Jeep Wrangler Emissions Diagram Q. Hello Vincent, This is the problem I'm having with my 1987 Jeep Wrangler. It has the 4.2 liter engine 5 speed transmission, A/C, P/S, and 150,000 miles. I'm getting oil in the air cleaner and a rough idle. Above idle it runs good. The motor doesn't smoke. I know I have some problems with vacuum hoses so I started replacing the hoses but can't find an emissions diagram for this year Jeep.

I even went to the Jeep dealer and they didn't have it. Could you help?

Thanks,
Bill
