Ford - Taurus :: RPMs Dropped Or Would Not Go Up To Normal - Thermostat Faulty

99 ford taurus 232000 miles. Great car I keep it fairly well maintained or my mechanic does actually. The thermostat was faulty and while in a long idle it shot all the way to HOT. The car did not over heat. the thermostat was replaced. A week later another long idle and it shot up to HOT again. A few days after that it was discovered I had a leak from the O rings going into the radiator part/section. They were replaced.

Yesterday I drove from work to the store about 25 miles. I got back to my car - started it up - it was rough/sluggish. I drove it 100 feet and noticed the RPM dropped or would not go up to where it had been normally. 40 to 45 miles an hour RPM at 1 or 1.5 .....It drove home "ok" but, I have had the car 13 years and I know there is something wrong. But I do not know what.

Toyota - Avalon :: Radiator Fluid Not Being Going Back Into Engine When It Cools

99 Toyota Avalon, 3.6 L engine, 160k milesThe engine sends radiator fluid to the overflow reservoir but doesn't suck it back into the engine when it cools.My mechanic replaced the radiator, cap, and hoses...no change. So. he put a chemical in the radiator fluid that is supposed to form a plug to stop a leak. After ~5 months of waiting, still no plug...no change. Tomorrow, I'm bring it back to him. If he says it needs a new head gasket, do you agree? If so, what would be a reasonable cost? Also, this timing belt has 68,000 miles on, do you think I should have him replace it, too (since he is doing work on the engine)?Do you think I am foolish to put the cost of repairs into this vehicle? The rest of the vehicle is good. We've had it since 2000 and have kept up with maintenance and services.

Mitsubishi - Triton :: 1998 - Coolant Won't Suck Back Into Radiator When Cools Down?

I have a 98 mitsubishi triton v6 3.0, I am confused with a issue I am having, coolant heats up and is put into reservoir tank as normal, but when car cools down it does not suck it back into radiator.

Have purchased new radiator cap.
No coolant on ground or any visible leaks in engine bay.
No white smoke when starting car or running
No sweet smell of coolant burning
No leaks inside heater
Car doesn't overheat, just pushes more coolant Into reservoir
Slight bubbles in radiator when cap off
No coolant in oil
Put a bottle of radiator leak fix in, no improvement,

Only thing is that 3 out of 5 intake manifold bolts are stuffed, they grab but don't get a tight fit, could this cause the vacuum leak not returning the coolant to radiator....

Ford - Explorer :: 1998 - Temp Gauge Shooting To High In Just Seconds Then Drops Back To Normal

For reasons I can't figure, the Temp gauge on the wife's Explorer is shooting from normal to high in just seconds. Then, it drops back to normal. When I looked at it this afternoon, I noted 2 things.

1) There was no sign of a coolant leak or overheating.

2) There wasn't ANY coolant in the tank!!!!!!!

The truck has evidently been running fine while this is going on.

Ford Super Duty (1999-2016) :: Erratic Steering For A Few Hundred Feet Sometimes And Then Goes Back To Normal

I have owned an 03 Excursion that I have had since last November that has started to feel like the steering is badly broken for a few hundred feet some times and then goes back to normal. It will do it some times after taking a corner and then suddenly there is a 1/4 turn play in the front and its wondering in the lane as I correct it back and forth and then it stops and goes back to normal. I've checked it and it all seems good and tight. The truck is stock height and has stock size wheels....

Ford Transmission :: 1993 E4OD - Trans Is Skipping Out Of Lockup For 1 - 2 Seconds And Then Goes Back To Normal Operation

Vehicle: 1994 TripleE RV based on Ford E350 7,3 Diesel, 70000 miles.

My trans is skipping out of lockup for 1-2 Seconds and then goes back to normal operation with lockup engaged. I am shure that it is the lockup disengaging because the increase in rpm is not as much as between gears.

This happens appr once or twice every hour when driving at normal constant highway speed. It happens both in 3rd and in OD. There is no flashing OD lamp, and the OD button is working (I use this actively when going up hill to keep up momentum and rpm)

I am not able to find out what causes this. I have replaced the speed sensor on the rear axle, the rpm sensor on the engine and the brake light switch on the brake pedal. Replaced one item at the time to be able to determine if any of these items was causing the problem. But none of them made any difference, the problem is still there. I have also inspected the harness connector on the trans and it seems fine to me.

Silverado :: Headlights Would Dim A Little Bit Then Go Back To Normal

2004 silverado, 2wd, V6, 150,000 miles on it. New plugs and wires 2 years ago. New fuel pump and fuel filter last summer. Truck was running fine but I did notice the last couple of mornings while I was driving the headlights would dim a little bit then go back to normal. Yesterday afternoon it started like it was 15 below out. Turned over kinda slow. But it wasn't that cold out. Anyway the headlights and dash lights were really dim. I got the truck in the driveway, revved the engine and they didn't get any brighter. The truck started running ruff and eventually quit. When I tried to restart it, it just clicked. When I turned the key off the dash lights got bright again.

Phaeton :: Temp Gauge Going Hot Then Back To Normal

So my understanding is the water temp gauge at 200 degrees is pretty much spot on. The last three days I notice the temp gauge go to 200 then up to 240 which is like just one line away from the red zone. I turned on my heat full blast and was on the tollway and the temps went back to 200. The moment I got back into stop and go traffic the temp goes up again 220-240 range. Again, one line away from the red zone. No other alarms or dash messages come up. No smell of anti-freeze.

As well, the oil temp which was always at 200 has done the same thing. Running over 200 in the 220 plus range. Could this just be low anti-freeze? If so, would I not get a dash warning light?

Golf IV R32 :: Startup Then Drops To Almost Dead And Goes Back Up To Normal Idle

So every morning I get in my car and start it up. Usually, It starts right up, hit 1.5K RPM and then drops to almost dead (~3-400RPM) and then goes back up to a normal idle. This has always concerned me but never thought too much of it since the car goes right back to normal after a few seconds. Today the car did the normal startup and then died. What is causing this?

Toyota - 4runner :: 1996 - Lose Power For 2 To 10 Second Then Go Back To Normal Acceleration

I have Toyota 4runner 1996 4 cylinder. it was running good (from time to time I would lose power for 2 to 10 second than it go back to normal acceleration). I had the check engine light on for almost 8 month. last week I took the car to mechanic shop for diagnosis. the mechanic changed the spark plugs and after that the engine lost power. the car cannot go over 30 or 35 mile per hour. He changed the spark plugs and put different ones, same thing he put the old ones back same problem, he changed the wires, the fuel filter, air filter, the distributor and rotor, but still the same problem. the problem is that the check engine light is off now and there no codes.

F Series :: 1998 F150 - Temperature Gauge Went Up Then Immediately Fell Back Down To Normal

I have a 98 f150(4.6 V8) that has 'seemingly' overheated for about 5 seconds twice in the last month. I noticed the temperature gauge went all the way up after about 1 mile of travel, then it immediately fell back down to normal. The truck has 198k miles.

I flushed out the system using a Peak Flushing Tee, replaced the thermostat with spring facing the engine block, and refilled the system.

I haven't had another overheating instance but I am having problems with my heater....the truck seems to warm up fine and the heat starts off working well. The temperature gauge reads normal for a few minutes then drops and I lose the heat. The truck blows cool air for a while, then will start blocking hot air again.

I believe the water pump has been replaced fairly recently...the pulley has no slack and I don't see any leaks or wetness around the pump or its weep-hole.

I read it could be a blend door or blend door actuator. I don't hear any funny clicking and obviously get some heat.

Should I try another new thermostat? Intermittent water pump problems?
