Vacuum test for restricted exhaust
Posted 28 September 2003 - 12:01 PM
I'm finally back home so here it is:
Connect the gauge to the intake manifold (dowstream from the throttle).
«Run the engine at about 2500 rpm for about 15 seconds. If vacuum drops during the period and does not incrase when you close the throttle, you're almost certainly looking at a restricted exhaust.»
Hope that's not to late to help.
