Car Forum / Ford / Ford Focus / May 2007Intermittent Idle Problem
Hi, My year 2000 UK Focus has developed an intermittent fault. Normally it's when the engine is warm, and I've been travelling above 60mph. When I take my foot off the accelerator, the car will keep going at roughly the same speed. If I dip the clutch, the engine can race to as high as 4000rpm. Could this be the ISCV I keep seeing references to? thanks in advance Phil >Hi, > [quoted text clipped - 8 lines] > >Could this be the ISCV I keep seeing references to? No, its more likely to be a problem with the throttle position sensor.

If the car is on the warm up say no more than a couple of minutes from cold start, then this is normal and is a peculiarity of the ECU software. If it still does it when hot then you have a problem, possibly with the TPS. 1.8 and 2.0 cars are most affected.

I took out the TPS and just sprayed it with cleaner, put it back in, and it seems to have solved the problem for now. I don't know if I'm imagining it, but it seems a bit nippier around town now, a bit more responsive. Is this possible? Ta Phil |
