The cigar test has worked for me in 2 occasions in the past to find leaks in the DISA valve's seal and also in a hose that was under the air intake manifold.

Probably the holes causing the leaks in those two cases were large enough and maybe smaller ones would not be found with the cigar test? I am sure I am not adding a whole lot of PSI with it, and a proper machine would add the required amount of PSI so it would be more effective.

Check the basics first, plug, coil, compression etc. Let us know what happens after clearing codes and resetting adaptations.

smoke tester PSI ?

But WHAT is the required amount of PSI to apply? When I was researching "proper machines" to smoke test with, I found most came with a regulator limiting the pressure to about 1.5 PSI, like on the AutoLine Pro EVAP Smoke Machine Leak Tester – Shop Series https://www.amazon.com/gp/product/B0...e?ie=UTF8&th=1that I bought (after returning a similar, but defective clone I had previously ordered).

I tested using my Husky compressor set to 5 PSI, and later tried it set to 15 PSI (which did supply just a bit more smoke), but never found a leak. Maybe I could remove the tester's regulator to supply more smoke, but then I might overpower a seal or two, so I won't.

PS...Amazon has the tester I listed above for just $70 for Black Friday. I paid about $102 a year ago, and that was with an Amazon discount.

Ok, so far I have done the following:

1. exchanged coil one and coil two positions
2. cleaned the reusable air filter
3. cleared all the codes
4. cleared all the adaptations through INPA
5. configured the obdlink bluetooth to record all kinds of data for my test drive

I will drive around some and report what happens next.

I watched a couple of videos on compression tests, I'll need to rent/buy some gauges to do that.

Thank you all for your help so far! :-)

I honestly don't know. This video says to only apply 9 PSI...

Yeah, probably wise to not go over a single digit amount of PSI...
