85 AE82 Corolla Seca
Greetings from Aus
Have a question regarding the above mentioned machine that is equipped with
a 5 speed manual.
It was hesitating under load (2, 3 and 4th gears), ok in 1st and top.
Changed plugs, distributor cap, checked plug lead resistance (all under 20 K
ohms/metre) as well as obligatory fluid change with filters, carb cleaner
down carby and new fuel filter. Adjusted timing, and changed coil (outside
of resistance specs). So far, the car has improved dramatically, yet when
it gets upto operating temp begins to hesitate and miss in the 3000-4500
range. The tacho is jumping about 200-700 rpm jumps and I am at a loss to
discover why
What is going on?
Also, I changed the dizzy cap as the plug poles showed an odd corrosion on
them. This corrosion has returned in under 300 kays of driving.
The mech advance and vac advance are working on the dizzy (confirmed with
timing light).
Are the electronic ignition systems on these things responsible for this
erratic tacho behaviour as well as the poor acceleration and missing in the
3000-4500 rpm range?
How can I get the tach to behave?
Very interested in any ideas that are out there!
Cheers
