Hey i got an EL falcon, i did the timing on it, put the car in base mode. Started the car up, the idle seems to hover higher, then drop to around idle speed after around 15 seconds. Is this where i check the timing?

Over at Fordmods, someone told me you have to wait till the idle drops twice after the first high idle to check the timing?

So basically, start the car, higher idle, drop in idle after 15 seconds, then after around 1.5 - 2 minutes it drops once more, till it almost stalls, this is when to check the idle.

I did this procedure, right or wrong?

thanks

Its wrong
When you bridge the top & bottom l/h/s pins start the car, idle should sit on around 1700 revs therebouts. Do the timing then .. Yes you only have 20 or so seconds to do the timing before it reverts back to its normal mode.
Get your timing light out & check the timing its on ..
Should be 10 degrees????
If its alot higher its not in base timing mode.

ah so right after starting the engine, i got the wrong info!

Yeah i remember starting the car in base mode, and the idle is around 1700RPM.

thanks.

The timing should be checked after the rpm has come down, while the rpm is high the pcm is looking for the p/steer p/switch & brake light signals,IAC operation etc, then you can check timing. This is the self test mode, it is held for 2min's which explains why the idle drops for a second time.
