Had a tune-up and a mechanic also looked at the accelerator pedalfor some reason, but no report regarding the fuel injection or regulatory components which I suppose should have signaled an issue when the computer diagnostic was run if I am to understand the mechanic's position.
View 2 RepliesMy 4 cylinder Tacoma vibrates a lot when it is idling, especially sitting in "drive" at traffic lights. My regular mechanic has tried various things to remedy it but none has really worked. He suggested the valves may need to be adjusted. Is this plausible? Or is he off-base? And is it really expensive?
View 4 RepliesWe have a 1999 4Runner with the V6 engine, auto tranny, and 230k miles. For going on a year now the engine will occasionally stall when at idle…usually happening at stop lights. The engine starts right back up. This may occur once every other month or once a week for several weeks. Stalling has occurred with warm engine and cold engine, during raining/damp period and when dry. Never has the check engine light come on or has it generated fault codes. Dealer can’t find anything wrong. We’ve replaced Air Idle Control Sensor (OEM), Throttle Position Sensor, Mass Airflow Sensor, and cleaned the throttle body. Plug wires and timing belt were replaced a couple of years ago. Other than this one issue it runs great. What to try next.

I had my catalytic converter and flex pipe replaced this summer. Lately, my car has been idling rough. While stuck in some horrific stop and go traffic three weeks ago, it started to make noises as if it would stall out. It didn't, but it still sometimes makes those noises.
The car seems fine on the highway. No loss of power. I did think that the hood felt too warm on a recent trip, but the temperature gauge in the car showed no issue.
The car hesitated when I tried to start it last week, but normally starts fine. It was the first cold day of the year.
I saw some white smoke come out of the tailpipe last week. It only happened once. Coolant and oil levels are fine. The spark plugs look good.
The fill pipe has been leaking gas for several months. It leaks if the tank is more than half full and it drips a bit of gas when I fill up. Two mechanics have not been able to find the leak and have told me not to replace it until it is a problem, given the age of my car.
I took it to a mechanic today (not the one who replaced the cat). He told me that the rough idling is due to the new flex pipe being shorter than what was originally there. He assured me that the car is fine to drive long distances and that there was nothing wrong with it. There's no check engine light or anything on the dash to indicate a problem.
I should be relieved, but I'm not. I've lost confidence in my car. Can the stalling noises and rough idling be explained away by a changed exhaust system? Or are these signs of a problem about to happen?
I started having problems with my '99 Cirrus last month, it would randomly stall while driving or while in idle. With no check engine light or any other tell tale signs of a problem. I'm not entirely knowledgeable about how the entirety of the car's systems function, though I new I should check my fuel system. I wasn't getting any fuel to the engine whatsoever, so I replaced the fuel filter because when I got it off and looked at it it was clear it was bad. Then I put it all back together to try and run it and it continued to stall.
Thinking it must be the fuel pump at this point I dropped the fuel tank and replaced it. It ran for about 35 miles before the same problem started happening again. So I checked all the fuses, and relays and just to be safe replaced all the relays related to the fuel pump, and fuel system and i even replaced the auto shutdown relay. The car continued to have the same problem, so I did some research and found out it could be a dirty throttle body so I cleaned it even though it wasn't that dirty, and checked my air filter for how clean it was and it was clean. The car still continues to stall in idle and while driving.
I have a 1999 Toyota Tacoma pickup, 5 speed stick 4 cylinder. When I first start it up it runs at a lower idle than it should. But as soon as it warms up just a bit the idle goes to about 12-15K rpm. Also, when it sits during the day and it's warm outside it will start up with the fast idle.
I don't know if this is coincidence or not but, I found a rabbit sleeping under the hood during the winter (this has been going on for a while). The rabbit chewed through a vacuum hose and a spark plug wire. The vacuum hose was split right by the fitting so I just cut off the 1 1/2" of tubing and re-attached it. The spark plug wire I didn't know was damaged until I drove it for about 5 miles or so when I finally got out to see why it was still running bad. I then had to drive another 5 or so miles to the auto parts store to replace it. I have replaced all the spark plug wires just to be sure. What this would be?
My Tacoma makes very loud roaring and whistling noises mostly when I am idle and the brake is engaged while the clutch is depressed. Sometimes, she'll rear and balk continuously --- even more loudly --- depending on the outside temperature and her level of activity. I need to get her fixed, but live in the New York City area and am a broke graduate student terrified of getting ripped off. Do you think it's just belts? My transmission (sometimes I can feel the noise in my gear shifter)?
View 10 RepliesMy 2001 toyota camry is great but has an intermittent, annoying problem no one can diagnose or correct. If I drive for a while at top highway speed (say 65mph) and then have to come to a stop (to pay toll or stop light) I get a very rough idle and then the car stalls. Have had new plugs, wires, coil, radiator already done to solve problem. Check engine light never comes on. Can also drive lengthy trip and it doesn't happen.
View 18 RepliesMy 2007 with 73k has started to idle rough at traffic lights. Not horrible, but a noticeable vibration. Rpm's are around 500. If I put it in neutral, rmps go up to about 800 and idle gets better. What could cause a rough idle like this?
View 14 RepliesI fill my gas tank to 100% but I don't pump it again and overfill it like most people do after the pump stops. I then proceed to start the car. Initially it revs up and starts fine but when it revs back down to idle it does a rough idling (and sometimes it stalls). To get around the stall, I would restart and rev the engine to 3000 rpm for about 2 mins and it would be fine enough that I can drive away without it stalling but after a mile the rough idling stops and everything is back to normal. I replaced the PCV valve and it worked for about a year but it all came back again. I am stumped and every mechanic gives me a different reason and none of the reasons are even definite. It's one of those "lets try this and see what happens". One more thing, the car runs fine. It only happens when I pump more than 75% of the tank.
View 5 RepliesI have a 1999 Toyota Tacoma manual shift and when driving with the air conditioning on my truck makes an odd noise. The noise is very sporatic but seems to happen most at about 50MPH and 70MPH. I am going to try and type out the sound...."Chht" It is quick and only happens once at a time. The power of the engine drops when it happens as though it may cut out. But it is very quick.
View 1 RepliesA couple of days ago I removed the key from my 1999 Toyota Tacoma (175,000 mies)and the power stayed on. Specifically, the ignition was in the proper "Lock" position when the key was removed, but the radio continued to play and the dash clock stayed lit.
Normally, prior to this change, the radio turns off with the ignition being rotated to "Lock" and the clock LED turns off. There hasn't been any abnormal force applied to the ignition. As well, I haven't noticed any other electrical issues, but it still is operating in this abnormal way.
After 175,000 miles worth of starts has my ignition switch worn to the point of "shorting on"?
I have a 1999 Toyota Tacoma 4X4 pickup that is running terrible at any RPM under 1800. It is also bad under acceleration at any RPM, or when the a/c is on. The truck is showing no problem codes at all. I have been throwing parts at it with no success. I have replaced in order - the air cleaner, fuel filter, fuel pressure regulator, fuel pump, and even the timing belt.
View 2 RepliesMy Brother-in-law recently lent us his 1995 Toyota Sienna which had 196,000 miles. After returning it, he asked if we had any problems with it. We questioned why he thought we would have and he said that the vehicle was stalling at various times when the idle was low - i.e. at a stop light etc. This happened intermittently and his mechanic could not diagnose the issue. Other than this, the vehicle operates fine.
View 5 RepliesI have a 1985 Toyota Tercel that I just got, the thing has been sitting for 2 years and it started before it was left to sit. Now I have done all the usual maintenance on it, replaced the sparks, oil, oil filter, air filter, distributor cap, fuel pump and fuel filter, gave it some gas treatment and filled the tank and some carb cleaner to clean out the gunked up carb. My problem is that it starts but dies right after when it tries to idle. it can shift in to gear and such but it will still die out right after about 10 seconds unless I keep tapping the gas. The more times I start it the longer it stays idle but I wonder what the problem is...
View 4 RepliesA few months ago I bought a used 2007 Mercedes C280. Overall, I've been very happy with the car. The first month or so was heavy on longer highway driving, and it seemed to be getting decent gas mileage. The last couple of months have been mostly short range city driving, and the mileage seems significantly less. I wonder about the idle speed, on the assumption that it may be wasting a lot of gas sitting at stop lights and in traffic. The tachometer reading isn't always consistent at idle, but fairly often it's up close to 9,000 rpm. What should I be seeing, and does this need attention?
View 6 RepliesA couple of years ago I began to hear a high-pitched, metallic, chirping/chittering/rustling noise - sort of like tiny birds or insects - coming from somewhere behind me in my 1999 Toyota Tacoma pickup. The sound would only occur at speeds between about 30 and 55 mph, and would become louder after a long period of driving.
Pressing down the accelerator would bring it on, but it would be loudest and chirpiest during the act of letting up on the accelerator. Coasting down a mountain road with my foot off the gas after a long day of driving made it very loud!
I've had a couple of mechanics listen to it (one elderly car guy couldn't hear sounds that high-pitched) and have sat my brother in the back of the truck to try to figure out where it's coming from. The noise is still there, and can occur at lower speeds than formerly. In fact it's there pretty continuously above about 15 mph, but still varies with acceleration as above.
I have a 99 tacoma with a 3.4 L automatic with 160,000 miles. For the past year my truck will idle rough and quit after revving high. After driving around for a few min its fine until I accelerate hard and get it up to about 4 to 5 thousand rpms. I recently changed the timing belt and accidentally got it about two teeth off. While it was like that, it didnt have much power and it was very loud, but it didnt have the problem. Once I fixed it and got it timed right it started having the problem again.
View 1 RepliesMy 1999 Toyota Tacoma (Ext Cab, 4x4 TRD) has 162K miles and now the clutch pedal intermittently sticks to the floor. I have to pull it off the floor with my toes while driving and have also felt the pedal start to pull back towards the floor on its own while the truck is in gear.
I'm looking for some wisdom as a few blogs/websites point towards a master cylinder, others say the master and slave, and my local auto shop said I need to replace the entire clutch assembly and throttle bearing. My truck is no spring chicken anymore but I'd like to keep it running for a few more years...
I have a 1999 toyota tacoma 70,000/mi. While idling, at random intervals, truck surges forward. Have to stay on the brake. Cannot drive in winter. Took to Toyota dealer and other mechanics... described problem and that A/C seems to be on all the time. No one has been able to fix. My brother disconnected the A/C and surging has stopped, but I need a better fix that will allow my using AC.
View 4 RepliesI have a 2001 Toyota celica GT auto. It has 120k miles. I seem to have an issue that really is not causing a problem except for annoyance. After coming to a stop the car seems to exhibit the signs of stalling (car idles rough, shakes a bit) however the car never stalls. Once I start driving all is well. Now I took it to the dealer and they replaced the Idle Air Control Valve which is under the throttle body. They said it was getting stuck and due to the higher mileage possible. It was replaced and the problem is still there. The funny thing is even though the car exhibits these stalling symptoms the idle does not drop below 500 rpm (both dealer and I have verified this).
