99 ford Contour 2.0 Zetec VCT engine.
I'm working on my granddaughter's 1999 ford Contour 2.0 Zetec VCT engine.
I just had a valve job done and had the head milled due to a blown head gasket.
I have had this thing apart and re-checked the timing on the cams many many times using the Ford flat bar and timing pin tools.
Everything seems to be correct but evidently it's not because the engine surges badly.
I scanned the OBD codes and got two codes, P0135 - Oxygen Sensor Heater circuit fault - Bank No. 1 and P1383 - Variable cam timing over-retarded.
Can't figure out what I'm missing and doing wrong as I think I followed the instructions correctly.
Here's how I've been doing it.
Set the balancer on the TDC mark
Inserted the timing pin.
With both cam sprocket bolts left just a little bit loose, I set the cams with the flat bard tool inserted and the #1 lobes on the intake cam facing the windshield and the #1 lobes of the exhaust cam facing the front of the car.
I tightened the sprocket bolt on the exhaust cam, then holding the intake cam sprocket so as to take the slack out of the timing belt between the two cam sprockets, tightened the intake cam sprocket.
Adjusted the timing belt tensioner.
Removed the timing pin and the flat bar tool.
Rotated the engine over 720° (two complete revolutions and back to the timing mark on the balancer.
Rechecked the cams with the flat bar tool and re adjusted the exhaust cam somewhat.
Like I said I'm obviously doing something wrong
One thing I didn't understand was putting the line between the little U cut on the metal piece behind the timing belt tensioner.
I mean I can bring it to that position but since it's spring loaded, I don't see any way to get it to stay there (it just springs back to where it was) ? ? ?
Anyone have any ideas?
