New phenomena - idle goes up - no vacuum leak...

Postby AvivB » Sat Nov 21, 2009 10:10 pm

I have a new phenomena...
From time to time, when stopping in a traffic light or parking, the idle speed goes up to about 1400 RPM and the vacuum goes to 21...
Normally its 1000 RPM and vacuum is 19...

I don't think its vacuum leak since it'll reduce the vacuum but I searched for that anyway and didn't find anything.

RC engine, all stock, 10K after rebuild, <1K on the spark plugs + wires + dist. rotor & cap and clean TB.

Any ideas?

Is this with or without the a/c on? If so, it could be the a/c idle up vsv.

AC off.

TPS - When I disassemble the TB for cleaning I also recalibrate the TPS according to the book... and the IDL signal is connected at the right location.
Anyhow, I have a spare one from the previous engine... I'll try it...

Thanks,
