Ford Ranger / B-Series :: 1994 V6 Rough Idle And Lost Fair Amount Of Power

I have a 94 Ford Ranger 4x4 4.0 V6. It has developed a rough idle and has lost i fair amount of power. I cleaned the maf sensor and iac valve. Along with replacing an o2 sensor that was reading bad, with no improvement. The guys at O'reilly took a look and think I may be dealing with a timing issue or a warped valve. My question here is to found the culprit? I'm very inexperienced at working on vehicles and am damn intimidated by the scale of a project like timing. I should add that while traveling on the highway in high gear at low rpms, it develops a rough stutter. I can either power through it or ease off to get it to stop, but it resumes shortly after. It almost acts like an egr valve stuck open when on the highway. But that doesn't account for the rough (a consistent put, put, put...) idle.

Golf VI R :: Scraping, Metal On Metal Sound That Diminished A Fair Amount When Brakes Were Warm

I picked my R up three weeks ago tomorrow. I took it in this morning because there has been brake noise from day one. The noise was a scraping, metal on metal sound that diminished a fair amount when the brakes were warm. I only got a very brief conversation with the service agent at the dealership this afternoon, and all he told me is that they had to order in new brakes. I don't know if it's just pads, or calipers or rotors or the whole deal! I'll get the whole scoop tomorrow.

Ford F-150 (2004-2008) :: 2006 - Rough Idle / Throttle Plate Had Lot Of Carbon

I recently bought a 2006 that idles rough, not real bad, but bad enough for me (and my 9 year old kid!) to notice. I asked the dealer where I bought it and they put it on the computer and said everything checked out. He said "it's a characteristic of this motor." I've never heard of such a thing. The truck has 27,000 miles on it and the dealer flushed the fuel system. He said the throttle plate had a lot of carbon on it, but it still idles rough... 4.6 idle rough?

Toyota - Corolla :: Revving The Engine Slightly Causes Smoke From Exhaust Pipe

I have a 2001 toyota corolla with a manual transmission that I just bought that has about 130,000 miles on it. It runs very well except for it runs out of oil about every 150 to 200 miles. The car does not seem to be leaking oil, however revving the engine in the slightest causes the car to smoke from the exhaust pipe. We tried changing the oil as well as putting in high mileage oil and sea foam motor treatment. This worked slightly but not much.

Ford Exhaust :: Crack And Subsequent Leak In Exhaust Pipe

Actually developed a crack and subsequent leak in a pipe running lengthwise, so assume the factory weld over the years went bad. Since it would be a weld overhead, wonder what method would be best? Would oxy acetylene work or mig? I don't have a tig so that not an option for me.

Volvo :: 760 Turbo Will Not Idle Properly - Rough Between 55 And 70

760 turbo intercooler 2.3 4-speed auto. It will not idle properly but when you run it around town it is fine, smooth and powerful. If you take it out on the motorway it will be ok for speeds up to 55 (lumpy going uphill) if you push it over 70 it is ok, but between 55 and 70 it is rough and sort of misses without backfiring. Also a cloud of black smoke comes out of the exhaust. If you kick it down to 3rd it will go like a rocket and not miss at all!! It has been seen by the RAC and been in the garage and they say everything is working, but can't check the air flowmeter as it would cost too much to buy one and it works fine.

Camry :: 2004 - Huge Amount Of White Smoke Came Out Of Exhaust

I have a 2004 Camry that I purchased used 8/2006 with 20,400 miles on it. It now has 83,000 miles on it. I’ve changed the oil and filter every 3,000 miles, and I’ve never had to add oil between changes. I’ve also replaced the antifreeze on time, using 5 yr/150,000 mile antifreeze. The only time I’ve had to add antifreeze was 4/23/13, to top off the overflow reservoir. Saturday I did my annual tune-up (plugs, air filter and fuel injector cleaner added to the gas). Plugs looked normal. Last week the car sat for several days, no issue on start-up.

Yesterday afternoon I started the car after it sat for two days. A huge amount of white smoke came out of the exhaust. It ran fine. I mentioned this to my wife, she said that about two weeks ago she saw a lot of black smoke (she thinks black) when she started the car and that it ran rough for about the first 4 miles and then started running ok. It has the 2AZFE engine, and I’ve read a TSB (TSB 1507) “It has been reported that stripped head bolt threads have been found on some of these engines during tear down. When the two rear head bolts lose their clamping ability they allow coolant to seep out at the rear of the cylinder head.” Could that be the problem?

Ford Super Duty (1999-2016) :: P0420 Code - Leak At The Joint Where Exhaust Manifold Meets Pipe Beside The Engine

I have a 2011 F350 CC long box 4x4, with a 6.2, 93,000 km on it. I periodically get a P0420. I clear it and sometimes it comes back in 10 or 20 KM and sometimes it comes back in a couple hundred km. Been doing this for about 800 KM.

Yesterday I got an exaust leak at the joint where the exaust manifold meets the pipe beside the engine. Checked close, bolts appear intact, leak is on the outboard side blowing towards the frame. Looks like a gasket or donut seal failed.

I am wondering if the catalytic converter was plugged or restrictive, would this cause the P0420 and could back pressure from a restricted catalyitic converter cause the gasket to blow?

Volvo :: 1994 - Rough Idle When Cold / Have To Pump Gas Pedal To Keep It Going

I have a 1994 Volvo 940 and have previously owned a 740 for many years. I've only owned this car for about 1 month. The car appears to have been well cared for. Doesn't leak a drop of any fluids, everything works, and mostly a really nice old car. What happens is that it idles rough when it's cold. In fact, I have to pump the gas pedal to keep it going. When I first start off, the performance is less than what it should be too. Once it get warm, it mostly runs fine.

I have so far replaced, the Plugs, Wires, Cap & Rotor. All the vacuum lines, crank position sensor, Air Mass Meter and the fuel filter and most all the fuel lines too. The Fuel Pump Relay was replaced but I removed it and saw a few cold solders and fixed those but no changes in performance. Before I replaced the Air Mass Meter I brought it to local shop and they returned a readout of 2-3-2 which I'm understanding means running too lean. That's why I replaced the Air Mass Meter. (I did notice a big improvement once I replaced the Air Mass Meter too.) It was interesting that when I replaced the Distributor Cap, I noticed like black carbon in there and I'm not sure what could cause that. Although, I did find the previous plugs were not all the same. Three of them were high spark performance plugs and one was just normal

I pulled the Idle Air Control Valve and plugged one side to ground and the other side to 12V and noticed the flapper moving when powered on/off. The previous owner told me he replaced both fuel pumps about two years ago. It also looks like the fuel regulator valve is mostly new.

I'm guessing now that I have a problem with the Idle Air Control Valve or perhaps the Fuel Temp Sensor under the intake manifold. I purchased the Fuel Temp Sensor and just have not installed it yet. I really don't want to remove the intake manifold but I know it's not going to be that bad. I know that it could be carbon build up on the intake valves but I'm not quite convinced yet. I put some fuel cleaner in the tank to see if that works and so far nothing yet. The car only has 150K on it and I was told that during the owner before me did do highway driving.

When it's warm, the car does run very very well. The idle is still a bit quirky even when warm. For instance, when I power on the A/C, the idle RPM doesn't increase like I expect that it should. (It did on my 740) ... I'm still thinking maybe it's the Idle Air Control Valve too. Perhaps it's intermittent or do I understand that they can gradually open and gradually close?
