piston/lifter problem (which would explain the knock, miss-fire and loss of power), why would I get the loss in coolant? If the loss of coolant is fouling plug #3 (which would explain the coolant loss, miss fire and loss of power), could that give me the loud knocking? I don't see how a valve/piston/lifter issue would cause a leak in coolant but I also don't see how a coolant leak into cyl #3 would give me such a loud knock. Do I have two different problems? If it is a leak into cyl #3, is there any way to tell if it is the intake manifold gasket (which leaked before and was replaced five-six years ago and which I could do again if I had to) or a blown head gasket (which I don't think I could fix or afford to get fixed)? Engine will occasionally get hot (but not overheat).

Volvo :: Gas Tank Has A Leak On The Top

My boyfriend has a Volvo with 100,000+ miles, not exactly sure what year, but he recently found out the Gas Tank has a leak- ON TOP of the tank. We scratched our heads and tried to figure out how this happened. How did this happen? He does normal city driving, hasn't have an accident or bump into anything. He took it into the mechanics and they said it would be around 3000 repair/replace. How the tank got a leak on the top?

Volvo :: MPG Falling As Fuel Tank Gets Lighter - Readings?

Due to my working within city, I hardly drive on highways so all my mileage readings are city readings. Recently I noticed that the mileage measurements at 3/4 full tank and 1/4 full tank were different. When I fill up the tank with 3/4 full and 1/4 of full tank left are very different. At 3/4 full, my city mpg is at 16mpg however when I fill up the tank with 1/4 of fuel left, the mileage is at 14 or less. This happens repeatedly. Could this be the sign of fuel pump dying?

Volvo :: Gear Shift Got Stuck In Neutral - Control Rod Loose From Transmission Lever

Volvo Automatic 1992 240 - So, just started to back out of the garage and, all of a sudden, my gear shift got stuck in neutral and then started shifting without engaging the transmission at all. Pushed it back into the space and, taking a look underneath, I realize the control rod's completely detached from the lever in the transmission.

I can re-attach it, but it just comes loose again when I shift. It seems like something should be in there to hold the control rod in place with the transmission lever, but I don't know what because I can't seem to find any documentation on what everything should look like down there.

Attaching a couple shots, one with a circle around the area that's coming un-attached since the angle's a bit off.

Golf IV / Jetta IV :: 2005 - At Half Tank Power Loss?

I have a 2005 jetta 2.0 Once it gets under half a tank I lose power, it acts like it's running out of gas. It only does it in warmer weather (this started in march when we took it to Florida, once it got back in the cold weather it didn't do it again until 2 days ago when it was in the 70's). I took it to he mechanic I've used since I got the car (he works exclusively on vw and audis). It didn't do it to him in the two weeks he had it, he couldn't find anything wrong that would cause the issue.

He did do a complete tune up, replaced both of my fans and coolant. I ended up replacing the coolant temp sensor myself since that decided to go bad after I got it back. It lost power after getting the car back again warm weather and just under half a tank of gas. Prior to the Florida trip the water pump, timing belt and starter were replaced. I had my fuel pump replaced in 2014. It is an automatic with 157k miles on it.

Prius (2004-09) :: Hesitation And Power Loss - Water In Gas Tank

Hesitation and power loss have returned. I removed all four spark plugs and found that the spark plug on the driver side of the engine, or side closest to the inverter, and its coil pack were covered in dried/sticky oil with no loose oil present around them. Pics added to new post #11 of coil pack and spark plug.

I couldn't find anything that really matched the symptoms I was having this afternoon on the way home from work. After letting the engine idle for about a minute to get through Stage 1, I pulled out of work but noticed I kept hearing a slight whining from the inverter (radio was off and windows were down) while going uphill on the road out of our parking lot. Speed was in the range of 25 to 30 MPH.

Torque showed I was pulling between 10 and 20 amps from the HV battery but what I noticed that was REALLY weird was that the timing advance gauge showed I was running around 2 to 3 degrees (?) instead of normally being around 13 or 14+ depending on how quickly I'm accelerating.

And the more acceleration I demanded, the the more amps were coming from the battery and the RPMs on the engine would go up, but the timing advance still remained below 10 degrees. I didn't hear any knocking but I could definitely feel the lack of power.

Volvo :: Oil Loss But No Sign Of Leakage Or Burning

I can see no sign of oil leakage or oil burning. The car runs great, about 159M miles. Yet, it goes through 4 qts of oil every 1000 miles. If you don't check it frequently, it suddenly is 'dry' and takes several quarts to bring back on the stick to full. There is a little puff when first starting of light smoke, then nothing out of the ordinary.

Volvo - 240 :: 1988 - Coughing And Stalling And Power Loss

Recently my old workhorse started coughing and stalling. This isn't consistent at all. I'll be driving and the car will lose power and come back to life. It also stalls at stop signs. Brought to my mechanic and left it for a week with him and he can't figure it out. 1988 Volvo 240 over 200,000....

Volvo :: 94 850 Turbo - Sudden Loss Of Power When Put The Pedal To The Floor

Took my 850 Turbo out on the freeway today, and when I put the pedal to the floor on the onramp there was a very disconcerting loss of power just as the turbo was really kicking in. No issue under mild to medium boost, but when pushed hard there is a short loss of power/hesitation, almost like a backfire, then boosts again, then the same power loss until I back off on the gas. Cannot get full boost without this happening.

Volvo :: 2000 S60 Power Loss And No Start / Whirring Sound

The wife was stopped at a light in her 2006 S60 and when the light changed and she accelerated the car stalled and died. It would not start and thus I had it flatbedded back to the house. Id been told at the dealer during a service trip ($$$) that the alternator might be going bad as it was making a whirring noise and was given an estimate to replace it, the serperntine, pulley, etc.. of $1300. At the time it wasnt a driveability problem and being a working stiff I didnt have the 1300 to spend so I decided against doing the work. Thus, when the car stalled I figured it would be the alternator causing the problem and draining the battery.

I recharged the battery overnight figuring I could get the car turned on then remove one of the battery terminals to verify faulty alternator. However, car would not turn over, Id only get what sounded like a click from the starter. Fine, I figured, the alt killed the battery so I went and purchased a new one and installed it. Car would still not start and Id still get the click from what I believe is the starter. Tried the old bang the starter with a hammer and still nothing. Checked the connectors to the starter and all seemed ok.

At this point, the dreaded "my wife seized the engine" thought popped in my head. I then tugged a bit on the serpentine and noticed the crank turn slightly so Im pretty sure she didnt seize the engine. (fingers still crossed on that one).

Volvo :: 1992 240 Wagon Intermittently Stalling / Missing - Loss Of Power

My 1992 240 wagon (injection) is intermittently stalling, and missing. The lambda light is on the dash. Last year it was doing something similar, but not as bad, and I took it to Volvo and they cleaned the throttle body and said it should be ok, and it was for a while, but now it's worse. Ignition parts are mostly new, I doubt it's that. When it stalls it nearly always starts straight away. When it's missing badly but not stalling, pressing the acc peddle does nothing, until it eventually catches on and revs properly.

I also find that when I have a full tank it's not so bad. When the tank was nearly empty it was particularly bad - it's winter and I was suspecting there was condensation in the tank.

Is there a 'backyard' way of getting the error codes? This could be a good start.

Passat (B5) :: Smoke Heavily Right Under The Coolant Tank

Whats under here that can be causing my car to smoke? During the week I dont drive it much just because I drive and take home my work truck, but when I start it up and let it run it smokes pretty heavily, right under the coolant tank but more to the rear. Other then a valve gasket what else could this be? Also comes from that opposite side but not as heavy.

Prius (Gen 2) :: Coolant Tank (close To Radiator) Empty?

I just noticed this morning that the coolant tank (close to radiator) is empty. The other coolant tank level is normal. Big surprise! I thought they are connected, and coolant can flow between them.

Santa Fe (DM - 2013+) :: Coolant Tank Is Completely Empty

Was under the hood today and noticed the coolant tank is completely empty. Car hasn't overheated or anything...just odd that it apparently wasn't filled correctly from the factory. It should be in the middle of the high and low markings, correct?

Prius (2004-09) :: Coolant Pump Still Failed Early With Loose Drive Belt

I loosened coolant pump belt when my gen II prius had only 200 miles on it. I retensioned it approximately 70% less. Where I could turn water pump pully by hand breaking traction with drive belt using all my strength.

The ice coolant pump just started to leak at the weep hole at only 63000 miles and 5 years old. I was sure the reduced tension would make coolant pump last much longer.

After retentioning it (brand new at 200 miles) I could deflect belt about one inch as opposed to not able to deflect belt at all!
