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.
Elantra XD (2001-06) :: When Start Car Rev Up To 3k For About 3 Seconds Then Jump Down To Normal Idle Speed
So I just bought a 2002 Elantra with 72k on the clock (legitimate) and I'm having issues where the car will start fine in the morning and idle normally, however, say I come back to go somewhere else about two hours later, when I start it the car will rev up to 3k and stay there for about 3 seconds and jump down to normal idle speed. What's the issue?
View 7 RepliesDodge - Caravan :: When Put Into Gear, Doesn't Move And Revs Like In Neutral Then Jump Abruptly
Caravan acting like it was in neutral when she put it into gear and then jumping abruptly. She solved the problem by turning it off and back on. I think her problem might be the Speed Sensor b/c my Ford Taurus did the same thing for years: When put into gear, doesn't move and revs like in neutral, then suddenly jumps into gear sometimes. Problem could sometimes be solved by turning it off and on or moving gear shift to park and then back to drive. Also, even after warming up, when starting from a stop it would stay in 1st gear and not shift up, then suddenly shift up and car would jerk forward. Sometimes when it wouldn't switch gears the RPMs would remain high, even on highway. We thought we needed a new transmission! We found on line that it might be the speed sensor, which lets the car know what speed you are going. We switched it out and all the problems disappeared!
View 1 RepliesFord - Explorer :: 1997 - Stay Idle Kick Into Gear And Jump Start - O/D Light Flashing?
I have a 97 Ford Explorer. I bought it in 07 and it was nice until like 2 years ago when it started to give me doubts. It never died on me,yet, but everyday when I first start it for the day, if I put it in gear right away, it will stay idle for a while and then kick into gear and just jump. I would drive but it keeps kicking off and on until it is warmed up, I guess because it goes away. Also the OD light would come on also.

View 5 RepliesGolf V R32 :: Start Then Going To Stall - Revs Don't Climb Very High At All
I posted awhile back about my R not wanting to start. It will start, just not turn over right away, but it will start the first time. However, it feels like it's going to stall out because the revs don't climb very high at all (1k at best) when it usually goes just over 1k to start, then drops down to 5-600rpms.
Yesterday, after it sat in the hot sun for nearly 3 hours, it cranked but didn't start right away. It had started right up when I left my house to go to the gym, and I drove it 5 miles to the gym.
Then again, this morning, after it had been sitting outside all night, I went to start it and it just didn't sound right when it started, like maybe fuel wasn't getting to the engine.
The car has 31,500 miles on it, has had all recalls done, and the battery checked out last month. The battery was fine, so it's not the problem. I have been doing some research on this issue, and have come up with the following things to have the dealer check:
-fuel pump
-fuel pump relay
-coil packs
-crank position sensor
-fuel pump fuse
-fuel filter
-injectors
-alternator
-starter motor
-crank angle sensor
-cam sensor
-check all grounds
-check fuses
And to top it off, I just drove it down the road and the sunroof randomly opened on its own. I have never had that happen before! Do you think the two are related at all? I'm just wanting to make sure what to tell the dealer when I drop it off later this afternoon. I ran a vag-com scan last night and there were no electrical or engine fault codes found, so I don't know what is up with it.
Golf VI R :: In Cooler Weather Revs Don't Go To 1200 Rpm At Start Up
It is pretty common knowledge that when we start our cars they initially rev to ~1200rpm for a minute or two and slowly drop down to just below 800rpm. I generally use this as the "warmup" time for the car and try not to drive until the rpms drop. But lately in this cooler weather (<20F) when I start my car the revs do not go to 1200rpm, they start right around 800rpm and don't fluctuate. Why this might be happening?
Last winter I did not pay attention to the revs so I can't confirm or deny that this happened before. But I do notice it only in cooler temps. If it is much above 30F the car will start like normal.
Only engine mods are APR stage 1+; VWR intake and APR HPFP.
Golf IV / Jetta IV :: Revs High Between Shifts And Randomly Doesn't Start
I bought this car and I've changed out the Clutch Position Sensor, the black one on the clutch mount. Started to work and start but now it's doing the same symptoms as before. So here is what is going on.
1. Randomly doesn't start, full power comes on, and fuel system turns on, immobilizer works just fine as far as I can tell (key light turns off)
2. Cruise control doesn't work (which lead me to the CPS)
3. High revs between shift, once I push the clutch to shift it revs up high, I noticed that if I stay under 3k it doesn't do it as much, but if I go HAM on it it revs up about 1k rpm more than at shift point. But if I shift nice it revs about 2-400 rpm.
It's been tuned by C2 Motorsports, done by a certified mechanic, that's the only mod on the car, besides suspension. I bought the car and dropped 1100 to fix it to drive right, newish throttle body, and a major vacuum hose, and the tune within a month of getting the car and the tune was to mainly flash the ecu so it wouldn't pull two codes for a leak that wasn't there anymore.
Tiguan :: 2010 - Hesitate A Little Bit And Jump Slightly When Idle
My check engine light came on around 2 weeks ago, had the code checked, it read P0302. Noticed it started to hesitate a little bit and would jump slightly when idle. About a week after that I had a friend, (who used to be a mechanic at Lexus and for the Army) switch the coil on cylinder 2 to 3, then the code moved to the 3 cylinders. The next day the CEL started flashing this time, checked the code again and it was back to P0302, switched all the sparks plugs.
CEL was cleared and hasn't come back but I know something is wrong..but the car still loses powers when driving and jerks/misfires when the car is first started up but after it runs for about 5 mins or so, it doesn't do it anymore while sitting idle. I have a rental car right now and will take it soon, just really swamped with work. I'm just fearing the worst until I get time to get it into a mechanic.. and just hoping to hear something less dreadful than a repair... that's why I did the minor things first, my friend thinks it may be a more serious issue. The report from AutoZone (the second time I got the code scanned) said this. But this is not 100% accurate correct?

Ford F-150 (2004-2008) :: Multiple Electrical Malfunction - No Start Occasionally Then Jump Start?
My F150 4X4 would not start a few days ago, after only having turned it off a few minutes prior. The gauges would sweep wildly and get stuck at various positions. I checked the fuses and they were fine, then unplugged the battery for a bit and it started back up. Occasionally it won't start and i'll have to disconnect the battery again to get it to start.
I'm still having some strange electrical issues though. The radio no longer turns on unless the ignition is turned to AUX. My back up alarm for going in reverse doesn't come on anymore. The gauges take at least 10 seconds to wake up after starting the truck. The dashboard blinker indicators will randomly stop blinking or making any noise. I was thinking it could be the computer, but could it be something else?

I did a tune up on my 20th last week, plugs and coil packs and oil change. now i have a strange idle that it wasn't doing before. i checked all the plugs over again and they are gapped fine and i have no CE light on. Every now and then my RPM meter will jump down and then right back up, same with the boost meter at the same time. i had it looked at at the garage i go to and they said they cant seem to find anything wrong. What might be causing the rough idle? keep in mind this only started happening RIGHT after the tune up.

I have a 2000 Toyota Celica GT-S.
When ever it is idleing and i hit the gas it bogs like its going to stall but then revs up. Difficult to get out of first because of the bog might stall it. My check engine light came on and it said rich fuel as well as oxygen sensor. Do the oxygen sensor would cause this because their are 2 and are expensive if I change it and turns out not to be the prob.
Toyota :: 1992 - Galloping At Idle / Revs Up And Dies Down
At idle (like at a stop sign or sitting in the drive way) my '92 Toyota revs up and dies down (kind of a "brrrrvvvvvv-buh... brrrrvvvvvvvv-buh") We have been fixing it up and got ahold of another Toyota that has a decent motor but the body, frame, and everything else is shot. We are pulling a starter out of it and was wondering if the part that causes the gallop could be replaced too.
View 4 RepliesSanta FE SM (2001-06) :: Erratic Idle - Revs Up And Down From 1200 To 2600 RPM
Daughter's 2001 Santa Fe Delta V-6 2.5 engine, needed lower ball joints. Replaced the entire lower arms as more cost effective & actually a bit less work, for me anyway.
So While under it, see oil dripping down back of engine. Decided to replace valve cover gaskets. So I start to disconnect all the involved connectors, brackets etc to pull the Upper air intake to get to the rear cover.
While moving around, find most of the hoses & vac lines baked brittle and dried out and loose even tho clamped, so I replace all of those, plus the PCV valve., & the upper & lower radiator hoses as well. I only removed the upper 1/2 of the intake. I change out the cover gaskets, reassemble every thing, reconnect all the connectors. I noticed that some of the connectors could apparently be switched to other sensors, but since all the lines seemed so backed solid, they actually retained their positions to go back onto the proper sensors.(at least I hoped so & it seemed that way).
Anyway, every thing back together & tightened up, so I start it up & the idle is at about 3000 to 3400 RPMs. WTF? So I pop the throttle a couple of times by hand and finally it drops down to normal, then just as suddenly, it begins SEARCHING for lack of a better word, and starts racing upto 2600 rpm then drops to 1200 then up again then down again.
No check engine light or other idiot lights on. So I shut it down & check all the connections and hoses, nothing disconnected or left off or loose. I start it again, and it immediately begins running high & low searching for the idle again.
I shut it down again, and put the MacPro scanner on it and NO codes either set or pending. I next check the Haynes Manual I have for it, & the closest thing I can find to my problem says: Engine Lopes while idling or idles erratically 1) Vac leak 2) Leaking EGR 3)Air filt clogged 4) Fuel pump not delivering enough fuel 5) Leaking head gasket 6) Timing belt/sprockets worn 7) Camshaft lobes worn
By process of elimination, not #'s 2) According to service manual, there is no EGR valve on the 2.7, and I couldn't find one either, #3) Air Filter is new & clean, #4) ran fine before I worked on it & with the engine revving up to 34 or 3600 rpms, getting plenty of fuel, #5) Have had many head gasket problems over the years on many vehicles, never anything like this, and again, it ran fine until I worked on it #6 & 7) Doesn't seem to me to be a belt sprocket or cam shaft problem, as none of that was touched & again, it ran fine until I worked on it. This kind of narrows it down to #1, for me, but this is not like any vacuum leak I have ever come across in 45 years of auto repair. I have found & fixed many stumbling idles due to minor leaks but never had anything like this.
I next called a friend who owned an automotive machine shop & who I used to do work for, and now runs a highway dept garage for a municipality who has been a certified mechanic for many years, told him all the above & the only thing he could come up with was a MAJOR vacuum leak, like possibly the upper plenum gasket rolled up or got torn some how when I replaced the plenum and he suggested that I try a smoke test.
Scratching my head, I go back to the car, & break out my home made smoke machine that I use to successfully pinpoint leaks in emissions systems. I ran it for quite awhile, and found some light smoke leaking from somewhere down around the head, but due to the construction of the engine & no way to get the light to shine under the plenum, could only guess that he may have been right & that there may be a large leak down at the lower intake manifold to head gasket. Needless to say, I removed the upper plenum again, & this time also the manifold to heads, and the gaskets looked like they may possibly have leaked slightly between the ports, & quite possibly somewhere around the number 6 cylinder. So I cleaned the surfaces & am putting on the new gaskets that came in the set with the upper plenum to manifold gasket set.
My questions after relating all of this:
1) The 2 gaskets between the manifold & the cylinder heads have a blue stripe around all 3 cylinder port holes (appears to be some kind of sealant or factory applied silicone bead) & there are no markings of any kind anywhere on the gaskets, so do the blue stripes face DOWN to the heads or UP to the bottom of the intake manifold ?
2) Regardless of which way these stripes face, should I use any kind of high temp sealant around the port holes in addition to the gaskets, or just install them dry ?
3) Can the Idle Air Control on the Throttle Body Fail & affect the idle like the problem I am having, but NOT set a computer code ?
4) Can the Throttle Position Sensor affect the idle like this and NOT set a computer code?
5) I also found an electronic valve between the Air Intake & firewall, it is labeled PCV and has an OEM part number after that, I believe this to be the Purge Control Valve, which connects the TB to a plastic line which I believe runs down to the emissions canister under the vehicles front seats. Am I correct in thinking that even if this part had failed, it would have NOTHING to do with my erratic Idle problem, but would throw an emissions computer code?
Subaru - Forester :: 2002 - Revs In Idle / Hesitation On Accelerating

View 1 RepliesFord Ranger / B-Series :: 2001 / 2.3L - Misses At Low Revs And At Idle
My new-to-me 2001 Ranger 2.3L runs great except for this one problem: At under 2000 rpm, if I give the gas more than the gentlest tickle it misses and bucks until I back off. It also misses at idle. There is no CEL but I did pull a P0442 code which points to the evap purge valve. At above 2K rpm, it runs like a champ and I can floor it, except when under load such as climbing a hill.
Could this be the problem, or should I look elsewhere also? I'm not one to just throw random parts at a problem. The previous owner thought it was old gas or an injector, but I would expect it to run poorly all the time. The service writer at the Ford dealer thought it sounded like an electrical issue, but coil, plug wires and plugs are new.
Tiguan :: 2009 - Revs Drop To Idle When Cruising And Taking Foot Off Gas
I have a 2009 Tiguan Auto Diesel and have noticed recently that, when cruising along, if I take my foot off the gas pedal the revs drop to idle. The revs only pick up again if I touch the accelerator. Im sure it did not used to do this. If you feather the gas pedal to maintain a set speed (say 50mph) then this can have the effect of the rev counter dropping to idle and going up again to, say 2500 rpm all the time.
The rev counter seems to be all over the place!!! I also had a stall situation the same day. I was leaving a driveway to join a main road. The driveway is on a slight incline when exiting. I nudged up to the kerb line as normal and then took my foot off the gas to check noting as coming. Nothing was so I accellerated gently and the car stalled. I think this is related.
The Tigual Auto box is not DSG it is regular Auto and it is also 4motion. I have noticed the haldex doing its thing in D2 when pulling off, you know that weird bit where the revs drop a bit even though the gear is not changing. This is a little similar to that but not the same....
