Ford F-150 (2004-2008) :: 2005 - Idle Really Rough / Revs Will Rise And Then Drop Again If Blip The Throttle
I just locked out the cam phasers on a 2005 f150 with a 5.4. It now idles pretty rough. If I blip the throttle the revs will rise and then drop again, and it barely catches in time to prevent a stall. If I continue to tease it this way I can usually get it to stall. I'm getting no CELs or anything, but I intermittently will get a P035x code (it seemed to rove. I've gotten cylinder 1, 4, 6, but not consistently.). I have chased those around by swapping coils, checking/cleaning the connectors, etc.
I am kind of thinking that these codes are a symptom of my idle issues, and not the actual problem. What could I have done wrong? Could it be a vac issue? I had basically the entire ECU harness and all the vac lines disconnected to do the job, but as far as I can tell everything has been reconnected to the correct locations. I did have an SCT tune done to remove the phasers in the ECU. I installed it and still have the issue, so for now I am on the stock tune just to eliminate any variables.
Could my tune be the issue? Is this how you would expect the engine to behave with locked out phasers and no corresponding ECU tune?
Elantra XD (2001-06) :: 2004 - Lurches / Hesitates When Comes To A Traffic Light
My Car when it comes to a traffic light, wants to lurch just a bit, as I sit waiting for the light to change, I don't know whether it will stall, and also the RPM wants to rev on its own a little when I first get into the car to start it, and also while I am waiting at stoplights.

I have a 1986 Volvo 240. It has a button to push on the stick shift to put it in 5th gear. It drives and works fine except when I downshift from 5th gear. ..then it seems confused and has a hard time getting back into gear, it kind of hesitates and lurches forward. It will not go into reverse after it has been in 5th gear until I turn off the ignition, and start it again.

If i have the radio volume up fairly high, it will keep cutting off for a few seconds then come back on. then cut off again etc....
I presume the amp is getting hot and causing this, am I right? And would I need another amp, or maybe there is a fan in the amp not working? Or am I not even close? Its pretty annoying when that good song comes on and it cuts out.
Its not the actual radio that cuts off, its the sound from the speakers.

Car is stock and I seem to be getting a lot of jerking when I am on and off of the throttle peddle. It feels like a combination of sloppy motor mounts and a throttle response issue. What may be causing this? I am willing to bet that the motor mounts are partly to blame but it seems that there is more going on here.

I just bought an '08 r32 a few days ago. '08 with 17k on the odometer.
At low speeds (parking lot or stop and go traffic), giving it light throttle, the car lurches as if someone was giving it throttle and letting go.
Is this what is known as the hiccup problem (fuel tank vent) or the mechatronics problem?

View 1 RepliesPassat (B6) :: Rough Idle / Lurches Forward At Stoplights And High Squeals Off The Throttle
I have searched a decent amount on this and it seems like there is a whole list of items that could cause these problems. The car is a 2008 Passat 2.0T with the tiptronic. It is the early 2008 so it still has the FSI motor. It only has 53k on it and literally just came out of warranty a month or two before this all started happening.
It all started with the CEL coming on and the went into limp mode. We shut it off and turned it back on, the car went into limp mode again but upon the 3rd restart the car started and ran just fine. Then for a few weeks we just had a CEL (I don't know what code it was because I never scanned it at the time). Now as of lately the car is have a terrible rough idle, and at stops it will start kinda shaking and lurching forward. Sometimes it will also have a noticeable misfire upon start up. Also after going at highway speeds for some time the car will start to produce a squealing noise when not producing boost.
A few days ago I scanned it and these codes came back:
P0110
P0101
P0102
P0104
P0108
P0171
The first 5 IIRC are related to misfires and the P0171 is a lean code.
At first I thought this was the PCV valve because I had read about the lurching and the squeal that someone else had from that but after reading up more on things I am worried the P0171 is from the cam follower.
At this point I am just very tired of hearing my wife constantly complaining about the car. I want to try and figure this out without throwing part after part at it. I can't afford to buy items just to find out they aren't fixing it.
Ford Transmission :: 4R100 Hesitates Until Throttle Up To 1500 RPM Or So
I have a 2000 F350 7.3 with 308657 miles on it. After changing the trans fluid, filter and checking the center support bolts for proper torque I'm still having the same problem as before. When put in drive it doesn't seem to want to pull itself much until I throttle up to 1500rpm or so, then it grabs and goes. It acts similar in reverse but the rpms aren't as high. There was a coating of something inside the pan and on most of the parts along with the magnet being covered. What to look at to narrow down my problem?
View 4 RepliesPassat (B6) :: Tiptronic Modes Cuts Throttle?
I was driving in tip yesterday and some of time that 3-2 downshift is choppy b/c revs dont match. So i tried a modified heel-toe, timing it so that i pressed the gas while the engine was disengaged i got a little rpm boost but then nothing as if during the shift the throttle was cut. is this possibly a safety feature to prevent unnecessary wear? or is it just not possible with a tip?
View 6 RepliesFord Ranger / B-Series :: 1998 - Cuts Out While Driving - Throttle Position Sensor
The Problem: When I start my Ranger it dies right away, I do this about 10 times or so (worse when it is wet or has rained) then I can finally keep it running, by hitting the gas. Once I get it running it will cut out while driving as well. The idle is normal and if fires properly, I just took it in to the shop (non-dealer) and they said it fires normal and has normal fuel pressure, and the their computer returned no error codes. Their sugestion was replace the throttle position sensor. Do you all think this part could be the cause and where is the this sensor and is it hard to replace?

This truck isn't mine but it's an 05 F250 automatic. We just did oil cooler, STC, standpipes, dummy plugs, EGR delete, and cleaned the turbo. Truck starts perfectly and runs great 99% of the time. But after a high load throttle situation right when you let off the throttle the engine sounds and feels like it cuts out for a split second, then it comes back and everything is fine. It does it with stock tunes but it is more noticeable with his SCT tunes loaded. There are no codes being set. The weird thing is if your drive it relatively easily it never does it, and it never does it while it is actually under high load, at WOT it pulls like crazy until you let off a bit and then it happens.. It also doesn't do it every time but it is fairly often. It has edge insight with fuel pressure monitoring added, ICP doesn't drop out and neither does fuel pressure. What could cause it to do that?

Recently bought a 2006 RX400h - my first Lexus. Occasionally when braking it feels like the electric motors "won't release" for a second or two and the car lurches. Eventually they do and then braking feels normal. But while this is happening it feels like I have to really step on the brakes to get it to stop.

View 2 RepliesPrius (Gen 2) :: How Many Miles And / Or Gallons In Last Blip For Gas Level
How many miles and/or gallons are available when one is down to the last "blip" of the 10 blips showing the gas level?
I have gotten anywhere from 79 to 92 miles in the highest blip. I have gotten 43-50 miles on the second to last blip. Today I got 30 miles out of the last blip and it took a hair over 9 gallons to fill up the tank. I feared that I was cutting it pretty close.
I was just wondering how many miles I might expect to get out of that last blip. My normal MPG is 42-47 MPG. But the MPG really seems to go down as one gets towards the lower blips. Is there some kind of warning when one gets really low?
Spider - Alfaromeo :: 1990 - Blip At Idle / Engine Would Sometimes Stall While Driving
I have a 1990 Alfa spider. It has a blip at idle. Originally it was much worse. Idle would drop to 500 then pop up to 1200 the back down, back up etc. Engine would sometimes stall while driving. This happened as I would take my foot off the gas coming to a stop. I replaced the first large air duct between the mass air flow gauge and the air intake chamber(cracked on underside). Worked but still had blip which was then unpredictable. I cleaned the air flow gauge and the constant idle actuator with air flow cleaner. This worked more but I still have the blip during engine warmup. Idles fine at start up, blips for a while, then stops bliping as engine nears running temperature. What should I do next?
