OK, I need help. I was driving relatively low speed when I hear what sounds like a gear grinding, it was really quick and then gone, and then I lose power. It accelerates but seems to be firing only on two cylinders.
WHAT JUST HAPPENED? I am so bummed as i just got this car back running with the FI. Any one have a super cheap Engine close that I can get to install this weekend? |

It seems odd that it should hapopen all at once. Were you doing anything unusual when it happened?
My first guess is that you mentioned that you just got it running. Did it sit for a while? Perhaps something is blocking the fuel rail on the dead side. This doesn't explain the grinding sound though. John |

My first guess is that you mentioned that you just got it running. Did it sit for a while? Perhaps something is blocking the fuel rail on the dead side. This doesn't explain the grinding sound though. John Just got it running maybe three weeks ago after sitting for about a month. The sound was strange. It was short, load and ended quick. It was like I ginded going into a gear but i was just cruzing at 25mph at maybe 2500rpm or 3k. Then it lost power. I was able to barely get it home. It idles but slowly and removing cylinder wires identified that Cylinder 1 n 2 are not firing but I haven't been able to do much more with it yet. I let it idle and listened for any mechanical but it seems to turn fine just not firing. If it is the Distributor some how, then I don't have a spare. If it's just spark plugs then I can get those. What if one Side of the trigger points were to go? would that create this condition? |

QUOTE What if one Side of the trigger points were to go? would that create this condition? See post #11 The noise is what disturbs me. What, that could cause this, would make a loud mechanical noise when it went out? Sounds like something broke, and that would probably cause damage you could see if you could get your eyes & hands on it. |
