Hello!
I have a '74 manta A with 2,0 L-jetronic injected engine; standard ignition over points..
The problem looks like this (and my friend with ascona has the SAME problem...):
if you drive the car without acceleration at high revs (for example at 4000rpm) it jerks - feels like it's loosing sparks or something. Besides that, in friend's ascona the rev meter starts jumping around. Then, if you connect direct +12V from the battery (bypassing the original resistor wire) it drives like new - but of course we'd fry the coil if we drove like that all the time!
We tried everything - new cap, condenser, rotor, points and their gap, ign. cables, 3 different coils, we measured the voltage at the coil and it is OK (even during the "jerking session"), changed distributors (altough we still suspect them...) - but nothing works... damn
any ideas? I can't go to sleep because of that...
