So I went to a car meet today, did a total of maybe hour and a half driving. Everything was fine until we left from lunch, got in my car, and it began shaking. I only live down the road so I figure I try and get back there and have a look at it. Car has very little power and sounds like a subaru when driving, but it seems to run "fine" when engine breaking. So when I get home, I check the obvious things first, loose plugs, stuff like that. I remove all the plugs and all but the plug on cyl 3 makes the engine die. So I check to see if I have spark, I hold the plug wire to the valve cover and I get it to arc. I then remove the plug and inspect that, seems fine. So just in case I swap plugs with cyl one and plugs with 3 and 4 (changing them on the distrib as well) cyl 3 is still dead. So I then think maybe it’s not getting fuel. It feels like there is a pulse on the injector, it feels like the other 3. So this leaves me with what, a clogged injector, I really cannot think of what else it might be, Forgot to add, this is on a bone stock 93 KA. If anyone has any other ideas, feel free. I stripped one of the injector screws so I will have to wait till tomorrow in order to remove it.

check injectors with a dmm look for like 10-12 ohms also check compression on the cylinders
