GMC :: Power Loss While Idling But Not Completely And White Smoke
Sep 29, 2013
The car has felt like it looses power a little while idling but never has completely. we have had the oil light on for a week but hadn't checked it yet. then it lost power twice while driving so we pulled over and white smoke was coming out of the oil. we added a quart of oil but it would not start... the dip stick was still low, looked dark but not sludge. it might have been leaking the oil we poured in but that could be from the power steering leak we had. started it a few days later. the engine sounded like it was shaking real loud back and forth. What's wrong or should we drive it like that 15 minutes to the mechanic?

Replaced turbo stock with a wicked wheel. Truck smokes like crazy took turbo out rebuilt it and reinstalled in truck now truck pukes white smoke and has a of white smoke while idling. I don't get why. I've rebuilt injectors about two months ago. Truck is stock not bullet proofed at all. Truck has 170k head gaskets were done at 130k.

I have an 07 6.0 with 400,000 miles. Has been a great truck with no major problems. Before I started the work I had 3 bad injectors, running rough and the oil/ coolant temp just outside of 15 degrees. So I tour her down and replaced head gaskets, installed arp studs,all new injectors,all new glow plugs and new oil cooler. Ran great for a couple days. Then when driving to work lost power on and off for a few miles then completely gone could only go 10 miles an hour. I checked codes and there was the under boost code witch has been on there for a while and I forget the other code but it was for the ipr valve so I replaced the valve and right after still the same but that code went away and the p0470 popped up. So I cleaned out the ep sensor tube and replaced the valve. After several miles she now runs great but now I'm getting a little puff of white smoke when I take off and not every time and mainly when I take off some what quick. All codes are gone expect the under boost. I have an egr delete already.

Last weekend, I was riding my Golf 2.0L when it started losing power, then a thick blueish white smoke started coming out from the engine all the way through the exhaust. Stopped the car on the side of the road and had it towed back home. I've looked for loss of any oil or coolant but the levels are ok. No mixed fluids from sight. I've had a check engine light for oxygen sensor for a year or so, but I've been told that would not be the problem. I started the car a few hours after it was towed home, it was now cool so the smoke wasn't as thick. The smoke doesn't smell like coolant fluid. I took out a spark plug and there was a bit of oil onto it too. My engine runs normally. People have been telling me to look for head gasket, valve cover gasket, engine head, etc. A week later, I still can't find what it could be.

My 02 excursion is missing at idle and jars the whole truck around going approx 50mph feels like good amount of power loss but still pushing 30psi boost, just got autoenginuity all injectors buzz fine on the test, contribution test show balance fault in cylinders 1&8, should I look for o-rings to be bad, uvch, cups cracked or what ----- turbo fine, hpop great condition, new IPR, new fuel pump and hutch mod, about. 250k miles on truck nothing else major showed up on ae.

I just looked back and it has been since July 7th that my girl has been sitting in my shop. Well this past weekend I finally got her back together and started. It took a while to build pressure but she finally came to life..
While I am thrilled that she is running again i have low power before the boost kicks in and is idling rough with a blueish- white smoke coming out of the exhaust. Once i kick her a little she will get up and go but I've never had the smoke before.
I'm thinking maybe a bad injector???

I have a 2001 F450 7.3 chassis cab with just over 100k. I have a new problem... So far on two different occasions the service engine came on followed by a loss of power under a load and white smoke from the exhaust. Took it to the shop the first time, they determined it to be a dirty air filter, which seemed odd since it just happened all of a sudden. They changed air & fuel filter, problem gone- for two weeks..

99 Suburban LS 4x4 with the 5.7 with 109k miles. My Suburban broke down on my wife a few weeks ago, figured out that one of the catalytic converters had a catastrophic failure and came apart internally. I cut the cat off so that I could drive it the 60 miles home to save on the tow charge.
Had the cat replaced today and now I'm blowing white smoke out the tailpipe like I'm 007 throwing a smoke screen. The smoke alternates from smelling really rich to smelling like oil (pre-burn).
The oil pressure gauge is reading at or below 20 PSI and randomly (usually while breaking or stopped) completely bottoms out. I know cluster gauges aren't known for their accuracy but I also know this isn't 'normal' behavior. I also hear noise from the engine (possibly valves sticking but could also be more of a knocking sound than a clicking one). The oil is full (actually a little too full) and it went from looking like brand new oil to jet black in less than 30 days. I talked with the rep at one of the 'big name' auto parts stores and they recommended trying a 20W50 weight oil for a couple of months. Stated they have a similar vehicle with the same motor and made the switch a few years ago and hasn't had a problem since. I plan to do an oil change this weekend, I also bought an oil pressure sending unit that I'll change out at the same time. Am I on the right track?
Also, and most likely unrelated, my coolant temp gauge is totally inoperative and is just bottomed out no matter how warm the engine is. The coolant hoses (supply and return) are warm/hot to the touch at running temp so I'm sure coolant is circulating. What's the easiest way to check whether that issue is the gauge itself, the thermostat, or the sending unit?
There are no codes that come up on my OBD II reader at the moment.

Any known issues with coolant loss on these 1.6 motors?
Seems like I've lose a bit too much considering it's only got 30k on it now (bought it at 10k). Initially smelled coolant and complained but they said it was the undercoating burning off (new car coating) - which to an extent has been correct as I rarely smell it now.
That said, I have no visible leaks to my knowledge but it's still slowly losing coolant. I've yet to need to top it off as it's still between the hot and cold lines (yes I've checked on level ground and made sure to check both hot and cold for variance but it's clearly lower then when I bought it).
Now what scares me more then anything is that I notice a bit of smoke on start up. It does not smell like coolant but it's far more then I typically ever see from just moisture burning off.
I've had vehicles sit for months that don't smoke as much on start up. It will subside eventually but it just seems to be a rather excessive amount and unfortunately I can't tell if it is happening under acceleration, etc.
First though is coolant getting in / head gasket as the idle has been slightly rough....

I was having an issue with coolant loss and white smoke from tailpipe. Was told it was likely intake leak vs headgaskets. Changed intake gaskets, fixed the issue for a day then it started just dumping coolant from every available place in the exhaust system. Was draining a full collant bottle in about 2 minutes. Was also checking for exhaust in the coolant with the tube and blue liquid which it stayed blue. Had previously done a degas pressure test and it passed. The only test I hadn't performed was compression test which all the cylinders output was lowest 160 to the highest about 185. Did not perform a wet compression test as I was mainly looking for base compression and consistency.
Not sure what healthy is on these vehicles but considering they were all running pretty close I call it good. Also it idles just as smooth. Pulled intake a 2nd time and rechecked my previous work. Everything looked fine so I put it back together. Ran smoke free for about 50 miles now I'm back to smoke after it sits a bit but it clears up after a short drive. What am I missing? I will note that I had a small coolant leak from drivers side rear of engine that I noticed while it was parked in the shop. I'm assuming that would be the oil cooler? But oil is clean so it's not mixing. What other avenues on these engines can coolant make it into the exhaust? Drives perfect with no power loss.

I bought a 2004 power stroke with 100k miles, ran well for 15k miles then started having low power for first few minutes to no power, regular oil changes and fuel filters at 5k, checked FICM 48v KOEO , 48v cranking, new batteries just in case. Oil pressure when cranking at 50% of gauge , even crank cycle will jump when trying to fire, no loss of coolant, block heater working, it did start a few a few times and blew white smoke until warm then full power but the last 2 times I did get it to start it ran for less than 1 minute and died could not restart.
Fresh fuel additive in both fuel and oil for stickshion, have read hundreds of posts but not seeing similar problems no codes. With key cycle 120 amp draw on passengers battery for approx 25 seconds 48 amp on right battery glow plugs good due to the amp draw? So I think my FICM is good, good oil pressure cranking, the oil pump should be good, ICP good? Because of gauge coming up? Everything I read says black smoke for EGR soot issues. Not sure where to look.

it's now 1,500 miles away on the side of the road.White smoke, knocking and lost power. Truck has 133,000 reman engine installed at 46,000. Is it common for hydro locking to bend a rod? He sent a video and it def sounds like a rod and degas is empty.

I am a mechanic and tow operator running a late 99 f350 7.3 6 speed cab and chassis wrecker. This truck has had a hard life and has been neglected for quite some time, and now has become my baby/headache. Truck starts great, idles nice, and will run great for about 5 minutes until it starts billowing white smoke that smells like fuel and loses all power. If you continue to drive it it will die. Sounds like it's dropping cylinders and will barely idle. If you stop for 5 minutes or so and let it idle it will smooth back out and will run great again for another minute or two, then right back to stumbling.
Using torque app, hpop pressure looks good when it's running well. Peaks at 3k, IPR maintaining 30-40% max. As soon as it stumbles you can see the hpop drop to 5-600 and the IPR will climb to 65%. Let it idea bit and they go back to normal, and stay good until it stumbles again.
Ive changed the fuel pump, ICP,rebuilt FPR, change fuel filter, pulled and cleaned the fuel tank (metal tank, no delamination, looks perfect inside). Pickup screen looked good. Cleaned the IPR, cleaned the hpop reservoir, there was no screen inside. Checked voltage at fuel pump, 11.78 across the pump with it running. Pulled valve covers, no noticeable leaks around injectors. Injectors have less than 5k miles. Remans with 100% larger tips.
To me it seems like the lpop is not keeping up with the hpop under load, starving it until you idle and let it catch up. Could it still be bad injector orings? Bad lpop? Something I'm not thinking of?

I have a 7.3 Excursion, 234K Miles, 4R100 Transmission. Today I was in a rush to take one of our dogs to the vet, when I hit overdrive going up a hill, it almost sounded like a clicking noise and I was steadily losing power. I came to a stop sign and put it in park and it started to develop a constant lope that was rough. Whenever I would step on the gas it would put out white smoke which it has never done before. I was able to take it a couple miles before it did the same thing except this time it shut itself off.
Recently I have been having transmission issues as it feels im losing first gear. A while back I noticed it would idle slightly in park every now and then. A couple days before this happened, I came to a stop and my truck started loping slightly and first gear IN DRIVE felt very very weak. I have recently replaced the cam position sensor as well as the ICP sensor. I'm at a loss, I plan to do a ZF6 transmission swap very soon and this is only making me panic even more.
I never dog the truck, take it mudding, etc. Oil is changed every 3-4,000 miles. I did however get it scanned a while back and I believe two codes came up for two pistons, also did an injector buzz test and they all sounded strong.

I picked up a 2003 6.0 awhile back went ahead and did studs,gaskets, delete. Was driving it and seemed to lose power, started coughing and carrying on blowing bluish white smoke then shut off. Ended up hydrlocking #5, Oring on injector was tore when took out. Put all back together, ran horrible, did a balance test with AE, showed #3 injector, replaced, ran horrible, did AE dropped #1 injector. So in process of replacing the rest of the injectors. Just wondering why it is or was dropping them 1 at a time. Ficm was showing 47.6 to 48.6 volts, could that be it?????

I was driving my 2004 Jetta Tdi manual the other day and everything was fine. I stopped at a stop sign and began to go when suddenly i lost power like I was out of fuel only that was not the case. I looked behind me and saw lots of white smoke puffing behind me. I pulled over immediately and checked the oil (a little low), air filter (still pretty and white), coolant (clean and clear). I added a little oil and drove home very slowly and kept the RPMs as low as possible. There was no engine noise that I could tell.

Moving my worldly goods from California to Oklahoma in a rented 26' box truck with my wife following in our '02 F350 loaded to the gills with my lathe, mill, air compressor, weld and assorted machinery. Just west of Deming NM it started to blow lots of white smoke and down on power. Some rattling noises from the engine when throttled up & won't reach 3000RPM.
Had it towed to an impound yard for storage. Plan on sending a flat bed to pick it up when we get to Tulsa.
Any experience with a tilt back trailer capable of loading & transporting this truck that weighs around 17,000 pounds? My plan is to continue on to Tulsa & make arrangements from there.

My 1995 Toyota Tacoma has 217, 000 miles and was running great. The other day it started to make a whine when making tight turns. I had just climbed a hill and was backing it into a parking spot when the steering became hard to turn and a plume of white smoke began coming out of my exhaust. There was no smoke under the hood. I had it home immediately. I'm hoping it will not become a new planter box in my back yard.

yesterday I went out started my truck and white smoke started coming out my exhaust so I turned it off waited a bit started it back up let it run for a bit smoke went away drove it about 60 miles. Later that night it did the same thing but I was 2 gallons short on coolant drove it another 60 miles ran fine. Next morning decided to take it to a shop put more coolant in it drove maybe 20 miles to shop got there turned it off everything was fine never over heated once. So this shop is now telling me my trucks hydro locked and I steamed the EGR valve. And there telling me it's gonna be $8000 to fix it .
