ka running rough needs help

Alright well ever since I bought my car it has had this little problem. So I will go drive my car and say 30 mins to an hour later while the car is still hot if I drive it it will act up and start running on 3 . So i talked to my uncle whos a mechanic and he said its probably just old plug wires that pop off, replaced those and 40 bucks later its still doing it. Its not like it does it everyday just every once and awhile and it eventually goes away after driving it for like 10 mins. I have ruled out that its not a bad injector cause it would do it all the time and so im lead to believe it may be some kind of wiring problem. What do you guys think ?

replaced cap/rotor while doing spark plugs?

id say check the injectors neway.. its common for them to seem ok then loose continuity at running temp if bad.. if not then yeah probably wiring

Nope probably should and I will take a look at the injectors

you may know this allready but you dont have to remove the injectors just unplug the harness and test them with an ohm meter , dont qoute me on this youll probably wanna look in the fsm but im pretty sure they should be in the range of 20-24 ohms hot (running temp)
either way the numbers should be realitively the same across the board when hot with a variance of no more than 6 ohms
