Golf IV / Jetta IV :: Different Boost Pressure When Idle And Driving?
I bought my GTI used and don't know what software its running but I have some questions about the boost pressure. When I'm in Idle the car will only boost to about 7-10psi when i rev the engine in neutral, But when I'm driving it will boost all the way to about 17-20psi if I really stomp it, 15psi if I'm just giving it a bit of "go". The car takes off and goes really quick, seems like it has a lot of power so I doubt there's a boost leak but I'm wondering does the car boost differently in Idle because it knows its not moving?
View 2 RepliesGolf IV R32 :: Turbo - Misfire Under Boost / 1k RPM Idle (high)
Car started to do some weird stuff today. Misfiring under high load, as I get into boost.
Idle is around 1000-1100 RPMs. Cold start is fine, idle is normal in terms of going higher a bit, but then it sits at 1kish. This started last night after the car sat for a couple hours. Totally normal running and driving prior to this.
I've seen all the MKV threads about it that suggest everything from battery, to alternator, to grounds, to vacuum leaks, to intake leaks, to MAF.
Golf IV / Jetta IV :: Multiple Random Misfires In All 4 Cylinders Came Up / Idle And Boost
I have a mk4 1.8t Gti. Recently I have been having issues with idle and boost. I read the codes and multiple random misfires in all 4 cylinders came up, idle control and the crank, knock, and o2 sensor came up. Shows that system is running to lean as well. I changed the spark plugs and wires, check the coil packs they where done about 1k miles so I expect them to be perfectly fine. When I clear the codes it idles below 9-8k rpms. I also noticed the breather hose coming out of the valve cover into the EGT has a hole melted into it, could this cause any of my issues?

So after several thousand miles and many many moons of driving the R with my wife's wheelchair in the back, I find it way to bouncy for me. Still haven't put coilovers on due to this problem, I wasn't sure which c/o's would take the extra, say 300 pounds, on them as my DD. H&R RSS club sports are what I'm almost positive I'm getting seeing as they say keep those on the track, I'm sure they must be fairly sturdy. Now just a matter of time and saving money on top of health care for the wife which we won't go into. Now of course I'll put those on and then also their sway bars, front and rear along with someone's camber kit.

Recently I have noticed my psi reading on my tuner hovers around .25 to .35 in the morning right when I start my truck. Normally it reads zero or is in the negatives. After driving around and stopping at red lights it will hover between .80 and 1.25. Now, I know that not a lot but its not what it normally reads.
Last week I went off road and my exhaust took a hit and loosened up and caused a small leak near the rear axle. I unbolted it and for the most part fixed the leak minus some alit air flow coming from the slits in the pipe. I'm not getting any codes and haven't noticed any decrease in performance. It does however seam to slow down quicker when I let off the throttle. I'm running an SCT X4 with dpf and erg delete and have a S&B CAI.
I called a performance exhaust shop and the tech said a small leak shouldn't cause any issue like that especially because its so far back. Another respectable vendor told me it might be that my vein are stick.
Ford 6.0L Power Stroke Diesel :: Boost Read At Idle?
My question may be unique -- I cannot find anything about this -- at an idle, what should the boost read? Sunday at WOT I saw 28.76 -- but at idle it generally reads 0.1-0.4 -- bounces around a little -- but is that about right? Also, at WOT and 28+ boost what should the VGT read? I really am trying to sort out what this information is telling me -- not is that normal or average but what is ideal and what represents a red flag -- cut the truck off you have a problem kind of numbers.

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 just installed BC BR type coilovers on my 2010 Toyota Corolla S and now even driving at 55 on a smooth highway my car is a bit bouncy. Its really bouncy if I hit a dip or hole. The dampening setting is still at factory setting which is 8 clicks from full hard. I haven't lowered the car anymore than just putting the coilovers on so its about .5-1 inch lower than stock I would say.

The ride is okay until I reach concrete (grey colored) pavement on a highway going at highway speeds. Then it gets very bouncy, where even the st wheel vibrates. I can even hear some kind of noise coming from the back as it's bouncing on the highway. As soon as the pavement changes, this stops and it goes back to a comfortable ride. I also have some weird intermittent crunching type of noise that I hear while turning. But that is rare. There are about 700 miles on this car now.
View 12 RepliesHonda - Accord :: Suspension Bouncy / Car Leans A Lot When Going Around Corners
I have a 2003 Honda Accord V6. It has about 105K miles. The suspension seems a little bouncy. I would like better handling. The car leans a lot when going around corners. I've heard that new Honda struts are not as good for handling as some other brands.
I read that I should replace the dampers and springs together to get better handling. Most of the struts I've read about lower the car, however, I don't really want to lower it. I just want better handling for everyday driving. Am I on the right track?

I bought my wife a new 2014 Azera and we like it a lot but it seems to have a bounce at low speeds 0-20 mph, mainly when starting driving. It might seem to be a tire flat spot, but she only has 1,100 miles so far and it has always been there.

I installed lowering springs (1.5 inches front and rear) on my car, 1990 Maxima, with new performance shocks, but the ride is a little bouncy at times. I know this is from the reduced travel the shocks have..even though they are stiffer than stock. Is there any way to give a little more travel? or how to give the shocks more dampening force? (besides putting the old springs on of course). Would lighter wheels/tires work? How about loosening the center nut on the strut a bit?

Maybe it's because I've been away for two weeks and out of the RC, but when I drove for the first time in a while the car seems like it's noticeably bouncy on relatively smooth roads.
Again it could be my break from driving it. I mostly drive on Sport+ mode.

I've purchased my 2006 Sonata (LX) 2 years ago and noticed a very bouncy feeling when I drive. When I hit potholes and bumps I can feel the impact on the lower body, and when turning, hitting a bump would pull the car slightly in one direction. I've read through the forums that this might be normal (?) for 2006 Sonata's? I wanted to make sure if this is common occurrence and if changing the struts would make any difference. Here are pictures of my front and rear struts......
