Hello from France i did change the two big vacuum hoses since then i have a real bad MPG (grey smoke on acceleration and 1200- 1600 rpm on neutral). i found a small hose that come from under the gearbox (passenger side), burned on the exhaust pipe, but i don't find where to plug the upper( U form) part. Any idea? 92 V8 Bernard Larriu bernard at larriu.com
