my car is running rough at idle and when i start going from a stop but once it gets going the problem goes away. i changed all the spark plugs and wires and one of the spark plugs was molded together. after a day of driving on it the plug turned black in the same cylender and it runs rough again. anyone have an idea of what the problem is?

 

Sounds like that cylinder is running a little rich could be a leaky injector any codes

 

i didn't check for codes yet i only have a tester for 96 and later i gotta get the one for my car. i was thinking it might be running rich i was also thinking it could be a valve spring or something like that. il have to see what codes trip and find out from then

 

You can always swap that injector with one of the other ones and see if the problem follows

 

While you're under the hood it wouldnt be a bad idea to check your fuel pressure

 

fuel pressure is fine because the car runs great once i hit 40 the injector is a good idea tho il try changing it i feel like the car is running really rich and burning the sparkplug
