On a domestic car using a scan tool, the trouble code p0440 is an Evaporative Emission Control System Malfunction. It can mean the gas cap is not installed or working right, the purge solenoid has failed, or the canister is plugged and not working right.

My 97 Thunderbird is rough idling. I cleaned the bank 1 02 sensor and it still has a rough idle. I can floor it and the idle goes away.

You don't clean O2 sensors , if bad you replace them . An only if there is a DTC - diagnostic trouble code or you check out O2 sensor performance with testing , using scan tool , lab scope or multimeter . A rough idle is usaully caused by a vacuum leak , a engine misfire , IAC - idle air control air passages clogged . There are videos on youtube on how to test to find rough running problems .

Get a computer scan for trouble codes to see if that points you towards the problem. Possibly an engine sensor is not working right till it is warmed up. You might also check the idle air control for proper operation when cold.

2002 toyota highlander 4 cylinder check engine light blinking

A blinking light, like a "service engine soon immediately" light?
The only way to know why the engine computer turned the light on is to plug in a scan tool at the diagnostic port, and then the fault code or codes will be displayed. The code will refer you or a tchnician to a specific system, part, or circuit that the computer has detected a fault in. It probably is the cause of your running rough condition, also.
Some parts stores (Autozone, and other national stores) offer free scan service to retrieve trouble codes. Be careful of buying new parts just because the trouble code refers to them. Most trouble codes need a little testing and further diagnosis to pin-point the problem.
You can post the codes here for help, or take them to youir mechanic.

Timing belt replaced - ok for week, but now 'check engine light' on - rough idle - smooth at high engine rev

your scan tool should have come with an index of trouble codes, if not a service manual will have one. however i would inspect the IAC (idle air control) valve

1999 durango will suddenly stop running while driving. sometimes it will restart run alittle rough and then continues . Other times it will start .but run very rough and stops again, Sometimes I keep foot...

One and only solution you will need to do a OBD2 Scan to retrieve the vehicle computer errors your guess is good as mine what it could be this scan will pin point the exact problem.If you haven't the scan diagnostics tool most garages charge $25-$75.00 for this service

Check engine light came on and said map sensor. car has a rough idle, no power at take off. New map sensor was installed and car issues were not resolved. H E L P ! ! !

Did you clear the trouble codes with the scanner? OBDII trouble codes must be cleared with a scanning tool. If the codes are not cleared the computer could be in the"limp home mode". Once the codes are cleared, drive the car for at least one day. If there is no improvement, scan the engine again for codes.

Mis fires

The engine in your car is designed to run smoothly with maximum power output and produce as minimal emissions as possible. When your car's engine is not performing properly it can cause, low gas mileage, low power output, increased emissions and possible internal engine damage if left untreated. This troubleshooting guide is designed to isolate the malfunctioning cylinder and troubleshoot to repair the problem. Before we start we need to know one of two things; is the engine running poorly at idle only and seems to be ok under power? Or does the engine run fine and it's just the engine idle condition that is the problem. If your engine is idling rough please visit, engine misfires at idle If your engine cranks over but won't start visit engine wont start. If your engine won't crank over visit engine wont crank over. If your engine is running rough all of the time or intermittently you are in the right place. Below we have created a guide to aid diagnoses and repair procedure for most common rough engine running problems.

  • Step 1: Anytime you have a problem with electronically controlled components such as an engine, transmission, ABS brake, or SRS (supplemental restraint system, air bag) inspect all fuses in the under hood power distribution center and under dash fuse panels using a test light. If all fuses test ok continue to the next step.
  • Step 2: To check for problems with electronically controlled components such as an engine, transmission, ABS brake, or SRS (supplemental restraint system) and the fuses test ok a trouble code scan is needed to identify any system trouble. Use a simple scanner tool to retrieve trouble codes and check if they relate to the specific problem, like an ignition coil failure code. If a trouble code is present but does not pertain to the immediate problem like an EVAP code ignore it until a later time, after the engine is running properly. The reason we repair non-related codes after the engine is running properly is because sometime false codes can be triggered by a rough running engine. Once the engine is running properly the code present might cycle and turn itself off. You might say "if the engine isn't running right shouldn't it have a check engine light and a trouble code?" Sometimes conditions occur that will not be detected by the computer, example: if the intake or exhaust valve operation fails the computer cannot detect the failure because the problem is not sensor related, so the engine doesn't run smooth and the computer thinks everything is ok with no codes. If the trouble code retrieved relates to a cylinder misfire like an injector driver or ignition coil failure first repair these problems then re-test system. If no trouble codes are present proceed to the next step.
