Could be a bad instrument panel(IP). Rough idle in gear could be a vacuum leak. Maybe a tune up.

SOURCE: Rough idle at start up

My 1997 lesabre has developed the same problem. I replaced plugs,wires,pcv valve and O2 sensor to no avail. Also tried several tanks of high octane. Yesterday I left the store and it wouldn't start at all. Had the car towed to a good local shop. Today they said it starts fine and has been all day! They checked everything they could think of and can find nothing wrong. The head mechanic suspects the crank sensor but said it should give a check engine lite if it was having a problem. Of course the third time I started it after picking it up the damn thing barely ran for a minute or so before finally smoothing out. No check eng lite. This is becoming very frustrating!

SOURCE: Engine backfires when accelerating

Idle is rough because not a right Air/ Gas mixture.
The ideal air /gas ratio is 14.6:1. If less than that it has rich mixture. If it more then that it has a lean mixture.
Back fire happens when accelerated because of of rich mixture pumped out at exhaust cycle is burning.
At speed above 40 miles/hour, temperature and fast compression cycle make the problem is less obvious.
Cheap first shot is to replace the air filter to correct this ratio. If it doesn't help, need Fuel distributor service. ( However people like to make easy money from you first, they will convince you for a turn up) Good Luck. I'll check back to see how the progress going.

SOURCE: rough idle on 2008 chrysler towne and country

The following are the general instructions on the start of diagnosing any electronically controlled engine or transmission problem.

The engine and the automatic transmission (transmission control is only for automatics, engine is still computer controlled no matter the transmission type) in this vehicle are computer controlled and in most cases when a fault occurs a fault code is stored in the memory of the computer control module. There are exception to this, such as the Mass Airflow Meter and fuel pressure problems. What must be done is to have all the basic testing done such as a scan of the system for fault codes as well as a check with a live data scanner tool for engine functions that are not within range of normal, a trained technician is required to know what is correct and what isn't, then based on careful diagnostics done from a factory repair manual the correct part is replaced or the wiring repaired or the computer replaced (known as the PCM or ECM,ECU), which is very rarely the problem. Other basic checks must be done as well such as mechanical problems with the engine as well as engine state of tune and mileage on the engine. The transmission can have mechanical issues as well such as no gear engagement at all or a failed pump or other pressure related problems. Also engine mechanical problems can and do cause many drive-ability related problem such as rough idle and other symptoms.

For anyone doing a search on the same symptoms, this is also very indicative of a lean condition on this vehicle. While not enough to pop a code, 10% long term fuel trim will cause these same sysmptoms...troubleshooting the lean condition is an entirely new topic.

Doesnanyone have a diagram showing where the wires on a speedometer connect to? I need to see if i pulled it on accident. And fuel gauge. Im learning so pictures are easier. Thx 2001 chevy tahoe


The speedometer gauge is controlled by information sent over the class 2 data bus from the PCM/ECM - engine computer . There is a VSS - vehicle speed sensor mounted on the transmission , this VSS is a input to the engine computer .
Speedometer
The IPC displays the vehicle speed based on the vehicle speed signal from the PCM. The IPC- instrument panel cluster receives the vehicle speed signal via a discreet wire. The IPC uses the vehicle speed signal circuit (4000 pulses/mile) from the PCM in order to calculate the vehicle speed. The speedometer defaults to 0 km/h (0 mph) if a malfunction in the vehicle speed signal circuit (4000 pulses/mile) exists.
Is the whole instrument cluster dead ?
Fuel Gauge
The IPC displays the fuel level as determined by the PCM. The IPC receives a class 2 message from the PCM indicating the fuel level percent. The fuel gauge defaults to empty if:
• The PCM detects a malfunction in the fuel level sensor circuit.
• The IPC detects a loss of class 2 communications with the PCM.
When the fuel level is less than a pre-determined value, the low fuel indicator illuminates.
Reviewing the fuel system description will further explain how the system functions. Refer to:
• Fuel System Description in Engine Controls - 4.3 L
• Fuel System Description in Engine Controls - 4.8 L, 5.3 L and 6.0 L
• Fuel System Description in Engine Controls - 6.6 L
• Fuel System Description in Engine Controls - 8.1 L
Hourmeter
The IPC can display the accumulated engine run time hours using the VF display when the cluster is in the LOCK or ACC position. The IPC stores the accumulated engine run time hours in a non-volatile format. The accumulated hours will not change if the battery was disconnected or removed. When the ignition is OFF and the trip reset switch is pushed in and held for more than 4 seconds, the IPC will display the accumulated hours for 30 seconds. The hourmeter will reset to 0.0 when 10,000 hours are accumulated.
Odometer
The IPC contains a season odometer and a trip odometer. Momentarily press the trip/reset switch on the IPC in order to toggle between the season odometer and the trip odometer. Press the trip/reset switch for greater than 2 seconds, while the trip odometer is displayed, in order to reset the trip odometer. The IPC displays the vehicle mileage and trip mileage as determined by the IPC. The IPC calculates the mileage based on the vehicle speed signal circuit from the PCM. The odometer will display 'error' if an internal IPC memory failure is detected. The odometer can be configured to display either miles or kilometers.
PRNDL Display
The IPC displays the selected gear position as determined by the PCM. The IPC receives a class 2 message from the PCM indicating the gear position. The PRNDL display blanks if:
• The PCM detects a malfunction in the transmission range switch circuit.
• The IPC receives a class 2 message indicating the park position and the column park switch indicates a position other than park (open input).
• The IPC detects a loss of class 2 communications with the PCM.
GM had problems with stepper motors that control the needle position .
Your best bet buy a used instrument cluster from the auto slavage yard .

After getting gasoline, it increases wrong mileage with camry 2003


One tank of gas is not enough to compare mileage. Or are you saying the computer's readout of mpg estimate is showing less? Try a tank or two of premium and see if that helps. Keep track of gas mileage. Driving techniques have a lot to do with gas mileage, as does long trips vs. short trips, highway cruising vs. city driving. For best mileage, do regular maintenance and keep the car in top running condition-good spark plugs and clean filters and clean oil ! Attend to minor problems before they escalate.
If you want to check actual miles per gallon, start with a full tank. Write the odometer reading down, and go. Everytime you put gas in, write down the amount. When you are close to 1,000 miles from the time you started, go fill the tank and include that amount of gas to your previous list. Now add up all the gas used and divide it into the miles to get miles per gallon. (976 miles/31.8 gallons = 30.69 mpg ) . Only one tank will skew your numbers, might be off cause the tank was filled more to the top than the previous fill-up. About a thousand miles of driving will give you a very accurate figure of miles per gallon for your car.

1988 toyota crissada,runs hot,idles to high.going 5 miles per hour and speedomter say 130 mile per hour,has very little power.


While the engine runs hot there is a possibility that the RPM sensor goes off and shows the wrong reading. First of all check the cause for the overheatting before we can go further.
Some tips were given in your earlier request.

You will need to pull the speedometer out and have the odometer (u call mileage counter) repaired, the little drive gear that comes off the speedometer to operate the odometer has failed or broken.

Speedometer is 5 mph off.


Most speedometers are off by a few miles per hour even when new, this is normal
but yours could be caused by putting different size tires on the car check the owners manual for correct size tires
