Hi,
77 MGB professionally restored, normally it runs nicely through the
gears with plenty of power. Lately, at about 65 MPH, any further
pressure on the accelerator is periodically met with hesitation and in
some cases a stall. Seems to be an intermittant problem but it occurs
at least once or twice per day of driving 50 miles. After a stall, I
have been able to restart with a downshift but in the majority of cases,
I end up on the side of the road for about five minutes (attempts to
restart immediately are met with ignition then stuttering then the
engines dies - the accelerator has no effect). After five minutes I can
restart and be on my way.
With the engine off and the igntion key on, the fuel pump keeps
chattering away for as long as I keep the key on; although, no fuel
leaks are apparent. Thought the pump was supposed to slow down or stop
pumping when it reached pressure.
At first, I thought there was a load of bad fuel; however, I should
have been past that by now and the problem persists and it is getting
worse.
So far these stalls only have occurred in fourth gear at speed. The
engine has no difficulty reving to over 3K in any other gear with no
signs of a problem.
