1997 escort lx wagon, manual, 173,000 miles... When I stop at a red light or stop sign, it takes 10-15 seconds for the idle to drop down to where it should be, and when I push clutch in to shift gears it doesn't drop down, it stays where it is. No codes are coming up. I'm thinking IAC....

The ignition switch was changed since there was a recall for it. What is wrong with my car?

So over the last few months I have been having more and more idling and power loss issues with my 2006 V6. When idling she intermittently will try to stall and the rpms will drop below 500 and then spike back up. A large percentage of the time I hear a loud whining sound while driving down the road and I notice that turning off the air conditioner will remove the sound at times.
***what I have done so far**
Idler Pulley
Belt tensioner
sepentine belt
cleaned MAF
Cleaned Throttle body
Throttle Position Sensor
Had car reprogrammed
So I pulled the belt off and checked all the pulleys and did notice some grittiness in the AC pulley (inner) and was wondering if this might be the issue. Attached is a video I uploaded, Video .....

my 1990 Nissan 300zx with 136,000 miles often surges at highway speeds for several seconds then drops back down to normal. the surge is usually 1000 rpm. does not happen if not in overdrive, and will not happen unless having been driving for 15 minutes or so. also seems to occur more on hot days (80 degree +) than on cool days. mechanic has looked at this several times but not yet able to determine why.

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 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.
Prius (Gen 3) Fuel :: Sudden MPG Drop From 54 To 41
So yesterday, I reset my trip meter when I put on gas. I did a 7 mile drive home (no highways) MPG was around 54. This morning, my husband pulls the car from the garage to the driveway to install my name plates. When I start the car, I noticed MPG was 41. What could have caused the sudden overnight shift from 54 to 41. I only drove 3 miles to work since then so it is hovering around 42. Could the cold morning start to back up from garage did something? Could he have left the power switch on (and it shut off automatically).

Our 2012 Tiguan (FWD) has been experiencing a sudden drop in MPG for the past two weeks. We had no significant change in climate or driving habits. With mixed driving, we dropped from about 24 MPG to 20 MPG. We had our 40K service done just two weeks ago.

I have an 08 2.0T and it just suddenly had a huge drop in gas mileage. I recently had new tires put on and an oil change (about 35k miles). getting closer to 40k miles now and wondering what could be causing this. Usually I get about 30-33 mpg easy on the highway. Now I'm getting 24-26 mpg. Already checked the tire pressures. they're to spec. no gas leaks from what i can see.

I have a 2007 RX350, now at 110K miles, bought at 80K miles. I recently notice a sudden drop in mpg about 5K miles back (it might happen before that but I did not notice). Previously, the car gets around 25MPG on average, now it can only get 21 - 21.5 mpg, my range of a full tank drops around 60 miles. My route of driving everyday is pretty much the same. I have tried to change gas branch, using fuel system cleaner (Chevron Techron), check tire pressure but no luck.
What might be happening with the car that makes this significant drop in mpg?
I changed power steering rack and pinion at a dealer also about 5k miles back and at that point I had a dispute with a service consultant there. He made me drive back and forth a couple times without telling me that the part hadn't arrived yet (the car was on extended warranty). I then emailed directly to his boss. After that he treated me really well: gave me a most recent model loaner car for a week and did not charge for gas, and waived the deductible. Now I notice the MPG drop so I kind of link with this event and put him in doubt . Well, I'm not sure if he could do anything to the car since he's not the technician but still ... Can a guy put something to a car to reduce its fuel efficiency?
Prius (2010-12) Fuel :: Sudden Drop In Gas Mileage
I commuted to LA 2-3x a week. The mileage on my car is now at 90k. I have had an average of 40 mpg since new, but suddenly it began to drop. We took it to our local Toyota dealer and was told it was most likely a cable that needed to be cleaned. That was $160. It didn't work.
View 10 RepliesPrius Plug-in 2012-15 :: EV Mileage Sudden Drop
I was driving up a hill today at about 30 mph with .9 miles remaining showing on my EV battery meter when all of a sudden it drops to 0 EV miles remaining and shows only 2 of the battery level bars (which is very very low), and the engine of course turns on. What happened?
I promise I did not push the EV power bar over its threshold. I monitor that like a hawk. I also know for a fact that it jumped from .9 to 0, because I watch that part like a hawk. This part of the trip is near the end of my drive home and I've done it about 50 times so far with no issues. With .9 miles left at that point on the hill I have always been able to make it to my driveway with .4 or .5 remaining, so this is very odd.
Subaru - Forester :: 2004 - Gas Mileage Sudden Drop
I have a 2004 Subaru Forrester with a 2.5L engine (non-turbo) and about 137,000 miles. I usually get just a bit more than 300 miles on a tank of gas. About 3 weeks ago, I took the car for a major tune up (and they also replaced a valve cover around the spark plugs area). After the tune up, the car was running great and I was still getting about 300 miles to the tank. Within the last 10 days, I noticed that the gas mileage on the car has decreased - I am now getting closer to 250 miles per tank. The mechanic rechecked the fuel lines and test drove the car two days ago but did not see any signs of leaks. The weather was near freezing for about a week but has warmed up again to the 40's. My driving habits have not changed and I am driving the car the same way as before. I am stumped as to why the gas mileage would drop that much. What might be happening?
View 8 RepliesSanta FE SM (2001-06) :: 2003 - Sudden Drop In Gas Mileage
My 03 (129k miles, 2.7 AWD) is up to date on all maint (this summer saw new timing belt etc., transmission service) and oil is current. Spark plugs are due at 131k. Air filter is new, tire pressure maintained at 30-32psi.
MPG has consistently been ~20, slightly more on trips. October 27 to November 26 was 19.8 mpg. Putting on brand new snows (General Altimax Arctic) knocked it down to 17.5 mpg for the next ~250 miles. However, since early December it's dropped again to 13 mpg!
Mechanic just checked for brake drag (none - rotating one wheel turns all 3 others easily); no pulling, rolls well in Neutral. No engine symptoms (missing, bucking) or CEL lights. Power seems a little diminished (for instance, it takes longer to shift during acceleration sequence).
I will add my Lucas Oil gas treatment just in case it may be injectors. My mechanic says he has seen MPG suffer from certain gas brands (and I do wonder if the tank fillup after which the MPG dropped had something to do with it).
