I have ssangyong 2006 diesel rodius 220,000 Kilo meter full service history some time wont start & orange engine light staying on lights were losing power and car was chucking/missing whats the...


have a load test done on the battery as it may be failing and not providing sufficient power to run the ECM. Check for alternator drive belt condition and tension. The combination of low current out put from the alternator and bad battery especially in cold weather will cause problems as describe.

My 1994 5-speed manual Pathfinder sputters and jerks when it's cold


Here are the common cause of surges, stalls at stops, slow idle speed, erratic idle, it is in most cases the idle speed control air-bypass valve and/or throttle valve and upper intake, these area's get full of gunk and combustion residue over the miles and cause idle issues (stalls, low idle) like yours, Get a can of intake cleaner from any local parts store, not carb spray, intake cleaner, it is made by a company called CRC, remove the air intake hose to the engine, hold the idle high so the engine won't stall, then spray the can of cleaner into the intake while keeping the engine running, use at least 1/2 the can, shut down the engine and disconnect the battery for 5 minutes, then restart and complete a number of mixed driving

Coaster idling high and high fuel consumption


Water temperature is low cost oil is certainly the easiest way is with a hard shell to block part of the warming effect of the radiator well as for how much you want to try to stop. Idle temperatures will rise up relatively low. What is the pull speed? Not run fast but continues to run uninterrupted some time. Usually two hours can be. Is to allow the engine to reach full swell purpose. Such a shift is to be based on the vehicle speed and the reference engine speed. Not based on the engine speed. Driving is probably the single 30 towards third gear, fourth gear towards forty, fifty five-speed ahead. Many people on the car ahead of change. As long as the engine sounds smooth, no trailer can be.

Idle problem integra


check the MAP sensor (manifold absolute pressure). The ECM (car computer) uses that to keep idle at minimum 750 RPM. It's normal for it to run high when cold. These small 4 banger motors typically run hot, and they won't run right IF they're NOT running hot, ergo the idle is usually high when it is cold so as to cause it to warm up quicker. If the RPM's drop below 750, suspect the MAP sensor, &/or ECM.

1991 dodge colt won't idle when engine is cold.


probably oil, it may be too thick when it's cold but once it warms up it liquefies and your engine runs smoothly. you could try changing oil, I'm guessing if you have a high performance oil the chances this is the problem may be greater since high performance things are usually geared towards working well when everything is hot
