Hello! me again.
I'm still fighting this cam surge.
I've tried just about everything I've read about.
I've just scoured the gearhead site & the web on suggestions.
Read up threads by Dave_W, Scott PFautsch, Steveo, Bobdec and Greg Banish.

I've jacked timing up and down without much effect.
I've just driven back from the anual MOT test with the timing retarded by 15 degrees, idling at 20.

Ideally...
The car idles at 39 degrees very nicely, map around 38-41.
It will pull away by just easing the clutch out & no throttle, dead smooth and no bogs.
As the car gets upto rolling speed 6-9mph the car starts having a fit, mild to wild.
Any throttle and load say 5% and more and the car seems quite happy.
If i hold the throttle until the revs settle (lower map around 30) it will still surge.
Any time I slow down, drop to 2nd (10-1400rpm) and turn a corner it's there until you hit the gas a small amount.

Idling with timing at 34 the car is sluggish and soggy when pulling away. Map around low-mid 40's.

I've tried timing upto 45+ in these higher rpm lower map areas.
I've lowered it down to 35 at 2800 rpm.
I've just pulled 15 degrees off the table with EEHack and IT'S STILL THERE.
It was idling at 20 degrees.

Fueling has noticably been effected.
Where BLM's were 125 to 129 they are spread 120/116 upto 139/139 and splits upto 5
BLM 16 is reading 133 131 & O2averages are sat at 494/484mV


Is this a symptom of the cam?
It's not huge 223/231 .610/.594 112 LSA.

Currently running CLSD.

Any ideas
