You may have to do a fuel pressure test. Have you changed the fuel filter lately? Also, It is always good to do that during a tune up. The vehicle is a bit older, so you may have to go through and check some other systems in this situation. Did you move the distributor at all during your tune up, possibly putting the ignition timing off? There is a Vacuum Advance Unit on the distributor that controls ignition timing also. The running bad condition could be a few things, so we will have to narrow it down a little at first. Let us know what you find and we will keep checking this thing out so you can get it back on the road.
