Sonata I45 (YF - 2011+) :: RPMs Suddenly Drop Off While Driving
2011 Sonata GLS, 95,000 miles.
This just started yesterday. While driving, the RPMS suddenly drop off. Depressing the gas pedal doesn't command any power output, even if I floor it, the RPMS continue decreasing and there is absolutely no power. The only way to keep moving is to completely release the pedal and then depress it again.
The transmission has been serviced twice by me and shifts smoothly. Should I plug a scan tool in ?
Corolla / Matrix 2009-13 :: Throttle Lag - Car Jerks As The RPMs Rise Too Fast
I've noticed the 2013 Corolla has a second+ gap between the moment you press the pedal and the engine RPMs actually rise. Most often, the car jerks as the RPMs rise too fast to keep up with my foot.
In fact, if I press the pedal all the way to the floor and release it quickly enough, the engine doesn't even react.
Caravan/Voyager :: 96 Plymouth 3.3L Suddenly Stalls - RPMs Drop To 0
1st problem is shifting from 1st to 2nd and sometimes from 2nd to 3rd though, 2nd to 3rd is not as bad as from 1st to 2nd. It stumbles and gets really bad if I don't let up on the gas. After the initial shudder it will go into 2nd just fine. I also have to gun the gas a little bit when I first start the car, or it will just sit there and idle and never go into gear.
2nd and more annoying is that it stalls after driving around a bit. It happens on freeway or city. It doesn't stutter or anything the rpm's drop to 0 and it just stalls and won't start up for a 5 - 10 minutes or so.
Codes pulled are P0731, & P0736. The transmission was replaced about 2 years ago with a refurbished one. Could it be going out again already? The guy at Autozone suggested replacing the TSS (Transmission Speed Sensor?) to see if that was the problem. I have not done this yet, but plan to.
Golf IV R32 :: When Shift Into Second Gear RPMs Go Down Fast
So after my 500 mile break in I decide to see what my new set up is made of. Had the kinetics stage 3 and the south bend stage 3 clutch installed. Did my first launch...everything went great. Got just a little bit of spin and the car took off like a scud missile. Right as Im going to shift into second my Rpms go down fast. No weird noises no metallic sounds nothing. No fluid under the car. Only a slight clutch smell nothing crazy. Car wouldn't go into gear. Shut the car off and it goes into gear.

I was running some logs to put into virtual dyno and I noticed that on all three the throttle value angle drops down to 33.7% between 3280 to 3380 rpm. Then above 6000 rpm it start to drop from 99% down to 91%. Even though the accel pedal pos is reading at 99.6. Is this normal??
For these I only logged 054, 115 and 031.
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.

View 11 RepliesGolf/GTI VII :: Loud Chirp Noise When Begin To Apply Throttle At 750 - 1000 RPMs
I have been experiencing a strange sort of loud induction/air turbulence/chirp noise right when I begin to apply the throttle at 750-1000 RPMs. It's the type of induction noise you would expect to hear from a car with an open filter intake if you shifted into 6th gear at very low speed(bogging, chirpy noise) Only been happening for a week.
I have an APR intake, and my initial thought was that maybe the tone of the intake had changed a little since it has gotten colder....but you actually cannot even hear the noise under the hood, let alone near the intake. It is only noticeable from inside the cabin. It happens regardless of clutch engagement and a/c. Car drives fine other than that.
It started happening with the soundaktor unplugged. I actually plugged it back in since then in hopes that it might mask the noise.

Golf IV / Jetta IV :: Passenger Side Coilover Loose / Little Movement When Wheel Is Lifted
So I just installed brand new coilovers and I quickly noticed a this problem. On the passenger side, when the wheel is lifted, I can feel a little bit of movement from the coilover and it really seems like it is the top bushing that is moving. I can see the metal top plate moving a little also. Everything is we tighten andI did the same thing as the driver's side but only this one does this. When the car is on the ground I can feel there is a bit of play in the wheel if I bang on it with my hand. Also, I know the gap on the top plates is normal, specially when lowered but again the passenger side looks weird and is much higher then the other side. What I'm I missing here ? Both side top bushing and bearing are also brand new.

I have a 2000 Subaru Legacy Outback with 208,000 miles. Last Oct I had a complete tune up done on it: fluids, filters, spark plugs, etc. Ever since then, the gas mileage has dropped from getting around 390-400 miles off a full tank to 290-300 miles off a full tank. I have tried carburetor and fuel injector cleaners and nothing is working. At this same time, it also started idling at 1750 rpms every time I start it, dropping down to around 750-900 rpms after I put it in gear. The timing system was replaced about 7 months earlier. So far the repair shops can't find anything wrong. I also just had the transmission rebuilt and it's still idling fast.
View 4 RepliesMercury - Sable :: 2001 - Suddenly Lost A Lot Of Power And Won't Go Fast At All - Bad Converter
I have a 2001 Mercury Sable with 114k miles. Just bought it and it ran fine for the most part until one day while coming home from work. It was still running but lost a lot of power and wouldn't go fast at all. I took it to my mechanic and he told me that this car has 3 converters on the exhaust system. First of all, I think having 3 is overkill and secondly, I am wondering why these things are so expensive. The one up front that mounts to my manifold is $350 just for the part. The one in the back can be bypassed (legally) but why did they make this system so complex and what are my options at this point? If I found a Sable that was being parted out, could I use the converters from that? Would it have to be the same year?
View 15 RepliesIntegra :: 94 Teg - Drop And Surge Throttle Cycle
A few months ago my teg started idling a bit funny. Its got a chipped ECU and has always idled very low (500 - 750 rpm) once warm.
In the past few months however the revs have started fluctuation or surging. Basically once the engine is warm the revs drop right down to nearly 200 - 250 (the needle actually drops off so its hard to tell ), then the engine bounces back up to around 500 rpm. It then does this non-stop if I leave the throttle alone.
Ive found that resting on the throttle tends to solve the problem as I'm forcing the system to run constantly, however when letting off the throttle (or dropping out of gear), she drops right down gets really ragged then bounces back up to ~500. The drop and surge cycle takes roughly 2 seconds.
Ive taken it to an auto electrician who sat on it for 2 weeks and eventually shrugged his shoulders. I've heard that one factor could be the O2 sensor, however another camp has said ECU and yet another said throttle sensor.
Details of the car are:
94 Honda Integra (GS-R model)
B18C (Gen 1) motor - Enlarged throttle body, Gizmo chipped ECU, better breathing with a pod etc.

I have a 2003 Passat and the engine temperature gauge will read 190 normally and then suddenly drop to almost zero, stay there for a while then head back up.
I purchased a temp sensor to replace the old but for the life of me I can seem to locate it. I know it's in the back or rear of the engine somewhere.
BTW, the car has the 1.8 engine.
Accent LC (2000-05) :: 2001 - Distant Drop In Power Suddenly
Basically I was driving along yesterday, no issues at all. about 3/4 of the way to my destination the car all of a sudden had a distant drop in power, a big vibration ran through the whole car at most RPM's and the engine/exhaust note is now best described as 'the Jetson's flying car'....although not that high pitched.
When I got to my destination, I pulled up to supercheap auto, checked the oil and there was a tiny bit at the bottom of the dipstick, so I topped it up to full but the issue still exists. After I popped the bonnet I also noticed a strong 'burning rubber' smell, but all the pulley's looked to be operational (could be wrong, didn't have a torch on me).
Got home, replaced the spark plugs as I thought a cylinder may have been missing, the first cylinder plug was black and oily, but the rest looked normal. So swapped them all out and the problem still exists, although not as severe.
Ford F-150 - 1997-2003 :: 1999 - Electrical Power Drop Suddenly?
It just doesn't end lately. I've noticed over the last several months, when it rains and I start the engine I would hear an underhood squealing noise. Like a belt or pulley. After the engine warmed up a bit, and the engine bay dried out, the squeal would go away. After a rain about a month back, I opened the hood to listen but wasn't able to locate the exact source of the squeal. Never gave it any more thought.....until this evening. I was driving in our New England Nor'easter in 4 whl drive mode with the wipers on HI, the defroster and blower on HI, and the headlamps and dash lights illuminated, when suddenly the dash lights dimmed about 40%, the blower slowed down about the same, and the wiper speed dropped as well from HI to about low speed. This was shortly followed by an underhood squeal which sounded a lot like the one I've experienced recently. After about 20 secs, the squeal would disappear and the power would quickly return to all accessories! This happened about 4 or 5 times and I returned home and parked it as I did not want to be stranded during the blizzard with a dead truck. The battery voltage gauge needle on the dash never seemed to move so I'm a bit stumped.
