Alright so I know this is a GP forum but I trust you guys on here more than any other forum. My dad has a 1999 Cadillac Eldorado that we've been having issues with for a long time. It seems to have a missfire but no codes and it stutters at WOT and is real low on power. I know these N*'s are legendary for blowing head gaskets. The car has 172,000 miles and my grandma owned it before my dad. The head gaskets have gone before and been replaced a while ago but i'm wondering if it hasn't happened again.. So basically to try to stop the missfire at idle and crappy acceleration I changed the fuel filter a few weeks ago. Seemed to help the miss and the stutter for a few days but it was still low on power and then got worse again. So today I went to go change the plugs and wires and noticed a puddle of antifreeze underneath it. I looked and the whole passenger side of the radiator is covered and its just dripping wet all over. So then I checked the oil out of curiosity and there was none.. literally none. I had just checked it a few days ago and I know these engines burn a bit but I find this hard to believe. Any input would be greatly appreciated. And sorry if this isn't the right section for this.
