Jetta - Volkswagen :: 2003 GLS Lagging On Acceleration Right Around The RPMs When Shifting
I have an automatic 2003 Volkswagen Jetta GLS with 138,000 miles on it. I bought her four years ago with 91,000 miles. Right after I got her, I noticed that she'll jump a little when when she's cold (i.e. ease on the gas for the first few miles until she drives more smoothly). Looking around the web, this seems to be fairly common and most forums say that it shouldn't be a cause for any alarm.
More recently though, she's started to lag when I accelerate right around the RPMs where she should be shifting. For example, increase to about 3000 RPM, then it feels like a second of free fall, then she'll catch up and be just fine.
I took her into a shop to get it looked at about 3 weeks ago - initial thought had been maybe an issue with the transmission fluid (did a flush back in 2014 / 110k miles). The mechanic refused to do the flush until I had the catalytic converter and downstream O2 sensor replaced. The previous owner had installed a modification to the sensor and the wires had got too close to the converter and melted.
We noticed the check engine light about a year ago and had it looked at, but the mechanic then said it wasn't a huge issue and was really only going to affect our gas mileage so we held off. Since this mechanic was fairly certain that this was causing our issue, we went ahead and had the repairs made. No luck. Haven't had a chance to take her back to the shop, but I figured I'd ask to see if we were at least on the right track.
Second issue. My wife and I share this car, and her commute is significantly further than mine. She says that four times over the past two months the car has shut itself off when it comes to a stop. Not a common occurrence given the amount of driving we do, but enough to be concerning.
I've had regular oil changes and kept up with the routine maintenance over the past four years (new spark plugs, air filters, etc.). Just got a fuel system flush with the catalytic converter repair three weeks ago. Haven't changed the battery since I bought her, but every time we get the oil changed they check it and say it's good.
Jeep - Compass :: 2010 - Losing Power / Hard Acceleration And RPMs Go Up
Our ABS light, anti-skid light, and engine light are on. The light came on when 3 year old son hit it. It just never went off. Dealership hooked it up to diagnostics and said we needed to spend almost 500 on a new ABS system. ALSO, at the same time, the car now sounds like its working very hard to accelerate. The rpm's go up, but there is no additional power. Is this connected to the ABS problem, or is this a transmission problem? Took it to a mechanic and he didn't check the transmission. After talking to him, he said it could be the transmission.

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.
Civic - Honda :: When Idling And Gets Up To Temperature RPMs Jumps Up And Down
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 RepliesAccent LC (2000-05) :: Gear Shifting - RPMs Instantly Jumps Up
I 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.
Honda - Accord :: Tac Momentarily Jumps Various Hundreds Of RPMs When Accelerating And Shifting
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 RepliesDodge - Engines - Dakota :: Hesitates / Jumps / Lags When RPMs Dip Down In Overdrive
My 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 RepliesToyota - Corolla :: 2000 - While Slightly Press Gas Pedal Engine RPMs Jumps
Car 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?
Ford F-150 (2004-2008) :: Rough Idle / Bad Gas Mileage / Stalls Out / RPMs Jumps Around
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.
Acceleration :: Car Sort Of Jumps Back And Fourth While Driving Uphill
Not sure if this is called "sputtering" or something else. But essentially today all of the sudden my car would sort of jump ahead, as if I when revving it back and fourth on the pedal aggressively. Not sure what could have caused this. Today was an essentially cold day so that may have something to do with it. Also my car overheats so I have to put anti-freeze in it most days. For the last few days I've been just using plain water, could this be the culprit? Why is my car jerking around like this?

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 RepliesJetta - Volkswagen :: 2002 - CEL Came On / Power Drop And Shudder
So here's a stinker that apparently has my mechanic puzzled. A few days ago I brought in my 2002 Jetta wagon in for a headlamp bulb change and a oil change. I pull out, but by the time I get home the check engine light is on. The manual says it's an emissions issue. I plan to make a garage visit on Thursday. they call me and say that they have my hubcaps...for some reason. OK, well, the next day, I am accelerating to get onto the highway, and suddenly, there is a big power drop and shudder. I pull over, call AAA and they take me into the garage where I got the oil change. Today, they say that a number of the spark plugs were out, but that it was strange because the corrosion made it clear that they had not been disturbed or pulled off in any way. They said that the spark plugs accounted for all of the car's symptoms. But we could not figure out how multiple spark plugs came out.

View 1 RepliesCelica :: RPMs On Car Drop Considerably While AC Is Engaged
It's starting to get warm again down here and I've started running my AC in the afternoon on my way home from work. I've noticed that as soon as I get off the freeway and sit at idle waiting for the light, the RPM's on my car drop considerably while the AC is engaged. I know there is a valve, AC idle-up valve or some such thing, that increases the idle when the AC is engaged. Where is it located and what is the proper name/part number so I can check or replace it? Haynes isn't supporting.

Passat (B5) :: 1998 1.8t TIP Sputters Only At Stops / RPMs Drop
I have a 98 1.8t TIP and this problem just started happening when I slow down to stop the rpm's drop and it almost dies but it catches it self and the needle bounces a few times and it is fine after that.
Also when I start the car the rpms bounce like three or four times but it again, catches itself and its fine after that... until i want to come to a stop again.. I live in the city and its a lot of stop and go.
Also when i slow down it feels like my car slams into first gear. it shift perfectly every other time up and down, only when it goes into first it hits hard and scares me cause I don't want anything to go wrong.
Golf/GTI VI :: Relay Clicking On And Off - RPMs Go Above 3k Then Drop Below 2500
So yesterday evening I was driving home and I noticed this clicking sound like a relay clicking on and off every time my RPMs go above 3k then drop below 2500. I am at 9Kish on the OD so I am just gonna let them know at the 10K oil change. Whatever it is or does, it isn't affecting the cars drive-ability one bit.
