Why does my Toyota Corolla hesitate when I accelerate?
In turn, the ECM will inject a lower fuel amount for the supposedly lower airflow in order to keep the air-fuel ratio, which in turn will end up being too lean. This will produce the hesitation or stalling you are experiencing. In the worst cases, it will include engine knocking. Toyota Corolla ECM/ECU replacement.
How can you tell if your car charger is in trouble?
Usually, the first sign that your charging system is in trouble is a “battery,” “ALT,” or “CHARGE” warning light illuminating on your instrument panel while driving. It means that for some reason, the alternator has stopped charging the battery and your car is running on battery power.
What kind of engine does a 2005 corolla have?
Ready to use and VIN programmed. Fits 2005, 2006 and 2007 Corolla CE, Corolla S and Corolla VE, 1.8L VVti Automatic, 1-year warranty
Where is the MAF sensor located in a corolla?
In the Corolla, it is very accessible and no mechanical experience is needed to do this. In the picture below, the location of the MAF sensor of 2004, 2005, 2006 and 2007 Corolla is shown (earlier or later models may also be in the same area). You will find it inside the engine compartment, installed somewhere in the air intake path.
Why does my car engine hesitate when I accelerate?
You may think that you are using in your car a very good air filter, so the MAF sensor could not be the problem, but the bad news is that Airflow sensors (MAF, MAFS or AFM) get contaminated by lots of microscopic debris that escape the air filter of the vehicle and accumulate over time on its sensing parts.
Can a car stall with a bad throttle position sensor?
The engine can stall for no reason and without any warning. This happens when the TPS gives incorrect information to the ECM. The engine can stall at high speed, at low speed, or even at idle. A faulty throttle position sensor will not let your car accelerate normally. Though this doesn’t happen all the time.
Why does my Toyota engine stall while idling?
If I try to drive the car while it is still idling it stalls a lot. However the car still stalls a bit when it is finally warmed up but not as frequent nor as hard. I started looking on the web what it could be and still no luck.
Why do idle RPMs fluctuate in Toyota Prius?
If the butterfly is closed too much, the revs will drop too far forcing the engine ECU to open the idle control valve (IAC). It will then try to back off the air through the IAC, but since not enough air is getting passed the butterfly for idle, the revs will drop to far and so the surging cycle repeats.
What causes engine hesitation and stumble problems on the 90 +?
Then it developed an intermittent hesitation problem- you would be cruising at 60mph, on a 400 mile trip, ease off the gas pedal, and suddenly for 1/4 second, it was as though someone had switched off the engine and then turned it back on again. The car would then run faultlessly for the rest of the trip.
Why does my car hesitate when I hit the gas?
Whenever you took off from rest, the harder you jumped on the gas pedal the deeper and longer the hesitation. At higher revs the engine seemed to be a slightly down on power. Thinking the problem was related to vacuum, fuel delivery and improper fuel air ratio, I spent a lot of time looking at things in this area, but how completely wrong I was.
Why does my Mitsubishi Starion have engine hesitation?
As another example, I still have a 1987 Mitsubishi Starion, which ran perfectly for 35,000 miles. Then it developed an intermittent hesitation problem- you would be cruising at 60mph, on a 400 mile trip, ease off the gas pedal, and suddenly for 1/4 second, it was as though someone had switched off the engine and then turned it back on again.
What is the stopping distance at 60 mph?
Virtually all current production vehicles’ published road braking performance tests indicate stopping distances from 60 mph that are typically 120 to 140 feet, slightly less than half of the projected safety distances.
What to do if your car engine hesitates when you accelerate?
A good trick is if you drove your car right before doing this and the engine is still warm, just put the MAF sensor on top of the plastic cover of the engine for at least 15 minutes and the heat will dry it completely. IMPORTANT!
How long does it take for a car to stop?
(fps=1.467 * MPH). If the vehicle deceleration rate is 20 fpsps (rather than the previously calculated 15 fps), then stopping time = 88/20 = 4.4 seconds. Since there is a 1 second delay (driver reaction time) in hitting your brakes (both recognition and reaction time is often 2 seconds), the total time to stop is 5.4 seconds to 6.4 seconds.
