A blinking check engine light usually indicates a misfire. It could be a bad plug, a bad coil, a bad wire, or a condition known as carbon tracking.

Pull the codes first. This will narrow down what cylinders are being affected. I'm betting you have one of these codes P0300, p0301, p0302, p0303, or p0304. The last number of the last four i listed are the specic cylinder that a misfire is on.

Let me know what you have for codes.

Let me know if you have any questions. Thank you for using FixYa.com!

SOURCE: 2001 Toyota corolla hesitates on acceleration

Basically this means that an oxygen sensor in bank 1 detected a lean condition (too much oxygen in the exhaust).

SOURCE: Running rough and buzzing at throttle body injectors

Sounds like the engine has a vacuum leak at the throttle body area.

SOURCE: 2000 toyota corolla hesitates when you hit the gas.

i would check your fuel filter and air filter first if they are dirty then i would change them. and if it still does it then it might be one of the sensors on your throtttle body. like your tps sensor or the iac valve or it could be your mas sensor you can also clean these with some throttle body cleaner and mass air flow cleaner that you can pick up at any auto parts store

SOURCE: 99 toyota corolla hesitates while excellerating

Are you one of those people who TOP OFF the tank when filling up?

When the EVAP recovery system soak with few ounce of gasoline......the trap vapor will take few days escape.

EVAP system is design to handle fuel vapor. Few ounce of gasoline can damage the fuel vapor recovery relay and decrease the service live of the recovery lines.

=========

You can accelerate the process by locating the charcoal canister (near the nose of the car and same side as your gas filler door)

MOVE the car to outdoor.

Disconnect the EVAP line and let it air out by itself.

DO NOT introduce any heat source or fan to speed up the process.

Reconnect this EVAP hose and use a small amount of starting fluid at the intake manifold.


Please post more information by Clicking on the comment link.

I will follow up.

hi, i would like to advice you check the electronic idle speed control valve and also check engine coolant temp sensor. The ISC (idle speed control valve) is located somewhere below the throttle valve. the engine coolant temp sensor is located near distributor. it has a two wire connection. the sensor connector is usually green

Motor hesitates & bucks after slowing down & then re-accelerating


HMM, it has been awhile since ive worked on that toyota motor. Check for vacuum leaks on hoses and the intake manifold. Check egr system for a dirty pintle leaving the egr stuck open. It will cause bad acceleration and idle quality. A properly closed egr cannot be blown through to the opposite port. Check for a clean throttle plate, if it is not, clean it. If it is a fuel injected engine check for bad fuel injector o rings for wear, if they leak they cause fuel burning and idle problems.

Engen problem and missing


Sir, your question is not very clear, but I will still try to post a solution here. Engine missing could be due to any problem in fuel system, ignition system, engine or ECM as well.

LOW ENGINE IDLE SPEED (Poor idling):
-Throttle body (do the cleaning and idle speed learning)
-A /C signal circuit
-Fuel pump control circuit
-Fuel pump
-Intake system
-P C V valve (clogged or open) and hose

ROUGH IDLING:
-Cylinder Compression
-Ignition system (Igniters, spark plugs, wiring harness)
-Spark plug fouled, gap too wide or too short. (1.00-1.1 mm)
-Fuel injector circuit
-E C M power source circuit
-Fuel pump control circuit
-Fuel pump (required pressure 44 psi - 49 psi)
-Throttle body (cleaning)
-Intake system
-P C V valve and hose
-Air fuel ratio sensor
-Heated oxygen s ens or
-Mass air flow meter
-Idle hunting
-Throttle body
-Intake system
-P C V valve and hose
-Air fuel ratio sensor
-Mass air flow meter

HESITATION/ POOR ACCELERATION:
-Fuel pump control circuit
-Fuel pump
-Spark plug
-Ignition system
-Fuel injector circuit
-E C M power source circuit
-Mass air flow meter
-Throttle body (do cleaning)
-Intake system
-Valve timing
-Cylinder Compression

2003 SATURN VUE SERIVE ENGINE SOON LIGHT IS BLINKING ON AND OFF RAN THE OBDII READER AND CODE P0304 CYLINDER MISFIRE CAME UP I CHANGE SPARK PLUGS AND BOOTS BUT CAR STILL DRIVES ROUGH SHAKES AND WHEN PARKED...


The P0304 indicates the #4 cylinder is misfiring. The flashing light means the cylinder is not firing at all...It could be several things causeing it, coil, wires, plug, injector or vacuum leak. Do not drive your vehicle until you have this repaired, as it will lead to further more costly problems. Good luck, i hope this helps.

Rough idle and hesitation but runs ok driving around new plugs wires hell its a brand new motor


Did you check your injectors? It could possibly be a bad fuel filter or pump. Replace the filter, its along the driver side frame right as the bed starts. If thats not it check the fuel pump

Strong fuel smell


You more than probably have a gas leak somewhere in the fuel system. If you can smell gasoline, it is leaking somewhere. The lines run along the frame to the engine. The leak might be hard to see or hidden (on top of the fuel tank).

The leak is robbing fuel pressure from the engine, causing it to idle rough, so is probably on the pressure side of the system.

(Most fuel systems, except for "returnless" systems with Pulse width modulated fuel pumps (not very common), have a pressure line and a return line to the tank.
