My 1987 Wrangler YJ -4.2L 258 I6- Has no emission control system at all all the vaccum lines that go to it are plugged I don't even have a computer to go into my carburetor. I was wondering If I have to go buy the whole system (expensive) or is there some way of fixing it. I do have The CTO, The EGR Valve The PCV Valves and thats about it. i have a racing air cleaner on there so nothing except the pcv hose connects to it. I bought it this way. I was just wondering if theres any way I could live it like this but change it so it doesn't have a 2000RPM idle.
