Dirty throttle body, Dirty idle air control motor.

Posted on Dec 24, 2016

Testimonial: "randy , thank you for the advice ...i cleaned the throttle body , and checked the idle control valve ..all clear done what you said ..but yellow on dashboard still on , and engine stil as sluggish as ever , no power at all , could it be the plug coils , thats not doing the firing properly.."

  • Randy Ohler Jan 05, 2017

    Could be spark plugs or coils. First 2 things I would do is a compression test on the cylinders and remove the top timing cover to check timing. If the belt is sloppy or a bit out of time, this could cause the problem. Low compression will too.

I have a 2006 Toyota 140i manual transmission. Whilst waiting at the stoplight with the engine at idle ,the revs suddenly race up to 4000rpm & come down on its own. What could be the problem .


Following are the reasons for unstable engine rpm:
- Vacuum leak at intake manifold or Cracked intake manifold.
- Idle speed control valve is not re-learned.
- Weak cylinder compression or intake valve clearance is too low.
- Mass Air Flow sensor dirty or faulty.
- Fuel pump pressure is too low or high.
- Accelerator pedal sensor faulty.

Why does my car jerk when i change the transmission from park to drive


the idle RPM is too high
or its just too cold,
how cold is it outdoors?
idle speeds cold can be about 1500 RPM/ cold.
and will ****.
it jerks because you are taking 0 torque from engine
and the sending that to a stalled rear axle.
this cause a ****, that is why the park lock out requires Brakes on
so yo dont run over things.

the po300 code is for a cylinder misfire, usually followed by a last number of 1 2 3 ect, showing which cylinder is misfiring, normally this can be fixed by installing a new set of plugs, the po171 code could be this
  • The MAF (Mass Air Flow) Sensor is dirty or faulty. Note: The use of "oiled" air filters may cause the MAF to become dirty if the filter is over-oiled. There is also an issue with some vehicles where the MAF sensors leak the silicone potting material used to protect the circuitry.
  • There could be a vacuum leak downstream of the MAF sensor. you cleaned that but it could be fouling out you could also have this happening
    • Inspect all vacuum and PCV hoses, replace if necessary
    • Check for a dirty fuel filter and proper fuel pressure

What is engine code P0171 for 2005 Toyota corolla?


What does that mean? Basically this means that an oxygen sensor in bank 1 detected a lean condition (too much oxygen in the exhaust). On V6/V8/V10 engines, Bank 1 is the side of the engine that has cylinder #1.
Note: This DTC is very similar to P0174, and in fact your vehicle may show both codes at the same time.
Symptoms You will more than likely not notice any drivability problems, although there may be symptoms such as a lack of power, detonation (spark knock), and/or a hesitation/surge on acceleration.
Causes A code P0171 may mean that one or more of the following has happened:
  • The MAF (Mass Air Flow) Sensor is dirty or faulty. Note: The use of "oiled" air filters may cause the MAF to become dirty if the filter is over-oiled. There is also an issue with some vehicles where the MAF sensors leak the silicone potting material used to protect the circuitry.
  • There could be a vacuum leak downstream of the MAF sensor.

2009 toyota corolla hesitates when accelerating. when acceleration in normal speeds, there is a delay of about 4-5 seconds in hesitating during acceleration. no engine lights are on at all. has about...


If you own a 2004, 2005, 2006 or 2007 Toyota Corolla and your car hesitates when you accelerate or it hesitates when driving, you should try the solution described here. Below is a list of the behavior your car may show that tells that you should try this procedure before going to a mechanic or repair shop.
  • The accelerator is slightly pressed while the car is running and it slightly jitters or hesitates
  • After completely stopping the car (a red light for example), it hesitates when you accelerate to continue driving
  • Engine power is below the usual level
  • Sometimes check engine light turns on
You should know that while those problems can be caused by several issues, including low quality or altered fuel or even a loosely tighten fuel cap, the most common cause is a dirty MAF flow meter sensor.
The MAF sensor (Mass Air Flow Meter Sensor) is in charge of detecting how much air (in mass, not volume) is coming in to the engine, so the ecm computer can calculate the amount of fuel to be injected.
Some times this sensor gets contaminated by lots of microscopic debris that scape the air filter and accumulate on its sensing parts over time. The resulting effect is that the MAF flow meter sensor gets less "sensible" and detects less air than it is currently entering the engine. The reaction of the ecm computer will be to inject less fuel to keep the air fuel balance, taking as reference the false reading of the MAF flow meter sensor. This will produce a too-lean mixture, which is responsible of the hesitation, the loss in power and the check engine light.
If your car engine, besides the hesitation, is also producing knocking or engine pinging at high loads, like when going up through a hill, it is attributed to this too-lean condition.
Before going to an auto parts store or to a mechanic to fix the problem, you should try fixing it your self. If the problem is a dirty MAF flow meter sensor, the solution is to clean it, plain and simple. That may save you some money that a mechanic will charge for cleaning it (you could do the same) or for replacing the part when most of the times it is not damaged, just dirty or contaminated

Have a eng code it show po 171 what do i do next


Enter the code in a Google search box and it will bring up a list of articles on the trouble code, such as the following:
A code P0171 may mean that one or more of the following has happened:
  • The MAF (Mass Air Flow) Sensor is dirty or faulty. Note: The use of "oiled" air filters may cause the MAF to become dirty if the filter is over-oiled. There is also an issue with some vehicles where the MAF sensors leak the silicone potting material used to protect the circuitry.
  • There could be a vacuum leak downstream of the MAF sensor.
Possible Solutions Possible solutions include:
  • In the vast majority of cases, simply cleaning the MAF sensor does the trick. Consult your service manual for it's location if you need help. I find it's best to take it off and spray it with electronics cleaner or brake cleaner . Make sure you are careful not to damage the MAF sensor, and make sure it's dry before reinstalling
  • Inspect all vacuum and PCV hoses, replace if necessary
  • Check for a dirty fuel filter and proper fuel pressure

Car jerks when running..ok at idle..distributor already replaced..tuned up..new fuel pump, filter..what could be wrong?


The Throttle position sensor may be worn or the maf sensor is dirty. The maf is in the intake ducting and can be cleaned w/ CRC electrical cleaner. Do not rub or brush the sensor, just wash thoroughly. The spray will dry quickly so no compressed air.

Power loss in 2004 Corolla Verso D-4D T2 at speed


You might want to check the MAF sensor(Mass Air Flow) and clean it with MAF/MAP cleaner. I am also kind of puzzled with this problem as I have a 2004 Corolla also, I only had power loss when my MAF went bad.
