Audi - A4 - Transmissions :: 2006 - Engine Hangs Around 1700 RPM When Trying To Maintain A Stable Speed
May 1, 2015
Recently bought an Audi A4 Quattro from a dealer with 112,876 miles on it.. The car runs absolutely beautiful, it up-shifts and downshifts without any noticeable issue, it changes gears without any issue, however... When I am trying to maintain a stable speed of around 35 - 40mph and my engine hangs around 1700RPM it'll bounce up and down slightly..
The revs will hop between 1700RPM up to around 1750RPM and then back down, and then up again.. It's hardly noticeable and the only time it causes any issue/delay is when it hops above 2000RPM and then back down... Is the torque converter the issue or what else could be the cause? Timing belt has been done, spark plugs have been checked, oil has been changed.

When I'm on highway (between 90 and 120 KM/H) I heard a whistle when speed is stable. it happen frequently in the last week. I notice it happen approximately at 95 and 110 KM/H. When I remove my feet from accelerator, I don't hear the noise anymore.

Our 2006 Prius (175,000 miles) has recently suffered intermittent periods of diminished ICE power. For instance, for about 1 hour recently driving a hilly section of I-81 through eastern TN, the car was struggling to maintain 68 mph and the HV battery stayed mostly drained at 1-3 bars. Gas mileage was falling, but no misfire. After stopping at a rest area, it was fine. No OBD codes and ICE seems OK otherwise. Experienced a similar reduction in ICE power a few days later. Dealer has no clue. Similar experience I've had with another car was when it's catalytic converter became plugged, but that was not intermittent.

I've noticed when trying to maintain a low speed (25-35mph) the car doesn't really like that... Almost feel like the brake is being slightly pushed on and off, or the car is losing power. It's been most noticeable around curves when coasting but having to give it a bit of gas to maintain speed. Shifting overall doesn't seem bad, so it doesn't feel like a tranny issue. I've also sometimes noticed the opposite. Sometimes when coasting then pushing the brake to slightly slow up it almost feels like the throttle is very slightly being pushed. Not sure if I'm having powertrain issues or just not used to the way this car drives. It just get most annoying when trying to maintain 30mph in city and the car occasionally surges a bit.

My cruise control will engage but not maintain set speed. It slowly loses KPH, 10 KPH every 30 seconds. What to look for?

I have '98 Transport Montana and I took it on a trip last weekend on the expressway. I would be doing 70 MPH and approach a hill and start depressing the accelerator to maintain my speed and I could feel a chugging. Also, I could hear the engine seem to make a change in its sound coincident with the chugging. The RPMs at this point were around 2K. It's a 3.4 and all of the normal stuff has been maintained properly (spark plugs, filters, etc.).

R32 has 29,000 miles. I live at 8000ft. Recently, my R, when traveling back from sea level, starts to have what seems like fueling issues at around 7000ft. These take place by the car being unable to maintain a steady speed and then losing power. Once power falls you can press on accelerator and then will pick up again and accelerate through the gears until you need to back of the accelerator, then the same problem will happen... Once home after lurching around like a kangaroo the car will be fine if switched off and then left for an hour before driving again.

I recently picked up a 2001 Nissan sentra. This car sat since around 2010. I guess the previous owner had a lot of work done by the dealer a year or so ago and it looks it, brake pads etc. are brand new, a couple other things look new but he's not a car guy in the slightest and can't find the receipt nor will the dealer give him one due to computer system change and I actually tried with them myself, that's correct.
Anyway, the check engine light is on and bringing it home we had reports of black smoke out the exhaust. It also felt like it wanted to stall at times when stopped but it never did. Well, I ran it a while and at times it seemed like it wanted to clear up, at others it didn't but the light stayed on and what not. I scanned it and it claimed the O2 sensor 1 bank 2 was bad so I replaced it.
It didn't make any difference so I cleaned the Mass Air flow sensor. Again no good it's the same. Here's the funny thing though, it's great first thing in the morning usually. As the day goes on and as we drive it, it gets worse. What I can try/change next?
I'm almost leaning on electrical issue where it gets worse as the day goes on and dew dries off. I'm new to Nissan's, I like the car and really want to work this issue out. I did replace the fuel pump when I got the car, and have run sea foam through and actually on that tank of gas it ran pretty good but that's worked itself out now.

Middle of May, I went to Boston. On the way there, I started to notice a slight whirring noise that was only present when I gently feathered the gas to maintain highway speed. If I were to apply any more throttle, the noise would go away, and if I were to pull my foot away and allow engine braking, it would also disappear.
So I did my best to finish the trip to and from Boston adjusting my driving to avoid the noise. Once I came home, I researched and thought the noise might have been my wheel bearings (I had just replaced lower control arms, lower ball joints, inner and outer tie rods prior to leaving for Boston). I also had a shop install my upper strut mount bearings and bushings simultaneously with the wheel bearings.
Since then, the problem still continues. It has grown louder, but still occurs under the same situations. I've focused more on it and here are the conditions under which it occurs:
1. Car must be warmed up. Starting it up cold and allowing SAI to run then driving, car is fine, no sounds. Usually takes 20-25 mins of driving to get it to start making noise.
2. Car still only makes the noise when the gas is being feathered (ie barely pressing it enough to give it any sort of throttle. It does also make the noise between shifts when reengaging the gear and applying gas, as the throttle pedal passes the point of throttle off to throttle on.
3. I'm hearing more noise now during engine braking than I had been previously. Could be related?

Problem I'm having, when in overdrive my 04' F150 FX4 5.4 Triton surges while trying to maintain a steady speed during power delivery to the wheels, it causes a shuttering and bucking effect. If I push the button to turn the O/D off, the RPMs rise and problem goes away. During the problem no CEL illuminates and tach stays constant. Fluid condition & level are okay. (not burnt) I'm completely baffled since there is no code in the ECM to point me in the right direction. I do use the truck to occasionally tow my 5k lb boat & trailer. When I began towing I did not know to turn the O/D off and put some miles on towing in overdrive, I know now that was not good for the tranny.

I've been watching my mother's 1976 Fiat convertible this summer. It had been taken to the shop about 6 weeks ago and it's been running fine without any problems. I had to leave for about three weeks and now the car will not start.
When I turn the key in the ignition with the clutch engaged, the engine turns, but pressing down on the gas pedal has no effect. The engine doesn't rev nor does it catch. There is gas in the tank and clean oil. I checked all the connections I didn't find anything loose.

What may have wrong with my trans on my truck... this is what its doing, I am able to put in drive and drive it for so long then its like the truck is in neutral and doesn't gain or maintain speed. but i can turn the truck off and put it in park and restart the truck and it will go again?? that is how i got it home....
the fluid is burnt now but wasn't that bad until the trans started doing this. I have pulled off the pan and inspected the filter and it does have metal debris in it, pulling the valve body off tonight before work (work 3rd shift) to inspect that, i think it has something to do with the solenoids or valve body because it actually moves but then quits until i restart the truck. Also does the transfer case use fluid from the transmission? or are the fluids separated between the 2.
Truck has 4.0L SOHC with a 5R55E in it 4WD...

I have an 2006 Super Cab that has 72,000 miles on it. Stock everything except for Magnaflow exhaust and Hankook Dyna Pro tires. Last month I noticed some weird "hang" ups with the steering when turning and it just seemed to be a bump or something while turning. I was gone on vacation last week and started the truck after a week of sitting and the steering acted like it was binding or hesitating. It almost felt like a tire was down, got out and check pressures, everything was good (high if anything and got it to the right pressures).
After driving it got no better potentially worse. I start a turn and it is fine but at a certain degree it starts to bind and seems like the power steering is not there. It does not return to normal position easily either. I have checked the fluid and it is fine, the belt is normal (and original) with no tears, or rips in it. Not sure where to start, but have a couple thoughts of power steering pump going or front end has issues? Best description of the problem is that it is a binding feel and happens both left or right turns. Have to force it like the power steering is out.

I have a 735iL with comfort start. Intermittently the starter stays engaged after the engine has started. I then turn the ignition off, the engine and starter stops. I can then start the engine as normal on the second try.

The engine light came on with only 1700 miles on it. Is there a check list that I can go over to find the problem. I want to check it out myself before I take it to the stealers I mean dealer Or is there a way I can check it on the MFI?

I have a 2008 Mazda3. The car has a replaced engine with 24,000 miles on it. The engine was put in before I bought the car.The car and engine run like a top; except at certain RPMs and when in gear. When I have the car in any gear (auto), the engine makes a rougher noise at RPMs 1400-1700. As I apply more gas, the RPMs seem to get stuck at 1700, then it will break through and run smooth 2000+ RPMs. The engine sounds perfect at all RPMs except 1400-1700 when in gear. When I have it in park and rev the engine, the engine sounds perfect at all RPMs.

I have a 2008 F150 with a 4.6 litre in it. Last year I dropped a couple of plugs and had a factory new, second generation 4.6 installed. The motor only has about 25,000 on it while the rest of the truck has about 160,000. I was driving back roads in western Mass and went over a small, about four inches deep, pothole. I was driving about 35 miles per hour.
I didn't get any associated master warning lights. The RPM started rolling back from about 1700 to 0, and when they got to 0, the engine shut off. There was no previous sign of a fuel pump going bad, or of a bad fuel filter, which is also less than a year old. The truck has plenty of electrical power and turns over strong but won't start.
I checked the #9 fuse as identified in the manual but couldn't find an actual relay for the fuel pump, so I'm assuming it just has the 20 amp fuse which was good by the way. I'm thinking that the fuel pump would have given a few warning signs, but maybe not.
I did check the emergency fuel shutoff switch to make sure that it had not activated when I hit the pot hole and unless I'm resetting it incorrectly, it doesn't seem to have been set off.

I have a 06 f350 with 5.4 140k miles. Recently it has been shaking bad on idle but only in gear and it's hard to start when cold. The exhaust is moist at all times and the fluids never leak. When you floor it it hesitates feels like it's overly rich but if you let off a little it stars to pull again. Also while cruising at 1500-1700 rpms in any gear it will surge and skip. Only time it will miss and the CEL comes on is over 4000 rpms for a random misfire. Just put new coils in new fuel pump and filter. There has always been a cat code but it never effected the drivability. Could it be injectors?

From stop. When I accelerate it takes a long time to get to drive. It feels like a lag time. What is wrong with my car?

96 Ford Explorer, 78,000 miles After about an hour on the highway (60 mph), the vehicle slows and cannot increase in speed. It does this until it slows to less that 20 mph. Pushing on the accelerator increases the rpm, but does not result in an increase in speed. It only does this after an hour or more on the highway (city driving does not cause the problem). No one can diagnose the problem; already took the vehicle to the dealership and a transmission specialist (both said nothing was wrong). Hoping very much to keep this vehicle.

I own a 1999 Honda Accord w/160K miles. This past summer my car would occasionally stall while driving at slow speeds (when the car, an automatic transmission, was in low gear). Usually I'd be able to start it right back up with no problems. In some cases I'd have to hold the ignition switch for about three seconds. As the weather cooled in the autumn (I live in New England) the problem disappeared. However, in the last couple of weeks the problem has started up again only now I have trouble restarting the car. I have to wait a couple of minutes before it'll start up again. It has the feel of a flooded engine. The car also idles rather low...at around 800 rpm. I don't think it's a battery or alternator because all of the electric apps.(power locks, windows, radio, etc.) work after the car stalls. I'm bringing my car in for regular maintenance but would like to know what to tell my mechanic to look for.
