IS F (2008-2014) :: Check VSC Light Comes On Randomly Which Sets Off Check Engine Light

Just had my lexus dealership do the ELF recall. While it was in there I had them check to see why my check vsc light comes on randomly which sets off the check engine light.

They came back and told me that my water pump is leaking, what are the future problems of a leaking water pump?

They said the check vsc light is coming on, in their words is "found center y pipe, gaskets leaking at front pipe, may still need to replace converter pipe." So what does that mean and what do I need to do?

Ford - Focus :: 2001 ZX3 Randomly Stalling But No Check Engine Light

I have a 2001 Ford Focus ZX3 (2D Hatchback) that has been randomly stalling since we bought it. There is no engine light, the dealership couldn't get it to stall and just gave it back. Another garage got it to stall and thought it might be the "idle-oxygen sensor" (not sure if I'm remembering the name correctly), but that didn't stop it from stalling either.

My wife is ready to dump it, but even spending a couple thousand a year on repairs is less than the grand total of a year's payments on a new car, insurance, etc. But it would be nice to fix it.

Ford Ranger / B-Series :: Check Engine Light Randomly Coming On

Ive got a '94 ranger with the 8 plugs and more often than not while driving and sometimes when it first starts, the cel comes on and immediately I notice a lil rough running and lack of power. Also my milage has dropped since this has started. Plugs, wires, o2 sensors, not to familiar with my gas saver. I love it cause I can just get in it and go. With twice the fuel milage as my bi truck!

Ford Escape / Hybrid :: 2010 - Check Engine Light Came On / Randomly Went Off While Idling

So my wife was driving our '10 escape xlt and the engine light came on and it displayed the 'check engine' message on the screen. It has 86500 miles and luckily no problems yet. The only thing that has changed was she accidentally put super premium gas in it the other day. The light came on and after she drove it home (about 10-12 miles) and it sat for a few hours and i drove it about 20 miles it randomly went off while it was idling.

I shut it off and let it sit for 20 minutes and then let it idle for a few and it never came back. It has been running ok. We definitely drive it a lot as she works day shift and i work nights. I'm just trying to make sure there's nothing wrong with it. I got a bulletin a while back about the intake getting moisture in it. I didn't know if maybe this could be the beginning of this or something else. This is a whole new territory for me as i consider my 91 f250 'new'

Lexus IS 2014+ :: JoeZ Axle Back - Check Engine Light Turn On But Going Off Randomly

So after installing my JoeZ axle back for about 5k miles I noticed there was an issue. The check engine light was going on but turning off randomly. I finally decided to take the car to the dealer for them to check out. So what the dealer said is that the JoeZ exhaust "direct bolt-on bolts" restricted flexibility and caused leaks in the front cats. He said that the stock exhaust screws had the springs on it to allow flexibility when hitting dips/potholes. With that said, He recommended switching the front two gaskets and using the stock "spring screws."

I was wondering, encountered this problem with the bolts that came with the JoeZ axle back? I bought the JoeZ off a user here and it came with bolts, which i assumed came with the exhaust when it was purchased new. Not even sure if the bolts he gave me was correct, or if i just made the mistake of not using stock bolts.

Buick - Lesabre :: Check Engine Light On Randomly And Signs Point To A Computer Malfunction

'95 LeSabre, 250K, runs great. Check engine light on randomly and signs point to a computer malfunction causing the light to come on. Is it true that only a dealership can replace the computer, not an indy mechanic? How much for the repair? Will it run ok w/o a new computer?

Ford Ranger / B-Series :: 2000 - Check Engine Light Randomly Comes On And Causes Power Loss Sometimes

2000 Ranger 2wd 3.0 ... I bought my truck last summer for $1k from my neighbor, it has hit a deer so the grill is busted,front drivers fender bent up and bumper is bent all to heck. The old girl is rock solid reliable though and gets decent mileage with cruise heat and ac so I'm happy.

Anyways on to the point, I am having two big issues with it, the check engine light randomly comes on and causes it lose power sometimes at others you don't notice it. I have not been able to get codes read because it goes off every single time I go to someplace with a scanner. The light will usually go off if you floor it for a long stretch maf maybe?

The other issue is the transmission, I don't know for sure which tranny it is but the overdrive button does not work at all even though the fuses are good and when I drive down the highway second gear you have to let off for it to shift sometimes ( I've been leaning towards the valve body gasket for that) and lately it has started a horrible vibration kicking out of overdrive or just downshifting on hills etc.?

I forgot to mention it has 255k miles on it and I don't know the history besides the balljoint I replaced this week and radiator when I bought it.

Ford Super Duty (1999-2016) :: Check Engine Light Turns On Randomly And Goes Off After A Couple Of Seconds

I own a 2000 Ford F-250 5.4 Automatic. It tows my 5th wheel trailer very good. On our last trip it suddenly experienced the "check engine light" effect.

The light turns on randomly and either goes of after a couple of seconds or it doesn't go on when I restart the engine.It is mainly annoying, but when in towing it really hurts, because the engine switches into an emergency mode and stalls.

I read that the engine uses only 4 cylinders. I read many articles on the web about that light, but I couldn't find a solution. The thing is I brought the car to several repair shops but none read a code from the computer.

I think it's not a real fault but a misreading or maybe a cable that's grounding? The problem is, I can't bring the car to a repair shop, because there is nothing wrong with the car. How can I find the source of the problem?

Passat (B5) :: Engine Light Beeping Randomly

The light in my wife's 03 Passat keeps coming on and beeping...the car will not "act up" when we take it to the dealership ( under warranty ) and they claim to have cleaned the O2 sensors. It never fails, she drives it home from the dealership and the CEL comes on and beeps a few times once she has driven about 10 minutes. Car runs great, but we don't know if it's hurting gas mileage.

Accent MC (2006-11) :: Squealing Noise Coming From Engine / Car Shakes At Higher Speeds

So I just got a bunch of work done on my car: the timing belt, spark plugs, serpentine belt and water pump were just replaced. I had the oil changed, the fluids changed, new front tires, and an alignment all about a month ago, but now every time i turn my car on there is a squealing noise coming from my engine (i assume a belt). Then when i get to higher speeds the entire car shakes, but more so on the drivers side. I have also noticed my brakes just starting to squeal as well, but the shaking was occurring before that. What it might be?

GMC :: 2010 - Knocking Sound And Check Engine Light Came On

I bought a used 2010 GMC Terrain with 28,000 miles on it in April of 2013. Two weeks after I purchased the car I heard a knocking sound and the check engine light came on. Took it to Dealer and they said the car is low on oil. They put in oil. Two weeks later check engine light comes back on. They put it through a test for oil consumption and that they said the car is using an excessive amount of oil. So they had to change out all of the pistons. One month later the check engine light comes back on.

Dealer calls GM and they say to reset computer....... three weeks later check engine light comes back on....... GM now says to dealer it needs a new engine computer. Not an hour after I pick the car up from it lastest stay at the dealer the light comes back on. GM doesn't know what it is. The mechanic at the dealer is awesome he did some research and thinks the problem is the gas. I now need to put in 90 or above so the engine won't knock. Not happy right now I didn't think that I would have to put in a high octane gas when I bought the car. Terrain owners do you have to put in a high octane gas?

Volvo :: 2007 - Rattle Sound / Check Engine Light Came On

I have a 2007 XC90 3.2 RWD with around 112,800 miles.

On acceleration, there is a rattle (not a valve knocking) that gets quieter once a steady cruise is achieved. At idle in gear, a very quiet rattle can be heard. When transmission is slipped into neutral, the rattle goes away. The engine shifts normally, accelerates normally and gas mileage is steady at around 20.5 mpg (mixed city and highway). I am using 93 octane gas. This week the check engine light came on.

Silverado :: Check Engine Light On / Sound Skips On The Radio

First of all, its 5.7L V8, it's been very well maintained, I've had my fair share of problems but nothing that has been that serious, except for the "check engine" light for the O2 sensor.

For about the last 4 months i've had the problem of the truck sometimes jerking while on the road. Once i started to speed up it seemed to not speed up which when it did, it jerked a bit. That was in the beginning.

AS OF NOW, the jerking has stopped but every now and then when i pull out of the garage and start to turn onto road it turns off, but all the status lights are left on. & when turn the key to turn it off and restart it starts again every time. Ive noticed that i was better off with the "check engine" light on then now because every time it is off it has these problems.

Also, when I barely start to tap the brake, again not all the time, sound skips on the radio. & this always happens when i tap on the brake & this happens more frequently when the "check engine" light is off.

Lexus ES 2007-12 :: Check Engine Light Came On / Low Hissing Sound

Was driving back home and the check engine light came on, these are the codes I got:

P0345: Camshaft Position Sensor "A" Circuit (Bank 2)
P0365: Camshaft Position Sensor "B" Circuit (Bank 1)
P0390: Camshaft Position Sensor "B" Circuit

The car drove fine, didn't feel any power loss, I heard a very very low hissing sound but I honestly don't even know if it was always there or not... I did put some gas from a different station for once, so I doubt the fuel caused this?
