[urq] something's a-miss

[spot.ontheroad]

I recognise the "blehhhh" (and that is how you spell it). I recently had to
have my fuel tank repaired, I dried it out and refitted it. All was fine.
Then it started to miss occasionally, usually at higher revs. Then it
started to happen more frequently and at gradually lower revs. The miss was
instant and short duration and felt very "electrical".Then the duration of
the miss got longer hence the "blehhhh".  We tested everything electrical.
Then with further road testing we noticed that the air/fuel meter showed a
sudden weakening of mixture just before the miss. If it had been electrical
the mixture would have richened. So now we knew it was fuel. I disconnected
the tank outlet and the fuel struggeled to drain out. A blast up the pipe
with compressed air led to a blob of gel-like emulsion dropping out followed
by a full flow of fuel. I flushed the tank through repeatedly with a few
gallons (filtering it each time) and put it all back together. It has been
fine since.
One clue I should have spotted was that the fuel pump was whining as it
strained to suck fuel. It no longer does this.
I hope this helps.

Guys-

 My car has been running exceptionally well for about 9 months now. Nooo
problems at all. Until this past weekend.
 I romped the gas up to about 5500 RPM in 1st, 2nd, and 3rd. When it got to
about 3500 in 3rd, I felt it go flat...not like the 4k rpm cut -out.  It
just went "blehhhhh". Now I have an intermittent miss in the motor. I
replaced the wires, coil wire, rotor and cap. It did nothing. I checked the
injectors to see if they are seated tightly and they are. No vacuum leams
that I can find as of yet, the car dies upon removal of the oil cap. I used
a timing light on all 5 new wires and they seem to have a rhythm to their
pattern.

Any ideas??
Gary
