‘85 fiero sport 4 cylinder (Page 1/1)

Ok. I’ve got a ‘85 stock 4 cylinder. Eveyhthing seems to run great but when I put it in reverse, it seems to run a little rough. I know it’s old but it only has 59,000 miles on it. Now I did change the plugs and wires and still no change. I didn’t change the cap and rotor and the pcv valve yet because I ran out of time. Also I did change the air filter if that matters. Now when I did change one of the plugs there was oil on the ground electrode and my buddy says it’s probably because I have a valve cover leak and it was seeping in or it seeped in when we took the plug out.🤷‍♂️
If somebody could shed some light on what could be causing it to be a little rough when in reverse I’d certainly appreciate it.
Thanks!!!
