Could be a problem with the idle air control valve, or a vac leak.
Does it happen all the time or just after you have been driving ?

I have a 1997 Fiesta auto, runs fine apart from a slight gearbox issue. When starting from cold and selecting Drive the car will sit there for upto 5 seconds before moving away and will stall if the brakes...


I would be looking for a vacumn hose leaking. The cold engine needs a rich mixture and braking uses the vacumn booster causing the mixure to lean. A warm engine races with the extra air.

My Tundra 2000 4.7L V8 won't move fast, the engine stops whenever i try to press the turtle or accelerate in fact the engine starts very well even when the car is at pack but when i try to race or fire on...


Press the turtle? Could be many things, such as bad TPS, MAF, leak in hose between MAF and throttle body, vacuum leak, coolant temp sensor, bad catalytic converter or muffler. Any codes set?

Hi my Ford Fiesta suddenly stop while driving. There is red sign of like ship in meter and also meter is still showing race 50


...you mean this? Check your oil level. Does the car still run? If your oil is full and you're having problems with your warning lights and gauges you may need to have Ford look at it. All of those devices in that cluster are tied in together by a computer.

Gas pedal gets stuck and keeps the car going cant stop without turning the car off


dont drive it. find the cause and fix it now.
Hot and cold engine or BOTH>?
1995 Tracker, no tranny , no 4wd , on engine options stated.
Exact high RPM in neutral, not stated...... 1500 is normal cold.
keeps going in Neutral. (nah , you have 5 ways to stop any car.
key, hand brake, foot brake and neutral. and with 4wd, 1 more neutral.
keep that in mind driving any car.
this car has up to 3 throttle cables that can stick. and more!

1: floor mats hit the pedal>? ala. Toyota style (lawsuits)
2: the three cables are, throttle. , cruise and A/T transmission kick down cable. if car is M/T and no cruise it has 1 cable.
so disconnect it, throttle fixed? (disconn,. 1 by 1, bingo?

no cure?, then its not the pedal , you meant just high idle.
yes, replace the cable or bad parts three.
ok say its not the cables.. (tests proved that)
the 95 came with 2 engines, 8valves and 16valves,
they work differently (8v love so race, 16v loves to stall)

1: ISC Stuck open, common.
2: 8v, any air leaks at all , will cause super high idle speeds.
3: throttle valve in the throttle body is stuckopen (gunk) or the return spring broken (very very rare the latter,in fact never heard of one breaking)
4: IAC (thermal idle control stuck open ,(my 97 was). and lots more.
5: on the 16v it takes 2 failures. to make high idle.
gross rich running engine (cold engine its normal) and any air leak
once hot the engine can not race unless there is huge overfueling
and an air leak.
6: the 8v has this device on the side of the throttle body.
called a dash pot. its just a fast idle vacuum servo.
if stuck open the engine will scream full time....
7: ECU stuck in limphome, can cause too high idle speeds.

we need to know which engine
http://www.fixkick.com/find-parts.html
8v or 16v first.
then does the idle race hot or cold or both (engine temperatures)
if it races , then how fast?, RPM the dash tachometer tells you that.

it can be as simple as a 50cent hose cracked.
to a dead ISC. (idle speed control) IAC is thermal idle air controller.
the IAC must be closed on a hot engine,
if the the engine never gets hot,it will scream full time.

My 1975 motorhome dies at every stop sign,is this a sign of carburator problems


The engine is not getting enough air, maybe the air filter is very dirty or the idle is too low. In newer vehicles there is some thing called IAC idle air control valve which would bump up the RPM so the engine dosent die BUT in the older vehicles there is a choke which works with a butter fly which bumps up the race should there be extra load put on the engine, load is stopping, turning, A/C on or other loads on engine.

Hydraulic valve adjustment


The lifters are not supposed to be adjusted.
Each lifter is a small "engine" itself.
They are supposed to be self-adjusting (this was changed way back in the 1950's).
If you are determined to adjust them, you will need to contact a place that builds race car engines, because there are procedures race cars use that adjust them.
Oh yes, you can also replace hydraulic lifters with solid lifters.
Some race cars do, and that is because, at really high RPM's, lifters can :"float", causing the engine to "top out" and not go any faster. I had that happen on a car back in the 1970's.
Be blessed.

It wouldn't be a bad idea to have a transmission specialist to run a scan on the transmission...could be a bad converter.

2003 toyota avalon gets check engine light and goes when idleing


Take the car to a local Auto Parts Retailer, and have them check the fault codes on your on-board computer. Given the year of your car, it is probably an OBD-2 type computer. They can print out whatever the computer diagnostic says the problem is. I am going to guess the throttle position sensor is to blame since it sounds just like what my sister's Mazda Mommyvan was doing.
