stylieee Posted February 10, 2006 Share Posted February 10, 2006 ok heres the situation... last week my radiator went big time (large hole), lost all the coolant and consequently broke down due to overheating (engine warning light, trc light, and plenty of smoke). the cars been sat for a week whilst i waited for my new koyo rad to arrive from the US, but today i got it fitted. the battery had died so i jumped it off my landrover batt. it started ok but refused to idle over 500, and when i blip it to try and correct the idle it drops to about 300 and nearly stalls before rising again. im assuming this is something to do with it overheating, as it was fine before (although just before the rad went i did notice a fair amount of smoke from the exhaust just as i was hitting full boost) any ideas ppl? i hate to have the soop just sitting there Link to comment Share on other sites More sharing options...
JohnA Posted February 10, 2006 Share Posted February 10, 2006 ouch, I hope it's nothing serious. At the very least do a compression test and keep your fingers crossed. Link to comment Share on other sites More sharing options...
andrew7 Posted February 11, 2006 Share Posted February 11, 2006 Hi Stylieee, Low battery will give you poor engine response, especially if it has fallen below half-capacity for any given time (they go kaput), which may compound any other problems you may have developed, like head-gasket, etc. Give your battery a proper charge off the car. See if it holds properly. Good luck.. Andrew Link to comment Share on other sites More sharing options...
JohnA Posted February 11, 2006 Share Posted February 11, 2006 once the engine is running, the battery *consumes* electricity, it doesn't give much. The alternator circuit takes over then. The real fear in this case is that something got overheated and warped. A consistent compression test will give some peace of mind. Link to comment Share on other sites More sharing options...
Markie Posted February 11, 2006 Share Posted February 11, 2006 Reset of ECU fuses? Could it be that the temp sensor for the ECU is a bit nacked? Link to comment Share on other sites More sharing options...
Paul Whiffin Posted February 11, 2006 Share Posted February 11, 2006 If the batteries gone flat completely chances are the ECU has been reset so it just needs some time to find itself, drive around for a bit and it should settle. If not may be some damage has occured when it overheated. Link to comment Share on other sites More sharing options...
JohnA Posted February 11, 2006 Share Posted February 11, 2006 That's interesting because that's what I thought when my battery had gone dead flat (11 volts or even less I think). Couldn't turn the engine at ALL. But the ECU didn't reset. Funny eh? Link to comment Share on other sites More sharing options...
