Toyota - Corolla :: 1993 - Dash Lights Come On When Brakes Applied
My '93 Toyota Corolla recently had dash lights come on when I applied the brakes - after parking, gear shift placed in 'park', and ignition turned off. I have never noticed this before (btw, have new battery installed within past two weeks). Is this an indicator of anything I should pay attention to? It did this about a week and now has stopped.

Trying to track down an air conditioning problem. Seems like a vacuum leak somewhere is screwing with my AC and shutting it down upon giving it any throttle (hills etc). Where should I look first or is there a certain area that is prone to leaks?...truck is a stock 1993 F-350 460/auto.

I have a 93 Regal custom with 3800 engine. The engine idles at a stop at about 800 rpm. At times it will idle at 1000 rpm or maybe 1200 to 1500 rpm. When the idle is very high I will shut the engine and restart, most times it will return to 800 rpm. I cleaned the MAF and this seemed the frequency has lessened.

190000 miles... Driving on the highway my car began to vibrate and lose speed. I had to shift out of overdrive before I could get the car to respond again. It continued to feel incredibly impeded. I could not push the car over 65mph and couldn't remain at speed going uphill. From a dead stop, the car accelerates incredibly slow in any gear. The engine feels impeded even in P and N almost like the trans does not disengage.
The trans will downshift and kick up RPM when the pedal is put to the floor like normal. What could be causing the trouble and how much it could cost to have repaired? I have checked the trans fluid in park at op temp and it's perfect. No fluid is leaking from the car. Car feels like it's in drive and I'm holding the brakes while hitting the gas... even in P and N so I don't think it could be brakes.
Diesel - Brakes - Manual-transmissions - Cylinder - Mercedes-benz :: 1978 - Leak In Vacuum System?
When the brake pedal is first depressed, it sounds like air is being pushed out of it, sort of like flatulence, and are less responsive. When i pump the brake, it fills with air and tightens. The brakes work when I depress the pedal all the way down. Also, I have to pull my driver-side door shut a few times before it will close and lock with the vacuum system. Otherwise it won't close. Eventually the door closes and I can lock it when I shut the door just right. (My mechanic and I are working together to find replacement locks from junk yards) Is this the master cylinder? Or could this be due to a leak in the vacuum system since my door does not readily close? Or is it something else entirely? 1978 Mercedes 240D...

Car started fine but stalled on first brake application with the skid-control light illuminated, restarted fine but stalled again on next brake application (skid-control light stayed on). Decided to head for the dealer which was only a few blocks away, drove there knowing that it may stall when brakes were applied (engine would start, idle and operate when driving but the problem would only occur on brake application.... approx when the transmission would down shift to third or second gear). My last stop before turning into the dealer's parking lot, the engine quit and refused to restart.... finally came back to life after about 5mins and was able to complete my somewhat dangerous trip (whole journey was on very quiet back streets). At first I thought it could be related to the infamous brake switch but the service rep informed me that they couldn't communicate with any control module with the scan tool. Now I sit and wait, hopefully they will call with some good news soon.

I have a 1999 Buick Regal GS and it feels like I'm continuously riding the brakes at random times and engine sounds like its working harder than usual to get the car to move. I thought I had this problem solved by replacing the master cylinder but I seems to be happening again. The reason I replaced the master cylinder was because I came out one morning about 2 months ago and started down my driveway to get the mail (I live on a steep hill) and I thought I had a broken line or something because I had almost no pedal and it was sinking to the floor. What confused me the brakes seemed good the day before when I drove about 40 miles round trip to town and then parked it overnight. (except for the brakes sticking feeling) I had the car put on a rack and found nothing more than a slow leak at the proportioning valve but I noticed on the way to the shop the car was no longer hard to move and was smoother rolling than it had been in a long long time.
The brake fluid was a little low but when I filled it to the max level the pedal still felt soft and would sink unit I had the master cylinder replaced, With the sinking pedal and all I was thinking its probably a bad/sticking master cylinder that maybe could have been applying slight pressure to all the brakes at once and now it was released. I purchased a reman master cylinder from advance and had it put on and it seemed to work great and my car was still rolling freely. The proportional valve is still leaking (small drip when pressed) but I didn't think it could cause all these problems. I usually have to pump the brake before I leave of a morning or my pedal will be soft and sink but not all the time.
Recently I noticed my car is starting to feel like it is sticking again and my last mpg estimate was 17mpg, I might be a little hard on the throttle at times but not all the time. The rims feel equally warm after driving but not real hot. I have replaced a lot of parts over the last 2 years so most of the braking parts are near new. All the brake lines have been replaced along with the hydraulic hoses. Front calipers are new Rear caliper I rebuilt myself Master cylinder was replaced over a month ago. Could it be the abs unit or the brake booster? A week ago the car rolled freely but the pedal was starting to feel hard like the symptoms of a bad brake booster.
Camry :: 2009 - Idle Drop Engine / Car Shaking When Brakes Applied And AC Is On
Here are my issues.
1. In drive under load during braking especially when the AC is on the car shakes. I can put it in to neutral and it works but when in drive or reverse especially with AC the car shakes. (not just a little bit)
2. The RPMs are settling around 400-500 so the stuttering makes since.
3. Feels like everything effects my Idle RPM speed (breaks, steering, AC, power windows lol!)
I am thinking possible fixes from research
1. ECU Reset with everything on AC/Lights/ Im planning on mashing on the breaks 2 see if the extra power usage work.
2. Throttle Body cleaning
3. Alternator could be bad
Volvo :: Vacuum Leak - Check Engine Codes
Just bought my volvo several days ago. It was throwing check engine codes so I had it scanned and it came down to a vacuum leak. I found the spot where it was leaking which was a little piece to the left and slightly behind the exhaust manifold, slightly behind and beneath the thermostat housing. It went from a hard plastic vacuum line, to a 1.5 inch rubber vacuum line which plugged into a nipple on the exhaust manifold or something behind the manifold. the rubber section had 3 large holes in it, so i replaced it with more rubber vacuum line. same length and same inner diameter.
What I did notice when I replaced it was that it was too large for the plastic line, slid on way too easy, but i had to fight it onto the nipple. The check engine codes went away for 2 days(I drove about 150 miles over that time) but today, the check engine light came back on, went to auto zone, had them scan it, came back with vacuum leak. So when I got home, I popped the hood, sprayed some carb cleaner by the replacement vacuum job I did, and sure enough the idle changed. What the proper replacement hose is for that area?

Golf/GTI VI :: Random Engine Misfires All Day / Vacuum Leak
Car: 2011 VW GTI MkVI
Mileage: 79k
Configuration: Stock
Warranty/Coverage: None
So I started my car last Monday and the check engine light was on. Didn't think much of it because the car ran fine and there were no immediate symptoms. I was busy with work this week, but noticed some changes in the car's performance over time so I waited till Thursday to have it scanned at AutoZone, which threw the following codes:
P 300 Definition: Random Engine Misfire
Explanation: Lean air/fuel ratio
Probable Cause: Ignition system misfire condition, Fuel injector fault, Engine mechanical condition
P 302 Definition: Cylinder 2 Misfire
Explanation: Vacuum leak on engine
Probable Cause: Ignition system misfire condition, Fuel injector fault, Engine mechanical condition
P 303 Definition: Cylinder 3 Misfire
Explanation: Vacuum leak on engine
Probable Cause: Ignition system misfire condition, Fuel injector fault, Engine mechanical condition
Prior to making any purchases I noticed that I started losing some pickup, primarily in lower gears between 2-3k RPM's. Praying that it was somehow just the coils/plugs I bought the R8 pack for both and replaced them this evening. Engine starts up and continues to misfire. I have not had a chance to have it scanned but it would appear it isn't the plugs or coils.
When the plugs were removed, there was an 'oily' substance on the threads, which also seemed like it could have been burnt off fuel or oil pushed up from the cylinder. Also 2 of the plugs seemed looser than the others and didn't feel properly sealed. New R8 install included proper plugs for STOCK application, as I do not run any tuning, and i installed with the appropriate plug grease added lightly to the threads.
I took the car for a spin with the R8 coils/plugs installed to compare it to how the car was doing prior the install. Car misfires and seems fine (relatively) at idle and revving to 2-3k rpm yields NO change. It is almost unable to accelerate up a hill, or go past 30 MPH without the car shaking and any gear higher than 3rd seems not drivable. I feel these are my potential diagnoses before i bring it somewhere and have it looked at.
In Order of Most Likely:
1) Fuel Injectors
2) Air Intake
3) High Pressure Fuel Pump
4) Electronic Leads for the Coils
5) Battery Needs Changed
6) Chain Tensioner Failure
7) Coils and Sparks are all Bad, and I am an idiot
I would prefer to do this work myself and can afford the parts. I just didn't want to be fooling around all month without a mode of transportation to get to and from work.
Passat (B5) :: Check Engine Light Stays On Due To Vacuum Leak
I have a 2000 B5 . It has minor damage front and rear (cosmetic only). Also, the check engine light stays on due to a vacuum leak somewhere between the MAF and the intake manifold. It would need a full paint job at some point after the body work was completed.

I have just replaced my vacuum lines after find a hole in the hose going the the vacuum reservoir. I have also recently replace the pcv hose. This seems to have created increased vacuum pressure and I am now hearing a hissing coming from the back center part of the engine.
Pulling codes P1411, P1423, P1138
Regarding photo - The area the hissing appears to come from is located in the rectangle area, more or less.

Ford F-150 - 1997-2003 :: Vacuum Leak When Engine Is Under Load
It has been since the 80's that I have attempted to do any work on a vehicle. How do I find a vacuum leak and where is my vacuum canister. I am assuming that it is a vacuum leak for anytime my engine has a load on it the air stops coming out of the dash vents and goes to the defrost vents. I have an 2000 F150 with the large engine with about 112,000 miles.

1993 Buick Regal 3.1l V6 Multiport injection
Problem: The care currently has a hard start, and a fluctuating idle. I bought the car a year and a half ago it still has low miles about 94,000. The care used to start fine but had a fluctuating idle in the range of 750 to 2500 rpm. My brother who is a mechanic and doesn’t live near, do all the gaskets when he visited. Then the idle fluctuation dropped to 750 to 1000rpm, when the car rpms fluctuate there is a whirring sound I can hear from the cab, like a pump or pull system. On occasion there is a vibration as well but it is inconstant and irregular. Fuel pressure seems to fluctuate as well. If the car will not start I give it a little gas and it will run fine after a minute or two, but then the idle starts to fluctuate.
No fuse issues I can tell and relays seem to be fine.Checked for lose wiring connections found, none. I have replaced:
- Hoses and gaskets
- Starter motor
- Battery
- Fuel Pressure regulator
- Fuel Filter
- Spark plugs and wires
- TPS
- Idle Air control Valve
- Crank shaft sensor
- PCV.
Right now I’m thinking it could be the fuel pump (a nightmare to change on this car), a fuel injector failing, and the ignition switch.
Buick - Regal :: 1993 - Transverse Spring Isolator Pads Worn Off?
I have a 1993 Regal Custom. The friction pads on the transverse spring had worn off. I replaced with the aftermarket isolator pads. These work well. The problem I am having is that after a few months they tend to shoot out. You will hear a large bang and then see the pad shoot out in the rear view mirror. This seems to happen when their is a load in the rear of the car. What can be done to prevent this.

I recently had a Jasper rebuilt engine installed in my Ford E150. Since than my check engine light keeps coming on and the computer is saying my cas air mix is "lean".
