guys
on my 75 truck 390, i have been wrestling with a BIG ignition problem! seems like when the motor heats up, it starts to miss and backfire BIG TIME out the exhaust. (sounds like a sniper with an auto rifle LOL) it got sooo bad tonight coming home from work that i honestly thought i would have blown my mufflers apart! i replaced the duraspark 'brain' with a new one but it didnt help any! they guy at the parts place told me that they (the rubber grommets on the brain)are color coded for certain applications---> the one i have is 'blue'? i saw 'green' ones too but arent they all the same? he said they ARENT! moreover, he said something about another module being bad which might cause this. before i kick out any more $ buying unnecessary parts, can u guys help? its a 75 F250 4x4with electronic igition. if i shut the truck off after a backfiring episode and wait a few, it runs OK but not wholly well. its only until it gets hot or i really work it, that it goes bonkers on me! i am clueless here. any ideas will be greatly appreciated! |
