Mazda :: 2003 - Tachometer Jump When Driving In Higher Gear
I have a 2003 Mazda 6, 5-speed. Whenever I'm driving in higher gear (4th or 5th), the tachometer seems to jump. For instance, if I'm driving at 50mph at 3,000rpm in 5th gear and I want to accelerate to ~65mph, the tachometer seems to jump to 3,5000-4,000rpm, then drop down to 3,000rpm and then slowly increase as I accelerate.
What's the reason for this random jumping/revving? I don't think the clutch is going bad or slipping. It only seems to happen in higher gears, even without me shifting--only when I want to accelerate.
Golf V R32 :: DSG Slip / RPM Jump Up For A Split Second On Tachometer When Press Accelerator
Had my .:R for 2 years now and just noticed other day. When you cruise in 2/3/4/5 gears about 3000 RPM and suddenly press accelerator 1/3 down RPM jump UP for a split second on tachometer. They go up by one segment (which is 200RPM) and then drop back down.
Now, DSG should not do that to my understanding as clutch pack is engaged! There should be no slip. Also, it is not a drive train shunt, as I kept the car in very slight acceleration.
Camry :: 2004 Engine Never Starts And Tachometer Does Not Move
My 2004 Camry will not start; I have never had any starting issues before and the car was running perfectly hours before the problem started.
The battery is fully charged
The fuel pump is operating
The ignition and fuel pump fuses and relays are good
When I attempt to start the car everything sounds normal, but engine never starts and the tachometer does not move.
Additionally a soft buzzing noise starts coming from somewhere near the air filter box. The sound can be stopped by removing the "EFI" fuse. Disconnecting the injectors does not stop the sound.
Chevrolet - 3500 :: 1993 - Truck Starts Surging / Tachometer Jumping From 2000 To 2500 RPMs
Mechanics say they don’t know what wrong… I had some transmission work done on my truck – mostly an leak and replacing the harness – and ever since then after it rains or if we have a heavy dew my truck does the following:
Driving from O to 49 miles an hour truck is fine, as soon as I hit 50 the truck starts surging and you can see the tachometer jumping from 2000 RPM to 2500 RPMs. I drive around 17 miles to work where my truck will sit for seven hours. On the way home the truck is fine. I find this to be more of a problem when the truck has sat for a day or two over the weekend without driving it. Sometimes the “check engine” light will come on, sometimes not.
I have taken it to two different places and neither one says they can find anything wrong with the truck. I have driven this truck for over 11 years and know it very well. There is something wrong, but what? 1993 Chevy Silverado 3500 Diesel....
Passat (B5) :: 99 V6 Starts To Flutter And RPMs Jump Up And Down
I have a 99 V6 original owner with 177,000 miles. The car has all the usual work done for its age and miles with one cam tensioner and associate seals, gaskets, water pump, etc.... Getting some burn oil smell and believe the other tensioner is starting to leak but it's not bad. Replacement of the cracked AC coil was difficult...
Lately when the car is in higher gears, light load, and RMPs around 1,400 to 1,800, the car starts to flutter and the rmps jump up and down a couple of hundred and you feel the car lurch a bit. It's not harsh. Feels like a miss but you don't feel much engine jump or knock. Under hard acceleration, the RMPs are smooth and no lurching.
When I back off down to 1,400 or 1,500 and accelerate easy, the problem returns. Sometimes I feel it up at 3,000 but not as pronounced. The car is not throwing codes.
All ignition components are fresh in the last year with wires, pugs, etc... I still need to get this car to 250K...
Golf V R32 :: Idle Starts Off Evenly At About 700 RPM Then Jump Up To About 1000
OK, I'm coming to the end of my first month of ownership. Have put on about 1,000 miles (need to drive this thing more - it's so much fun!)
Anyway, once the car is warmed up - I come to a traffic light and sit at idle. Idle starts off evenly at about 700 RPM. After a minute or so, it seems to jump up to about 1,000 RPM. Can feel it "pull" a little. After a bit of time at 1,000 RPM, it seems to drop back to 700 - but not all the time.
Mentioned it to the dealer and got a response like, "they have these things cammed". I don't think it's a cam issue. Just wondering if this is normal behavior or if there is an adjustment or part needed.

My X keeps needing to be jumped and after being jumped it runs like a top as usual. Took it to Autozone and had them hookup their little portable doohikie and told me the battery is fine but the alternator should be pushing out 14a and it's only pushing 13? Didn't realize 1aI made that big of difference but whatever. I am taking the alternator off in a few minutes and I'm gonna have it bench tested to confirm the output.
Is there a heavier duty alt that I can get? I will be pulling an RV before too long so I'd like to get one that's gonna last. Btw, 2000 excursion limited v10 gas 6.8...
Ford F-150 (2004-2008) :: Battery Keeps Dying / Starts Up Easily With A Jump And Then Works Fine For A While
I have a 2004 Ford F150 and the battery keeps dying. We do not use the truck a lot and it sometimes sits outside for 2-4 weeks without being used. If it sits that long, it might be completely dead, but starts up easily with a jump and then works fine for a while. The battery is a 650 amp Motocraft w prorated replacement from 37-100 mo. The local Ford dealer has checked it several times in the past 2 yr and said it is fine, and that if the truck sits for a couple of weeks the battery will die. Is that right? I am not a car moron, nor am I an expert, but I am concerned that they are missing a small draw somewhere in the system. Should I be concerned about a draw or is this just something that happens to batteries as they get older?

Truck was dead- 2001 F250 V10... Has a starter relay (solinoid) behind battery... put a new relay in there- no go- cleaner terminals... then I put key in start and shorted the 2 terminals in the relay and she cranked right up. That would mean the starter is still good correct?? something in the ignition system?

View 5 RepliesMitsubishi - Montero :: 1987 - Engine Starts Missing / Sporadic Skipping
I own a 1987 Mitsubishi Montero 2-door, 4x4, vin # JA7FJ23F9HJO30272 with a 5 speed manual transmission. It's powered by a family 2.6 T2FFC3 engine with CID 1.55.987.
My problem occurs quite sporadically, sometimes after driving 100 miles or so. Then, the engine starts missing as if you were turning the ignition off and on very quickly. Most often I have to limp back home by getting spurts of acceleration along with skipping.
Some technicians say the bushings are worn out in the distributors shaft housing and some other technicians state it may be a carburation problem. However, I am desperate for a solution to solve my problem, and possibly better my fuel economy to more than 12+/- miles per gallon.
Is this a common problem of these vehicles with high mileage? Do you have a solution to resolve my problem? My vehicle has 132,059 miles as of this writing.
Nissan - Maxima :: 1994 Runs Rough Occasionally / Cylinder Starts Missing
1994 Maxima SE 5 speed manual with 178k runs great when engine is cold, then a cylinder starts missing. Symptom is worse in low gears. Then, miles and miles without a miss. Replaced rear ignition coil and it seemed to fix the problem... for about 20 miles, then it started missing again. And stops missing… for miles.

My truck is a 2003 f250 / 2wd automatic, 7.3 powerstroke, 284000 well maintained miles.
Just last week I sprug a large oil leak and had to replace the hoop outlet o rings..problem solved. This week I can drive 15-20 miles on the freeway and the truck starts to act like ota running out of fuel. Bogs down to 40mph then starts missing. I pull over, and when revving I have un burnt fuel and oil smoking out of my tailpipe. I let it sit for 5-10 minutes and it will be fine for the rest of the drive and this happens intermittently, there is no pattern.
The truck has a ton of power, starts great hot or cold. I did a ton of research and found a IPR could possibly cause this, as could plugged screens in the fuel pickup. Then I read about all the injector harness issues but I don't think that I my issue.
Toyota - Matrix :: Tachometer Usually Bouncing Between Zero And About 4k
I drive a 2007 Toyota Matrix, automatic, 111K. My check engine light is on, but I haven't had it check because it frequently comes on and off for the evap sensor in the gas cap.
a few months ago all of a sudden the tachometer would move around very erratically. it started the first weekend that it was really cold here, and has since come and gone. At the times when it's not working, when i start the car the tachometer will usually hang at zero for a while and then begin to flail around usually bouncing between zero and about 4k. Occasionally it will make it all the way to the highest range of the gauge, 8k, and jump around there for a while. Then without any trend that I've noticed all of a sudden it will function correctly. There are also times when it works fine the entire time from the time I start the engine.
Another disturbing piece is that about a month ago my temperature gauge joined in and will now remain at zero the entire time the tachometer is flailing about and then when simultaneously they will begin working normally.
Golf/GTI VI :: Tachometer Recently Stopped Working
The tachometer in my 2010 golf recently stopped working. it just sits at 0 RPM's no matter what. I'm not sure if it is a fuse or something else has gone wrong. I'm not even sure which fuse to replace to try and fix the problem.
View 1 RepliesSonata I45 (YF - 2011+) :: Tachometer Does Not Move At All When Cruise Is Set
When I drive normally using the pedal, I can see slight movements of the tachometer as the torque converter locks and unlocks (this is normal when lifting off the gas and pushing it again). However, I notice when my cruise is set that my tach doesn't move at all, it doesn't matter if I'm going downhill, uphill, or whatever. It stays frozen wherever it's at when I hit the "set" button. Maybe the torque converter stays locked when the cruise is set? This isn't a problem, it just seems odd to me.
View 4 RepliesCamry :: 1993 - Manual Transmission - No Tachometer
I have just acquired a 93 Camry with manual transmission and no tachometer. However, I have a auto one that I am wrecking with a tachometer which I want to fit to the manual vehicle which I will keep in commission.
Where it is connected to the engine wiring? Is there a sender unit? Or does it sense pulses from the distributor?
The service manual that I have does not describe it.
Ford - Taurus :: 2005 - Tachometer Won't Working
2005 Taurus. 82K miles, 3L, 6cyl, OHV engine, auto transmission. Occasionally the tachometer goes crazy. When this happens, it seems like the car loses some power. The reading on the tach is definitely incorrect when this happens (needle all over the place). Replacing something called the "speed sensor" ??? Couldn't find anything else that this problem may point to ??
