Hey guys .

Need some suggestions.
I went to clean my TB in the my 997.1 TT because I noticed the idle was higher then usual where I couldnt read my oil level , cars been sitting for almost a year plus it wasn't driven much prior well I put it all back together did the TB relearn , started it and it had a really choppy idle but once the fuel closed loop it sorted it self out back to a high idle ( 950-1000rpm) . Took it for a cruise and it misfired . Came back home,plugged the durametric to find some steady misfire when i restarted it .
I am going to smoke test it after the long weekend but also considering changing the TB gasket cause the plenum and the TB had some black gunk that wiped off.

Any suggestions and tips are appreciated

UPDATE .. gasket changed nothing changed, leaning towards camshaft sensors x4.
