Last night I was driving home... Cruise was set at 75mph. I noticed the RPMs jumping up and down slightly. I get paranoid. Anyways, its not that noticeable, but i posted a video... it seems to jump about 50-100 rpms each time.
Does rpms jump like that when set on cruise control? Ive never noticed it in any other car, and I am still getting used to this one so I want to make sure.
I have a 2012 VW GTI w/ a manual trans. It's a year old and has 15k miles. I bought it new from a VW dealer. Under hard acceleration, the RPMs jump about 500 RPMs for only a second or two and then drop down to where they were previously. During that time, it feels like the transmission slips out of gear and that I have no power. I've noticed this is gears 2-6.
Also, whenever I stop the car and put it into first gear, there's a loud thump that I can both hear and feel coming through the steering wheel and shift knob. It's been doing this since I bought the car. I brought it to VW and they said it's probably just because the gears are still spinning when I put it into first. But it still happens if I wait several seconds to put it into first.
Is this a sign of a bad transmission or one on its way out?
I just changed the engine in my 96 Honda civic, 1.6 base model. The change over went well and had no problems. When I have the car idle and it gets up to temp, the RPM's go from 2000 down to 500 then jumps to 2000 then down 500 again. When I put it into gear, drive or reverse, it stops jumping. What did I do wrong?
View 4 RepliesI have a 2005 Hyndai Accent GT automatic (83,000 km) and I am having a problem with the gear shifting. It's happening more and more.
As I am driving I am pretty sure that it's changing to a higher gear but when I slow down it seems like its not shifting down at all. Coming off the Highway I have to slow down and when I speed back up it seems like its still in the high gear. The RPM's instantly jumps up.
The only way it fixes it self is when I pull over and shut off the car and then start it up again and I am fine. A friend at work said that I may have to have my transmission fluid checked and filled up.
I have a 2012 Honda Accord EX with a manual trans. It's a fly-by-wire system. When accelerating and shifting, the tac momentarily jumps various hundreds of RPMs when the clutch is in. That used to mean you weren't coming off the gas when the clutch was in. I've been driving manual trans cars for 45 years. I know how to shift. But, it was a new car, so maybe... I paid close attention and was not screwing up the shifts. Apparently the computer doesn't realize the clutch is in and the gas pedal has been released. Is this normal for these cars? Is it a problem? (other than wasting a half thimble full of gas and over-reving the engine?)
View 4 RepliesMy 2004 Dodge Dakota V6 4X4 hesitates/jumps/lags (don't know what to call it, but it feels like something momentarily holds back the truck from behind) when I am starting up a hill. I start to loose speed/RPMs and give it a little gas, the RPMs don't change, then it happens. As soon as the transmission does down shift though, and the RPMs go up, it stops. This issue happens the most between about 40 to 50 mph and 1000 and 2000 RPMs. If I turn overdrive off then this problem does not occur even when the RPMs dip down below 2000, which in all fairness is not often. The truck has appx. 128,000 miles on it. What this could be?
View 9 RepliesCar is a 2000 Corolla CE.
When going at the desired speed (say 40mph) and there is lots of coasting room, I just let go off the accelerator and the car basically coasts. The engine RPM drops from 1600-1800 down to 900-1000 and it actually can coast a long way. Sometimes, I need to go faster (if I'm initially started at a slower speed) and when I press the gas pedal slightly, the tachometer shows the engine rpm jumps from the coasting 900-1000 to 1600-1800.
Is the tachometer (add on by ScanGuage) reporting it correctly? Is this a bad form of acceleration for the engine?
I bought an 04 f150 super crew cab with the 5.4L triton in it 3 years ago with 50k on it from my great uncle who was the original owner. It's had a tick to it since he had it but the dealership told him they couldn't find anything wrong with it and to get use to the noise. It's ran pretty good up until last couple months where it's been running really rough and not doing the best. It's still hasn't been all the time but more intermittent and comes and goes, but when it's running bad the rpm drops down to about 200 and my motor sounds blown.
When that's happening I could put in neutral and rev it up and it would go back to normal for a bit, but now it's all the time and stalls out even at 70 on the hwy. The codes it throws are, p1000- monitor checks not complete-more driving required, p0345- camshaft pos sens circ error(bank 2), p0022- A camshaft pos timing-over retarded bank 2. Things I have tried-changed all 8 plugs, added K&N air intake, replaced both cam sensors, replaced fuel pump driver module (due to corrosion). Tonight I'm going to clean the throttle body, mas air flow sensor, change fuel filter.
2007 5.4 . Starts good , idles all day. As soon as you try to rev it, it stumbles rattles etc. Shut it off, wait a second, restart then Idles fine. I watched live Data and it carries on when the VVT solenoids become active (above 800 rpm).There duty cycle goes to 60-70 percent while revving. I think it Is just one side of the engine. Could be VVT solenoids sticking on? yes ? No?
View 3 RepliesMy 2003 F250 6.0 It started about a month ago and got worse. Let truck idle for 4-5minutes and idle will jump a few hundred rpms. Got worse as it idles and cant figure it out. It eventually died and died once while driving but starred right back up.
View 1 RepliesI have a '99 Passat and this doesnt happen all the time, but - when I'm idle or accelerating after stopping at a stop sign/light, the car has a bad hesitation and it jumps, then finally goes with no problem. Sometimes it feels as if the car is going to stall out.
View 5 RepliesI have a 2012 Passat SE (5cyl) automatic with 25k miles on it. I have noticed that when i put my car into gear (reverse or drive) that my car jumps with a little burst of speed (while I am easing off the brake), I don't have the slightest clue of what it could be, or if that's normal or not as i purchased the car less than 3 weeks ago.
View 3 RepliesI'm worried about my beloved 02 Toyota Rav4. She's been a great car, we've driven all over the continent, never had a mechanical problem. Lately, particularly on humid days, my cruise control will stop working mid-trip and at the same time the RPMs start running high, nearly twice what they usually are. It lasts until I get home, next time I start her she's fine. The guys at the shop never find anything. The engine control module was replaced last year under an "extended warranty."
View 6 RepliesRecently I was driving on the highway, about 70 miles into my trip, when all of a sudden my cruise control kicked out and the rpms went high and then I lost acceleration. I pulled over to the berm and tried to take off. Problem is I could not get the car past 30mph because the accelerator pedal could. not be pushed down more than an inch or two no matter how hard I pushed. What could be wrong???
View 1 RepliesRPM's are dropping way off when coasting downhill while towing (as if the motor shut down), CC is on and maintaining desired speed. When at the bottom of the hill, all of a sudden, with a big bang(in the motor) the rpm's have came back up and you drive on down the road as normal. This seems to happen only when towing. "99 F250 7.3 I haven't pulled any codes as of yet. Whats happening?
View 14 RepliesI used to have LED brake lights in my taillights and decide to change them to old regular bulbs. After that Saturday 3am cruise control don't want to work. Then in the morning with all the lights off (headlights turns etc) the cruise works, as soon as I turn the lights on it stop working. I try to see the what's the cruise control fuse in the fuse card but I can't figure out which one is. 99 passat GLS manual trans.
View 1 RepliesOk so I'm driving again and the EPC ESP & CEL and "!" with the cruise control icon came on again. Car drove fine but I'm freaking SICK of this happening. I gotta get VWoA to fix this!!
View 7 RepliesI am looking to remove the entire cruise control system from my passat. Where the cruise control module is and what the cruise control module connects to? i know it needs a signal from the VSS, but what else?
View 2 RepliesRecently had coils changed due to recall. Car started rough when returned. Now epc,esp, cruise control, check engine lights all on. Error code po 173, 222 appear. It cleared itself then came back now car barley runs.Codes indicate throttle sensor switch high and low input. I hate to take it to VW. What is location of sensor switch?
View 2 RepliesMy Cruise control hasn't been working for a while now when i first bought the car it would work when it wanted to... sometimes it would work and sometimes it wouldn't or even sometimes it would work then all of a sudden while its in cruise it would just stop working
Now I want to fix this problem and get it to work again what should i start to look for, what could be some common stuff that I should look for I heard the cruise control is a PITA to fix once they stop working. I don't know much about the cruise control so where i should start and what I should look for first...
Where is it on the 1999 passat V6?
