RPM Revving issue
My 99 Wrangler 4.0 started having RPM issues about a month ago. Sporadically the RMP's jump way up for a while then go back down to normal idle RPM. It happens when sitting at a light in drive and also if it is in park, just idling. It often revs way up when i put it in park after stopping. Thoughts?
A vacuum leak is often responsible for high rpms, has anyone worked on or around the intake manifold lately?
Gone on vacation until August 25.
When you have a choice, buy American made.
