Driving my 79 245 stick the other day about 70 miles round trip. taking off at lights car starts to tug as I shift to compensate and get it rolling forward, once going at 25-30 or so it almost smooths out, then we stop at a light again and the process begins again! this began 6-9 months ago when the car sat for long periods and I wrote it off to bad gas, been thru several tanks and gas cleaner. almost feels like running on 2-3 cylinders!
