I had the same issues. Changed plugs, wires, MAF sensor (previous owner had bought them prior to selling to me so I inherited it all just put it on), idle air control and adjusted the idle screw to stick to 750 or as close. So far so good.
Needs either the clear coat fixed or all new paint job....I'ma do the paint job. Thinking of putting in a short throw shifter. Got any particular you would recommend?
Gonna paint it a darker green next year. Rims stay, but tinting is on the horizon. Mines a 92. Everything works, alarm, new tires, new clutch. I think I got a deal considering everything that was done. Previous owner had everything done.
