Daewoo Leganza - Recent Questions, Troubleshooting & Support

hi there are you able to remove stereo if you can i will need the serial no on side of stereo get me that & i will get your code.

This P0507 code is one that's sometimes triggered on vehicles that have electronic throttle control. That is, they don't have a regular throttle cable from the accelerator pedal to the engine. They rely on sensors and electronics to control the throttle. In this case, the P0507 DTC (diagnostic trouble code) is triggered when the PCM (powertrain control module) detects an engine idle speed that is greater than the desired (pre-programmed) RPM. In the case of GM vehicles (and possibly others) if the idle speed is over 200 rpm higher than expected, this code will be set. A P0507 DTC trouble code may be caused by one or more of the following: A vacuum leak Leaking air intake after the throttle body EGR valve leaking vacuum A faulty positive crankcase ventilation (PCV) valve Damaged/failed/dirty throttle body Failed EVAP system Failed IAC (idle air controller) or faulty IAC circuit. This DTC is more of an informational code, so if there are any other codes set, diagnose them first. If there are no other codes, inspect the intake air system for air or vacuum leaks and damage. If there are no symptoms other than the DTC itself, just clear the code and see whether it returns. If you have an advanced scan tool that can interact with the car, command the idle higher and lower to see if the engine responds appropriately. Also check the PCV valve to see if it's blocked and needs to be replaced. Check the IAC (idle air controller) if equipped, verify it's operation. If available, try swapping in a new throttle body to see if that fixes the problem. On Nissan Altimas and possibly other vehicles the problem may be fixed by having the dealer perform an idle air relearn procedure, or other relearn procedure

Check the coil pack maybe braking down under a load.unplug each plug to see if there is any change may have week pack.if no change do a compression check on all cylinders.

Sounds like low fuel psi .try changing fuel filter

you need to replace the window regulator there not made to repair

Best Manuals just go to www.Reliable-Store.com I attached I'm sure you will get the correct AND complete manual AND instantly

5th gear synchronizer warn faulty damaged or dry. if you can check the level of the oil in the gearbox to see if its at it top. ( dun by adding more oil) if it overflows straight away then its full and not the problem. automatic, it can be a sensor fault either getting wrong signal from abs or the engine rev counter, or again low level of oil in auto box.

Call the auto part store or go to the local library and get a manual.

You have trans slippage. Check fluid level and condition. Your trans is probably fried.

Did the car overheat at one point? That's a symptom of an overheat and a cracked head.

You might have a bad hydraulic valve lifter (assuming this engine has them)... you could try an aftermarket product designed to unstick valve lifters.... any auto parts store carries them.

the problem is that you have allowed it to degenerate to the point where it can be a costly fix where at the time the engine light first came on , a trip to the local auto spares shop would result in a fault code reading for free have the fault codes read now check the oil levels and coolant levels at the radiator as it could be the result of and overheating peroblem

have it checked by an accredited service center

need to read codes with a transmission scanner

that's a major job, head removal and rebuild after a T-belt breakage, and hard to say if he has left something disconnected or mis-connected, or if it picked now for some other fault to develop. I've worked on those Daewoo c2000 2.0/2.2 16v GMH engines a bit, my friend bought a 1998 Leganza, I always figured them as a POS engine, frankly..he had more than one major problem with it, even though we avoided a T-belt failure.

Sounds like a vacuum leak ,,causes lean condition ,can cause internal engine problems ,
