Hello, have you checked the ignition timing with a timing light? These older 300 engines are well known for jumping a few teeth on the timing gears when they get older. They usually strip the fiber camshaft gear out. Thansk
Yes I have set the timing with a timing light. I can turn the distributor to the right and left and it works and I can set the timing but I still have a steady miss. Right now I am wondering if it could have anything to do with the vaccum because I can get everything set just right, put back together and it runs fine till I put it into gear.
Hello, I just noticed the question says that it has new points? Is this a 1985 or has the ignition system been changed? I have seen a weak ignition coil cause this before. Also how much did the distributor have to be turned to get the timing right?
Sorry it has no points
Someone please HELP ME I have no hair left .../??? I have no money left well just A little bit left ..
How much did you have to turn the distributor to reset the timing? Was it more than 2 degrees off?
Also, disconnect the vacuum line to the egr valve and see if it changes the missing.
Let me know. Thanks
Yes I did disconnect the vac. line .
Did it make any difference in the way it runs? Have you checked the manifold vacuum with a gauge?
Did you have to turn the distributor to get the timing correct? Are you using a timing light or are you just turning the distributor? Also, have you checked for any vacuum leaks with carb spray or a leak detector?
