hesitating/Misfire is back!!!*UPDATED*
Well after changing:
The coil pack
Water Thermosensor
AFM
Leads
Plugs
02 sensor
The problem came back this morning to my surprise. Last time the plugs and leads solved the problem.
I have had trouble free driving for like 3 weeks. This morning it did it again.
I am gutted.
Any ideaa where to look now?

An AFM will read the correct resistance per the workbook on test; but over the life of the AFM(years) the tension on the brushes inside the AFM gets weaker causing a disrupted signal. Zero volts is full load, so it throws extra fuel. Clean the contacts and move the brushes further against the sensing strip to cure this.(Under the black cover)

UPDATE:
On the way home from work she was good as gold and there was no missing whatsoever.
I have been doing some searching on the internet and found that magnecor leads have a not so good reputtion. I ran my old ones for 2 years without probs. the new ones have been on for less than 3 weeks and the missing happend this morning.
I have maybe an explanation to this.
I had a compression test done a week ago. It was also wet tested which means a small amount of oil was put into the 4 wells.
could this have broekn own the insulation on my new magnecors so quick?
or do you think the oil has not burned off yet causing the missfire?
THE CAR HAS NOT MISSED SINCE I CHANGED THE LEADS 3 WEEKS AGO.

update:
As I can imagine y'all are probably bored of me rambling on about my hesitation problem.
Anyway a friend wh works in a car audio shop said its an old car and have i checked my grounds.
I said the last time I checked the ground ner the oil dipstack was when I used it for the 4 wire 02 sensor wiring.
As a result he added a thick fuckoff cable from the engine (engine lifting hook) to the chassis (just in front of the power steering reservior.
I dont know if its me being silliy but it made a difference.
And this morning it did not hesitate nor did it hesitate back from work...was allot smoother.
Not I gonna change the ground strap near the dipstick and any otheres I can find.
Anyone know where all the grounds on a 1992 mx5 are?
