I also have this problem, new plugs and wires and still have a misfire. It just got worse and worse after a few days. If its the fuel injectors, is there any way to clean or repair them? And some times it gets slightly better, but still misfires, when i drive the car for a long time and get it hot.

Well since it is an 87 N/A, then I am also thinking it has a distributor with rotor and cap. It may be arcing between the 5 and 3 cylinders in the cap itself. Firing order 153624, so that is another area you may want to check. It seems to me you have eliminated just about everything else.
Good luck and let us know, Russ |

Yes, try a new cap and rotor, and check the fuel pressure. Any codes?
TPS and AFM can cause misfires too.

Im pretty sure it was a fuel problem, cause the car idled and revved up perfectly fine, it was just under load. But I put laquer thinner in my gas, and it runs fine now. But ive only had a little time to drive it, because I dont have insurance anymore lol.
