So i have a 2010 gti stage 2 uni, when i have a half tank of gas or less when it reaches about 4000rpm it will loose power harshly that it almost makes u eat the steering wheel, but when it has more than half a tank of gas it drives just fine. I get low pressure fuel rail code when scaned with vagcom...
View 2 RepliesI 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.
Have a 96 Dodge Grand Caravan ES which runs great. However, when gas tank is half full or less, the car will, only occasionally, lose power as if it is not getting gas. Every few minutes you can start it and limp along for a minute or two at 10 mph and then it will die again. As soon as I can get it to a gas station and fill tank, it runs fine again. And this only happens once in a while - say like once every couple months.
View 5 RepliesI have been hearing a whine for a while now that has gotten worse. Today I was at a stoplight and there was a clunk from the rear and then the car lost about 1/2 of its power. I noticed the height level adjustment was blinking off. I shut the car off and it all went away after restarting.
View 2 RepliesMy fuel gauge acted pretty weird today. When I left my house today it was just above half a tank. I was sitting in traffic quite a bit and then looked down and it was below the e. I knew it wasn't empty so I kept going. Got to work. Went for lunch and it said full drove about 5 mins to eat and it went down to half a tank. What's going on? I am thinking of the fuel sender or wiring?
View 3 RepliesI've been having a very erratic fuel gauge issue as of about 2 months ago. My fuel level would register full, when in fact I knew it only had 1/2 a tank or so. Then 5 minutes later it would be pegged on full. Under a 1/2 tank the gauge would read any where from 1/2 to empty from 1 minute to the next. So last week I decided to drop my tank and take a look. I was thinking maybe my fuel sender was broken, maybe a loose wire in the tank, or even that my float had dropped off in to the tank.
After dropping the tank, I removed the PK-Up and sending unit and everything was intact. I placed my ohm meter on the sending unit and it checked out fine. So I took the Pk-up and rolled back up underneath the truck and plugged it back in. I had my son turn the key on and off while I moved the float to different levels in order that it would register. It registered empty, 1/4/, 1/2, 3/4 and full just fine as I moved the float to those levels. If you leave the key in the run position and move the float, it won't register or better said, the in cab gauge will not adjust with the movement.
You have to turn the key off move the float and hold it there, then have your assistant turn the key on and the gauge will show the position that you've moved and held it at. I simply removed the plastic cover from the sending unit, and sprayed it down real good with electrical contact cleaner. I didn't scrub the copper contact area at all.
I was concerned that scrubbing might remove more than I wanted to, and really mess things up. I attached an Ohm meter and checked resistance thru out the float travel. All checked out good and I reinstalled it. So now my fuel gauge is working as it should be. I did make a video while I ohmed the Sender Unit thru it's travel, but for some reason it won't load.

I have an my 2008 Golf mk5 R32 DSG. I have fitted the GruppeM Intake , done the decat and fitted a Milltek Resonated system. I am based around 1.12 miles above sea level and our fuel here is probably the equivalent of your 91. I had the car dyno'd yesterday with the graph below :
1. What is causing the horrible dip in torque and power just after 4000rpm? Do R32 graphs general look like this? Could it be a result of the variable valve timing?
2. I have a feeling my DSG's mechatronics unit is faulty , could that cause a loss in power or have a result on the dyno run?
3. The power does look low but if I convert it to coastal power it looks to be around 150wkw and 300Nm which seems right?
The biggest concern is the dip in the graph ... Power was measured at all 4 wheels ...
I just installed a boost gauge and drove the car a little and this is the readings I get. It starts off with 20 inHg and to normal street driving it goes up to 0 and down. However when I pushed it a little, the maximum reading I got was 11-13PSI (High RMP-almost redline). I am a noob in this boost department so Is this readings really accurate or is there something wrong? Recently i had some transmission work done. And since then the gas pedal feels heavier. I was convinced that it is from the new bushings but I feel like this is boost related. Because at 4000 RPM sometimes It suddenly looses the boost (Kick).
View 5 RepliesHesitation 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.
We have a 2002 Sante Fe with v6 and 270,000 km on it. Just had extreme loss of power and jerky acceleration from a stop. This has happened a few times in the past year and each time with a 1/4 tank of fuel? We pulled into a gas station, filled it up and away we go like nothing was wrong?
View 4 RepliesSo we were getting the annoying check engine light pretty religiously when we got to a half tank or less of fuel. In the trouble shooting I guess maybe there was a bad ground or something that required a little work then they told us the the intake flap motor was bad. Or at least was not returning the correct values.
So they ordered a new one and replaced it on Friday. I was looking at the paperwork, seemed like a fun job, pull the intake manifold, replace the part, put back together.
In the end, the experience with Emich VW in Denver was great. The service writer was awesome and you can even pick a tech to work on your car. I think that's a fine idea.
At seemingly random times when I take my Elantra to the gas station it will only fill the tank about half way before clicking off. After doing some quick google searches I'm leaning towards something being wrong with CCV system. I read that over filling the tank can cause debris to clog the system and a few months back my father-in-law borrowed it he has a tendency to overfill the gas tank. But I've also read that there's an error code that tends to pop up with it and so far there's been none. Either way I'm not familiar with how the CCV and related systems work.
View 3 RepliesI have a 2006 equinox with 74000 miles that consumes up to 2+ quarts of oil every 2000 to 3000 miles between oil changes and the water in the fluid section of the car drops about one gallon of water thus causing the car to over heat what could be the problem. The engine light always comes on when i have more or less then 1/2 a tank of gas. The manual said this could be the gas cap that is producing the problem and is there a solution.
View 8 Repliesabout 2 years ago, my 99 cherokee would start acting up at about 1/4 of a tank of gas...i would hit the throttle and it would lose all power like it wasn't getting any gas, it wouldn't stall out, but as soon as i would let off the throttle it would go back to running normal..... i filled the tank and it ran fine again.... i don't drive it much i've only put maybe 3000 miles on it since then, and now it's doing the same thing at half a tank now.... it even stalled out a couple times while idling..... do i need a fuel pump? a coil maybe? it usually runs great in the mornings when it's cold.... but when it gets hot out in the afternoon it starts doing it, or if its been running for a while....
View 10 RepliesI drive a 1992 Chrysler Imperial. It generally runs really good and I've only had a few minor problems with it. I try to keep up with maintenance for the most part and it only has100000 miles on it. I've had a problem with stalling lately - but mostly when I turn left. It only has such problems when I'm below a half tank of gas.
View 14 RepliesI was wondering why is it when I am going to get gas (full tank) while pumping, it will suddenly stop around half tank? And i know its half tank because i can see how much gallons its taken in. Is there a certain way of putting the handle in? So far its happened twice and its really annoying. Any reasons why it does that? Also does it on my dads toyota sequioa at times...

For last 5 months or so, I have to keep full tank of gas. If the tank is half, the car starts stalling, and the first sign of it is when I am taking a sharp right turn on highway exit. It's like the engine dies for a second or two and comes back when the right turn is over. If I keep driving and the tanks get lower, it will happen even without the right turn. I just fill up the tank and the problem is fixed.
Check engine light is on sometimes (but not always) with these codes P0171B and P0497, but I am not sure it's related.
There is sometime also a short delay in starting the car, irrelevant if the tank is full, (a second or two of extra cranking) but that might be a different issue too.
Its been happening often where it shows empty (when i really have half a tank) and my avg mpg resets itself. As I am driving it will go back to normal.
View 11 RepliesI recently acquired a 1983 F-250 regular cab with one previous owner and a known issue...the engine heaving for gas once it dropped to the half-tank mark.
Both fuel pump and fuel filter had been recently changed, among other small maintenance adjustments including new sparks and wires. In driving it down from the mountains following the vehicle transfer, the engine completely died at half tank. I then poured 2 spare gallons into the tank and it started up and finished the journey home. Prior to arriving home, I filled the tank completely and it only took 6 more gallons (19gal tank). So this doesn't seem to be an issue of a fuel gauge malfunction.
I'm perplexed. How is it that it can run fine at full tank, but upon reaching half it begins to sporadically shudder, as if not getting enough gas? If I continue to run the truck beyond half, it will stall or not start at all. Put a couple more gallons in, and it starts right up. When it's on half and won't start, it still fires with starting fluid. I suspect there's an air leak in some component in the tank.
I have a 2001 mercury cougar, every time the fuel gets to a half tank or below it stalls when going up a hill or around a curve, anytime u give it extra acceleration when it's a half tank or below it stalls and sputters, it's been in the shop for 3 months and got it out and ran good for a day now back bad I need a mechanics advice on what it could be other than fuel pump, fuel filter, o2 sensor, or plugs and wires... I've tried all of them...
View 1 RepliesSince purchase, I've had one gas fill up at 694 miles. That was four or five weeks ago and it's still full. My EV ratio is 65% (1100 miles) and will continue to increase. I realize I'm carrying a lot of dead weigh for weeks. For those with high EV mode use, what's your recommendation with gas fill ups? I'm thinking no more than fives gallons for daily commute and around town.
