Well to update you on my "project" car my 96 Bird....the car is currently in the transmission shop getting a total rebuild with all new parts, new torque converter, shift kit as well as a new core plug for the back of the drivers side head. Quote from the shop is 1500-2000. Before the car went to the shop I was getting a cyl#3 miss and it would turn the engine light on every so often. It has brand new plugs wires(motorcraft). I have yet to replace the fuel filter, coil packs, and clean the maf. When removing the cyl #3 plug the plug was covered in oil, so I installed an oil fouler into the cyl that helped keep the plug out of the chamber. What Im getting at is what could make this misfire occur between 600-1200rpm? It doesnt misfire above that and there doesnt seem to be any loss in power during the rpm spand, its just when at idle at a traffic light(in drive which you can really notice it) or in park which it doesnt seem as bad. Just after you start it you can smell the burning of oil out the pipe but after a little while it seems to go totally away or just about all the way. Any ideas to what this might be? I thought maybe a valve stem seal since these cars were known for them going bad in earlier years but it was supposed to be fixed for the 96-97 model years, but from what i have heard was that they can still go out on occasion. But someone said it could be a bad valve guide? What are the symptoms of this? It seems to be getting progressively worse(just added another half quart of oil which means its burning about a quart every 1000 miles) Does the oil leaking in the chamber do anything to it? Does it ruin the cats? Im hoping its just the valve seal but who knows....I will keep everyone updated on progress on the car. also I forgot to add that the car pings alot when put under a load but when you floor it, it goes away and thats with 87 or 89 gas.
