got it fo cheap.........nice
i would do a full tune up. have u checked the oil at all. old people dont even know about oil changes. my neighbor went WAY OVER in her miles b4 an oil change and her civic still ran. when i say way i think it was like 15000. hopefully that oil its slug. could be injectors too...........hmm in 86 did they have injectors? it could be a fuel problem. change the filter on in. change the filters all around. if u can mabye change the filter in the tank. bet its the org.
GL, post a pic i dont even know what they look like!
