Speedo will cut out when driving

Are sure it is cable,low idle has limit is set up to stay the same.

The cluster is really a computer module, so what needs is first make sure the signal for this gages are reaching the cluster if they are then the cluster needs repair, if not you may have a defective fuel level sensor and a problem with the vehicle speed sensor. Flip a coin, the sensor issues will be the most costly as the fuel tank must come out for replacement of the level sensor, that runs many hours of labor.

Hi there,

This does sound like an electrical issue.

However, you should NEVER replace any component, until you have extracted your vehicle's OBD codes.

Do this by the following method:

• Rev the car to 2500 rpm (while in Neutral or Park), then slowly reduce revs down to idle.• If equipped with automatic transmission, cycle through each position (Drive, Park, etc).• If equipped with air conditioning, also cycle that ON and OFF.
1 Turn engine OFF.2 Retrieve the trouble codes: turn the ignition ON-OFF, ON-OFF, and finally ON again (within 5 seconds).3 The stored 4-digit fault codes will be displayed in the odometer (speedo) display area.
Reply back with these codes and we can assist you further.
Cheers,

Hi, I had the same problem. For my malibu (2000) it was a faulty ignition switch. I replaced it and the instrument panel works fine.

My 04 Ford Focus the battery light keeps coming on & going off, have fitted a new alternator belt but it didn't solve the problem. The battery connections are good. Also the rev counter, speedo & mileage clock keep going haywire when the battery light is on. Do you think it is the alternator? Or is it some other common problem?

The first thing you do is have the engine control module scanned for fault codes. I also suggest you buy a can of spray throttle valve cleaner and clean the throttle valve and the idle speed control valve.

its sounds like a transmission problem, but my wife's car had a bad intake gasket that caused the same problem!

speed sensor on the back of gearbox

it's your idle air valve located on the backside of your intake round with two large lines going to it make sure you check junkyards first for one because you'll faint when you hear the price at the parts counter.

try replacing your EGR Valve, or your Oxygen Sensor
