Jeep Wrangler TJ – Rough Idle/Vapor Lock (Heat Soak) CHEAP FIX

Описание: If your 2000-2001 Jeep 4.0 engine has problems in the heat and it idles rough or hesitates, it is most likely a heat soak related issue.

Supposedly there was a recall for the 4.0's from 2000-2001 because the exhaust manifold gave off so much heat that it was vaporizing injector 3 and causing a misfire, which leads to rough idle, hesitation, and poor performance. If you ever run your Jeep for a while, park it in a parking lot, come back out, start it up and it runs rough, that is heat soak. After cooling down for 20 or so minutes, it may go away. This method will prevent that rough idle from ever happening.

The fix for this is relatively simple, cheap, and effective. There are several ways to fix this problem, but for me I bought a $50 heat shield kit from Amazon which completely removed the issue for me. Another excellent option is having a hood louver as it allows heat to escape quicker, however for me, I needed the heat shield as well.
