Mistry Posted November 20, 2008 Share Posted November 20, 2008 Hi everyone, I recently had an issue with engine revs falling to zero when I pressed the clutch down fully. This only ever happened when the temperature outside was very COLD. Once engine is warmed up, all is fine. I thought the problem was solved a while ago but I was wrong. :( So far the car has had the following done: - New battery - New oil filter and oil - Cleaned air filter - Cleaned throttle body - New IAC valve - New spark plugs But problem still occurs! To best describe it, the car fails to 'catch' the idle speed when the clutch is dipped during cold running. If the engine is revving at 3000rpm or above and I press the clutch and keep it there, the revs more or less always drop to zero causing the battery light to come on. As the engine continues to run the problem slowly dies down. I am beginning to suspect the TPS, only becuase I disconnected it while the engine was idling and no change was noticed. Does the operation of the TPS depend on outside temp? Any advice apprecieted! Quote Link to comment Share on other sites More sharing options...
mintalkin Posted November 20, 2008 Share Posted November 20, 2008 it could be the tps or a temp sender unit playing up without further investigation its hard to say. Quote Link to comment Share on other sites More sharing options...
Mistry Posted November 20, 2008 Author Share Posted November 20, 2008 I recently did have a diagnostic done when my car was misfiring. Coil pack and HT leads showed up as problems, which were replaced and cured the misfiring but nothing else showed up regarding this problem I've had for a while now.

Mistry Posted November 24, 2008 Author Share Posted November 24, 2008 Anyone? I found others with EXACTLY the same problem as described in the first post on other forums but no one has managed to get it solved. Quote Link to comment Share on other sites More sharing options...
