Golf IV / Jetta IV :: Losing Boost / Power At High RPMs In High Gear
2003 jetta gls 1.8t 5spd - gts stage 1 tune(gonzo stage 2)
tt 2-1/2" downpipe with high flow cat
turbo smart splitter valve(set to divert only)
turbo inlet pipe
homemade intake with k&n filter
stock n75 valve (f)
So in first through 3rd gear my car gets 20psi of boost then at 3,500 ish rpm smoothly starts to lower down to 15psi. but in forth and 5th gear the boost drops faster, enough so the diverter valve actually opens. then the boost will bounce up and down, around 15psi. the car still accelerates but with obvious power loss.
Is my diverter valve not "firm" enough? it is adjustable, so I've tightened it as much as it can. it doesn't seem to change anything. it came with spring spacers to make it tighter, but I haven't tried that yet.
Is it something with the tune? not enough fuel, need bigger injectors? The problem is only at about 100mph, so its not a big deal. I would like to get it straightened out if possible.
Golf V R32 :: Unable To Maintain A Steady Speed And Then Losing Power
R32 has 29,000 miles. I live at 8000ft. Recently, my R, when traveling back from sea level, starts to have what seems like fueling issues at around 7000ft. These take place by the car being unable to maintain a steady speed and then losing power. Once power falls you can press on accelerator and then will pick up again and accelerate through the gears until you need to back of the accelerator, then the same problem will happen... Once home after lurching around like a kangaroo the car will be fine if switched off and then left for an hour before driving again.

I was driving on the highway in my 2001 jetta (332000 km) on the cruise control yesterday and suddenly it just started slowing down and stopped. Putting my feet in the gas did nothing . Before stopping completely the battery light came on. After won't start anymore, just making a sound like it is trying but turn in the butter. To be honest the check engine has been on for a while but we are pretty sure that is the glow plugs because it is a recurrent problem... Nothing else light up and there was no sound or smoke.
View 3 RepliesAstro - Chevrolet :: 2000 - Running Rough / Hesitating And Losing Speed When Accelerate
My 2000 Chevy Astro van started having problems whenever I accelerate, hesitating losing speed, and all I can possible tie it to is a new gas station where I filled up which said "May contain ethanol". I think the "service engine light" flashed on for a second but does not stay on.
Could bad gas or the ethanol be the problem? Would getting the problem codes read at a parts place work?
Golf IV / Jetta IV :: Steering Wheel Power Loss - Unstable At High Speed
I have a mk4 TDI. Running 18" 225/40 and coil overs. My car began to have a loose steering wheel and was unstable at high speed so i did alignment and it was bad. when they fixed it next day it broke again. My front wheels end up being too open. If front left is straight than the front right is too much open, like i am turning right. i did alignment again in the shop, they made them straight and it broke again next day. What can cause that my allignment breaks every day? Shop doesn't know.

2011 6.7 with 3.55 gearing. Just got the truck. And it seems when its cold the truck will rev high in 3rd gear and then sort of fall into 4th gear sort of losing power for a split second. If I gas it hard, its not as bad. Usually only happens like I said when its cold. Check the trans fluid its full and looks clean. My guess is some sort of sensor or the computer???

Diagnosing our 2006 Hyundai Sonata.....2.4 L engine....automatic.
While cruising along, about 40mph and up I guess...when traveling at a steady throttle and engine speed... if you ever so slightly give it more gas, sometimes it will act as though it is losing power for a second and then kick back in.....but revs will stay up....
I was thinking either throttle position sensor or (gasp) transmission.....it doesn't really feel like a slipping tranny....but wondering if it is issues with the overdrive...
Chevrolet - Tahoe :: 2003 - Reduced Engine Power Message / Speed Losing
I have a 2003 Tahoe that I love but is driving me crazy with a "Reduced Engine Power" message. I am driving along and suddenly it dings at me, the message center says "reduced engine power" and I am losing speed. It goes into a "limp mode" in which I cannot accelerate, it cannot pull itself up a hill, and the engine misses badly. I can pull over, shut it off for a couple of minutes and then start it up and run again just fine until it decides to do it again.
There seems to be no rhyme or reason, one day it did it 4 times w/n the first 20 miles, then ran 100 miles w/o doing it at all. I recently took it on a trip that normally takes me 1 1/2 hours, it took 2 1/4 hrs that day because I had to pull over so many times. I was having to stop every 3-4 miles by the time I got there. My usual mechanic has completely given up, told me to trade it. I have had it to another mechanic for over a month now, 3 times he has thought it was fixed, but it wasn't. One time, I didn't even make it the 5 miles to my house before it acted up again.
One other note on this: this past trip I made, I left early in the morning and my lights were flickering high/low. . . this went on for several miles. Finally my lights quit flickering, then I lost engine power, pulled over, shut it off. When I started it back up, the lights started flickering again. The cycle seemed to continue, once the lights would settle, the engine would lose power. I took it to a parts store and had the battery and alternator checked. They said both were fine. (Had never noticed the light thing before, but I can't think of a recent trip after dark.) How I can pass along to my mechanic?
Ford 6.7L Power Stroke Diesel :: 2016 F350 Started Losing Speed Down To About 58 MPH
I have a 2016 350 dually with 6.7, with 2,200 miles. I was pulling my 11,000 LB travel trailer on fairly level ground, major interstate going 65mph. Noticed I started losing speed down to about 58mph, then started decending a long 5-6% grade, at this point I was running at 3/4 throttle to maintain speed. It felt like something was binding like the rear or engine was seizing up. No codes, all temps were fine. Transmission stayed in 6th gear, even at 3/4 throttle.
Checked trailer brakes, didn't seem to be dragging. Engine sounded like it was really laboring like it was tightening up. This lasted about 10 minutes, very slowly power seemed to return to normal but it was not noticeably changing. Fuel was 3/4, DEF was filled about 300 miles earlier. This truck since new feels like it has 150HP less than my 2011 F250 with the 6.7 I traded it on. Not sure what to do, if I take it back, if they find nothing then I'll get a diagnostic charge.
Golf - Volkswagen :: 1995 - When Accelerate, Revolutions Goes Up But Speed Stays Same
I got an automatic VW Golf 3 1995 75ps for my wife, Basically it was a gift, the car is in OK conditions, motor works very decent and for my own amusement the thing actually drives great! The only problem is in 3rd gear, the car change between gears clean and very tight, the problem is when the car accelerates the revolutions goes up buuuut the speed stays basically the same, until I put my foot out of the pedal and reaccelerate, then slowly it works fine but as soon as I put some power on it, it slip, very frustratingly BTW! There is no worrying noise, no smoke, no leak, I haven´t measure the ATF mainly because it is impossible in this car! It is supposed to stay closed forever! (?). My main question is if the ATF can be related with this issue or is it other component of the Transmission? Second question is if the ATF is not related then what can it be?

I have a 1999 7.3 with 260k miles. It is all stock with the exception of straight pipe. I got the truck about 8 months ago and have put about 5k miles on it. Have never had any issues with it. I was driving from Dallas to Houston and about 45 minutes into the trip my truck lost power. I was going about 65-70 mph and the service engine line came on and I lost power. It was running rough and was blowing white smoke. I let it sit for a couple minutes and started it back up and ran fine until 30 minutes later. It did this 2 more times on the way to Houston. Oil is good, coolant is good. Not over heating. Threw a code the first time but didn't throw it the other times. I brought it to a mechanic and he thinks it's the Wastegate.

Accent LC (2000-05) :: 2002 Slow Acceleration / Seems Like Losing Power
I have a 2002 accent 1.6.(272,000 miles) It has been having this issue for awhile now. It is very slow to accelerate, seems like it is losing power. Also if I press the gas pedal hard it does not want to shift correctly unless i back off the gas pedal some and then it will shift fine. I have had the transmission checked and it has no issues (transmission has be replaced with only about 80,000 miles on it). Also if i try to run the AC it really looses power. It currently does not have any diag codes when I have it scanned. So far I have replaced spark plugs, ignition coil, fuel filter, and a diode that I was getting a code for. I am just curious if there is something that could be causing the issue that will not report a code.

I have a 2000 z28 Camaro, and I'm having problems with it slipping at high speed. and I noticed today that fluid is leaking and the car loses power as it warms up. it runs great starts right up, just having problems with the tranny. What may be going on, I do check the fluid and fill it when it needs it. and it runs great until I need to get up to around 50mph.
View 1 RepliesAccent LC (2000-05) :: A/C Not Working - Condenser Fan Won't Go Into High Speed
I have a 2005 accent gls. I use the car for deliveries so a lot of stopping/starting. when the car is hot, the AC compressor will shut off after 5 seconds, and not re-engage until about 20 seconds, then only on for 5, so not keeping cool air. I noticed when I turn the AC on, the condenser fan (i think) kicks into high speed so I assume that's what it should do, but when the issue is happening, it does not go into high speed. the shop I went to wasn't able to determine the problem. they checked pressure and evacuated the system. when it works, it blows cold as it should.

I have a 2000 Ford Ranger, small v-6, automatic, no AC, windows, door locks, this has a heater and radio. This truck runs fine until I try to climb up the mountains (Colorado) and at app. fifty mph the engine starts sputtering and losing power. More than just an engine ping. When I run on flat ground while pulling a fifteen hundred pound load it runs fine with no sputtering or loss of power. Mechanics here are stumped.
View 8 RepliesSanta FE SM (2001-06) :: Losing Power And Hesitant - Idles At 1500 To 2000 Rpm
I have an 02 Santa Fe with the 2.7, 4x4. This started a few weeks ago. When it is first started, it cranks over for a few then starts, idles 1500-2000 rpm. It is a little hesitant at first, but will eventually run fine. If I go to the store after it is warmed up, shut it off, then go back to start it again after shopping, it does the cranking over for a few, and when it starts, you can smell gas (strong smell). when you go to take off, it hesitates real bad, backfire rumble through the exhaust, has no power, bucks, and you have to feather the throttle to keep it running. If you put your foot to the floor, it does nothing, 20 mph if your lucky. if you can keep it running long enough without it stalling, which it has done, and hit the highway, and get going, it will eventually work itself out and run ok again. There is NO CEL. It is getting worse.
View 1 RepliesCamry :: CE 2000 5S-FE With Code P0770 And High Idle Speed
Camry 2000 CE 102,xxx miles. My car died in Jan 14, after have P0770 for while, only Reverse gear work. The mechanics said the tranny need to re-build. I had him bring the tranny to tranny shop to re-build ($1650), then the code still pop up. Brought it back, they said the ECU needs to be reset. I had the car next day then that code pop up again!
They replaced the Solenoid E. The code is still there. Brought the car back, they took the tranny to rebuild it again. Drive the car for a day, the darn code pop up again, now they blamed on the ECU. Ok my mechanic guy replaced it at my own cost for part ($150) but the code is still there. This time they blamed on the high idle rpm approx. 1600-1800. My mechanic tried to fix the high idle speed so the tranny stop blaming other causes. He cleaned IAC valve, replace O-rings (I don't remember the location of them) then he said whenever he inserted the new ones, they start to crack!
