The speedometer in this car is electronic, no cable, in your case the speedometer is defective I'm sure. You will need to remove the instrument cluster from the dash and have it repaired by a local shop that does this type of repairs. Call the dealer for a phone number and name of the business they use for instrument cluster repairs like this.

Your clutch has failed. Big job...transmission needs to be removed. The over-reving you felt was the friction material on the clutch disc not gripping the flywheel.

Both fault codes are refer at air intake system; check this information to solve it...

P0103 - Mass Air Flow (MAF) Circuit High Input
Basically this means that there is a problem with the Mass Air Flow High (MAF) sensor or circuit. A more technical description would be that the MAF circuit had higher than expected voltage (air flow). Other MAF sensor circuit DTC trouble codes are P0100, P0101, P0102, and P0104.

Symptoms: You will likely not notice any serious drivability problems, although there may be symptoms such as a general decrease in power or sluggishness.

Causes: A code P0103 may mean that one or more of the following has happened:
The MAF may be disconnected, or a wiring connection may be bad
The MAF sensor may be damaged
The vehicle computer may be faulty (very rare)

Possible Solutions: The simplest thing to do is to reset the code and see if it comes back. Then start with the cheapest, easiest repair procedures:
Verify that the Mass Air Flow Sensor wiring is connected properly and that there are no broken / frayed wires.
Inspect for any air leaks near the MAF sensor.
Take the MAF out and clean it using a spray cleaner such as brake cleaner or electrical contact cleaner. Be gentle with the sensor.
Check the voltage of the MAF sensor (refer to a repair manual for vehicle specific information)
Replace the MAF sensor.


P0113 - Intake Air Temperature Circuit High Input
The powertrain control module (PCM) monitors the temperature of the air entering the engine. The PCM supplies a 5 volt reference voltage to the Intake Air Temperature (IAT) sensor. The IAT is a thermistor that varies resistance based on temperature. As the temperature increases, resistance decreases. Low temperature results in a high signal voltage. When the PCM sees a signal voltage higher than 5 volts, it sets this P0113 check engine light code.

Potential Symptoms: There will likely be no symptoms other than illumination of the Malfunction Indicator Lamp (MIL - Check Engine Light / Service Engine Soon).

Causes: A code P0113 may mean that one or more of the following has happened:
Internally failed IAT sensor
Faulty connection at IAT sensor
Open in IAT ground circuit or signal circuit
Short to voltage in IAT signal circuit or reference circuit
IAT harness and/or wiring routed too close to high-voltage wiring (e.g. alternator, spark plug cables, etc.)
Faulty PCM (less likely but not impossible)

Possible Solutions: First, if you have access to a scan tool, is there an IAT reading? If the IAT reading is logical then the problem is likely intermittent. If the reading is less than -30 degrees, unplug the connector. Install a jumper wire between the harness connector signal and ground circuits. The IAT temperature reading on the scan tool should be maxed out at the high end. For example it should be 280 degrees Farenheit or higher. If it is, the wiring is okay, and it may have been the connection. If it isn't install the jumper wire between the IAT signal circuit and the chassis ground.

If now the IAT reading on the scan tool is maxed out then check for an open in the IAT ground circuit. If you get no reading at all on the scan tool, it's likely that the sensor signal is open or the 5 volt reference is missing. Check using a DVOM (digital volt ohm meter) for a 5 volt reference. If it's there, then unplug the connector at the PCM and check for continuity on the IAT signal circuit between the PCM connector and the IAT connector.

Other IAT sensor and circuit related DTCs: P0095, P0096, P0097, P0098, P0099, P0109, P0110, P0111, P0112, P0114


Check it, test it and keep us updated.

your electric fan for the AC is not working for whatever reason so when idles its all getting hot the engine and the AC system .This sort of work can be difficult to diagnose correctly and a code reader is about as good as a bible at mosque so seek the advice of a skilled mechanic who should be able to pin point the fault in seconds

Get the engine codes pulled. Once you have them it will help track down the issue. Not really much you can do otherwise unless you want to throw money at it.

I drive a Chevy Venture 2004. in the mornings, when I start up the engine, the brake pedal goes down when I push it. Sometimes, when I am driving slow and I push the brake, it goes down, more than normal....


first check brake fluid level
if fluid is low, this is a good indication that pads or shoes need replacing
check brake lings for wear
check that pcv valve from engine to brake booster is not clogged
to check this pull it out of valve cover and shake it
if it rattles it is good
if it dont rattle it is clogged,replace it
if pads and linings are good and no obvious signs of brake fluid leaking anywhere,(wheels cylanders etc>then the brake master cylander or brake booster is bad
more likely to be booster

The car slowes down after drivin few miles,


Look at your fuel filter, It could be clogged and is restricting the high flow of fuel required at speed. This happened to my old Holden Commodore here in Australia. Fuel filters are cheap and quite easy to replace, usually located under your car on the fuel line near the tank or in the engine bay . One more thing to note..... Check your fuel hoses connecting your fuel filter, if they are kinked the same thing will happen.. Always give your fuel easy flow paths, put a large loop in the rubber hose either side of the filter if the hose will kink or the space is tight......
