    So warm or cold, then not likely the ECT sensor.

    Another quick question...Does your tach stay working/steady during the breaking up or is fluttering like someone is turning it on/off? When my PIP was on its way out, it would literally drop the ignition and tach signal, which would very quickly drop the tack to '0' and back up as if I was shutting the ignition key off. And it was also temperature sensitive where it would work cold, but 'die' when it would warm up and heat soak. Could also be the TFI, which you could put you 'old' TFI onto the new dizzy to test that theory.

    This is not a perfect video but it is of my SVO with a new Walbro Fuel Pump. If yours is not similar to this than your pump nds to be replaced. You need to check under boost and accelerating.

    coil has been replaced also

    will be doing a computer swap(with a known working unit) today to rule that out.

    Swapped computers and that did not change anything

    ordered a TFI connector that should be in later today (more fun for tomorrow)

    If that is how the TFI connector looks then you may just likely have some other connector issues elsewhere in that engine compartment, I hate to say. Now comes the fun of starting to go through and looking at all the other various connectors. Have you tried to pull codes to see if they will give you any sense of direction where to start??

    I was having similar problems with my 85.5. Turns out the ignition timing was set to 5 deg BTDC. I changed it back to where it belongs (10 deg BTDC) and no more high RPM stumbling.

    you can do it with a analog (or digital with beep) ammeter.

    seems like it might be worth a shot!

    VERIFIED..................

    All 4 injectors are stuck.................car started and ran with starting fluid

    after it ran for a bit I could get it to start on its own with no starting fluid

    (would take it a bit to start on its own but started up with a rough idle but then would even out and idle smooth)

    Yes I do................

    Bought the injectors from RC Injection back in the 97-98.

    payed a premium for them and have never had a problem with them till now

    I guess they where made before the Ethanol blended gas.

    will have them cleaned and rebuilt by next spring(car is being put in storage for the winter.

    at least the saga is over............... or to be continued next year

    I prefer the first option..

    The factory injectors were made before methanol-blended gas. Letting pump gas sit in the tank for extended periods of time will muck up the fuel system, even with a stabilizer. While the car is in storage would probably be a great time to get the injectors cleaned.
