I've been skeptical if there is some vacuum leak since the warm idle still goes up and down about ±50～100.
So I covered the air inlet on the air cleaner housing completely but the engine was still running as if nothing happened. Does this mean there is a huge air leak or is it designed to breath the air from somewhere else???? Thanks in advance (IMG:style_emoticons/default/pray.gif) |

Hello Ron, Thanks for the advise. I'll follow your guidance but...some questions came up.
1.) Expansion hoses on the plenum to runners >Mines are new but I did not put clamps on them. I can feel by touching the air outlets on the plenum and intake runners are not perfectly aligned so the hoses may be stressed and leaked. Better to use the the clamps? 2.) Crack in the plenum >What's the easiest way to inspect the dusty plenum? Just carb spray on them? 3.) Runner to head spacer/gasket >I installed new one while ago but I did not use gasket sealer or anything on either side. Is this causing the air leak? 4.) Throttle body gasket >It looked tired so I cut a gasket paper and replaced today but no change. 5.) Any number of defective hoses that connect directly to the plenum >They are all new but I will triple check and get back here. Thanks (IMG:style_emoticons/default/pray.gif) |
