Need advise on knocking and stuttering!
OK, so I'm driving in this morning after letting the old girl warm up. She is an 81 cj7 with a 4 banger.
After about 15 minutes at 55 mph, she starts loudly knocking and stuttering like she's not getting enough gas. I pull over, and it all goes away. The rest of the drive in she's perfectly happy.
I turn her off, and after 15 minutes she won't start. Starter is engaging, just won't turn over (as in no fuel)?
Oil pressure is good, temp is good. Oil level is fine. Put in new fuel filter 2 months ago.
What ya think? Water in the tank? Has new plugs as well.
Any help will be greatly appreciated!
Also has new thermostat.
