Zetec Timing problem

[1turbofocus]

I am trying to help but you dont seem to want to listen , you CANNOT read a plug to tell ANYTHING about whats going on as for fuel or timing on plugs that have been heat cycled and run on , its only std practice for those that dont know it is not the proper way to read a plug and unless something is dumping LARGE amounts of fuel into the engine the plugs will always look white and then most will say its running lean which if the plug is tested correctly will look like a brand new plug you you have to look deep into the plug to check the fuel
The timing on the plug cannot be checked unless you do go WOT , and sence you say this isnt for WOT then i am sure you have checked the short turm fuel trims to see that the fueling in hitting stoich and no need to be checking the plugs for fueling issues so why check the plugs ?

As for my "weird macho" you need to be clear what your asking if you want help 90% of the people here didnt know what you were talking about and why you didnt get any help

As for checking the MAF you should be watching the Voltage as the car idles and rev and hold the RPM and see if the voltage is moving this will be the best way to test the MAF

But again your best bet is to find a local member that has the xcal this will check all your sensors and give you readings to help find the problem

I not trying to bust your balls or give you a hard time , your just going about things wrong and taking my advise/opinions as being weird macho and that isnt the case at all

What exactly does the xcal read?

Sensors related to timing changes
IAT
ECT
TPS
Crank trigger
MAF
knock sensor
a/f ratio

Things that change a/f ratio
IAT
ECT
bank1 sensor 1 o2 sensor
bank1 sensor 2 o2 sensor
TPS
MAF
WOT


Cam sensor does not change timing , you dont even need the cam sensor to run the engine on the Zetec

The xcal will check each of these sensors and hundreds more giving you actual readings of what the ECU is seing
