    I'm in a 308 GTSi 82, restoration process, ussually the car starts and runs ok, but now after couple months at the shop (probably they didn't start the engine often) I drove the car for a while and I founded that is with very low power, you can't go faster than 50 mph.
    I already change the coils, wires, rotators, plugs.
    I took out the calalityc convertors (here we don't have emissions control for vintage cars)
    Any suggestions about this issue?
    Thanks in advance
    JC

    You should first confirm/deny if you have spark on both banks. Your model has an ignition architecture where the two banks are very independent from each other. If you have lost one bank of ignition, the most likely culprit is the TDC sensor for that bank (since you've already changed the coils and rotators/dist parts). The other easy thing to try is to swap the connectors on the DigiPlex ECUs.

    If you do a search on "TDC sensor Digiplex" you should get many prior threads about this subject. Good Hunting!

    Jose;

    I'd need to check the car... but it does actually sound like an ignition/timing issue; did he check for spark on both banks? Is there a lot of fuel smell and random detonations on the muffler once the car is running?

    I'd really dive into the ignition/timing possible issues before even dreaming to touch anything injection-related.
