Hey All;
What is the best way to diagnose a vacuum leak? Here's my situation (and I certainly plan to investigate this further with a scan tool and the assistance of a local guru who does much of the work on my car). Just thought I could putter around with it myself in the meantime and maybe learn something.
I suspect, but can't be sure, that the leak could be coming from the plenum. The install of the RJC powerplate makes me think that I may have botched one of the gaskets on the plenum.
Is there a tell-tale way of diagnosinga vac leak? I don't see any black discharge on the lip of the plenum. I do get a tip-in stumble on the car after it's hot, but it's not terrible and it seems to come and go. I did get a code 44 for a couple of weeks after my 009's, TA51 and chip were done, but it went away about a week later and never showed up again. and it would only blow the code when it was idling in park (idle would suddenly change and the code would show up). As soon as it got throttle it would go away.
Car runs like a rocketship otherwise. But the presence of that code 44 still makes me curious. fyi - I run 105 RFG unleaded.
Lastly, since I'm now immersing myself in scantool technology (turbolink), is there something that I can look for that will give an indication of a possible vac leak?
Any thoughts?
combo is below:
