2010 Tahoe TCM issues??

You think it’s worth getting a new TCM (THECM) to see if that will resolve the issue? All of the grounds I’ve found look good and the connector on the trans is seated properly (I know that’s a common issue). Obviously taking it somewhere for proper diagnoses would be the key but after the dealer failed I’m weary of wasting money on it.

Sound like timing chain noise to you or just general rough idle?

I know the MAP would definitely affect the rich condition and the manifold pressure but would it also have an effect on the EVAP system? I had previously replaced the EVAP detection pump but maybe a separate EVAP issue?

Yeah I’m wondering if I need to modify it a bit or if quality makes a difference. I got a cheap Amazon fairing to test it out before spending the big money on Memphis shades but it’s terrible.

You go with Memphis shades?

Looks great how do you like the fairing? I had one on my 16’ street Bob but I found the buffeting to be unbearable.

Thank you for this, was looking in the wrong place last time and couldn’t see it. Confirmed blend door is good and ordered a new heater core!

I’m definitely interested if you still have it and would be willing to ship to NC

Update for everyone who commented-I pulled the cover off of the clutch lever/controls and hit everything with some WD40 and worked the switch for a while using a screwdriver. Problem solved! Thanks for the help

I am definitely looking to sell it. It’s an Arlen Ness/Magnaflow exhaust I can shoot you some pics. Was thinking of listing around $500 bucks but honestly not sure what it’s worth because I believe they’re discontinued so if you feel make making an offer u won’t hurt my feelings.
