No throttle response after oil & filter change - any ideas?

[cyclerambler]

Recently acquired a 2014 RTL @ 27kmi and decided to do my own oil/filters work. Changed HCM and fuel filters and oil.
put it back together and it starts fine but there is no throttle response...I've taken it back apart and no sign of wire/plug
issues (didnt touch any but thought it worth a check).
Is this something the BUDS gizmo at the dealer should fix or is there something I'm missing that others have experienced

Thanks
Tom

You didnt hit the throttle body actuator when removing the oil filter?

[cyclerambler]

I didnt remove the oil filter...the PO changed the oil/filter about 800 mi back so I just changed the oil (after most of the original oil ended up
on the garage floor during the HCM filter replacement). I may have bumped the actuator so I'll have a close look whilst I have the tupperware
off....tnx

One more thing I'm noticing is that once started the idle is about 1000....if I gently twist the throttle
I can get it to peak at 1400 then it immediately drops back to 1000. Not sure how informative that is....

Ok...still getting informed of the data on the digital indicator panel...it appears to be showing
Transmission Control Module component malfunction cause....doesnt sound good

I wonder if you need to hook up BUDS and prime the HCM. Most dont but it your case you may have to.?? Sounds like your in LIMP mode??

You pulled any codes?

How can I find the codes? Do I need BUDS for that?

Great...thanks...the codes are:

P07B1
P0934

Thanks...the first one seems basic but I just did the oil and hcm filter change.....also changed the fuel filter...maybe I buggered something up there...will check.

Found a connector that was loose...now only P07B1

Well good luck and hope you find the issue. I know some have put oil in the new HCM filter too. Not sure if this would help in anyway.. Still may need to purge the air but just guessing at this time.

Thanks for your help...greatly appreciated...
Is there another way, besides Buds, to purge the air?

[Joel The Biker]

try putting it in gear while its idling. Foot on brake. Maybe it will move some fluid around? Not sure what else to try

Thanks Joel...well I'll be danged!!! Started it up...put in reverse, foot on brake, parking brake off...slowly revved...felt like it wanted to take off
so put it in neutral and twisted the throttle and it spooled way up!!! Kawabunga! Things are looking up!

Thanks
Tom

Glad it worked!!!!!!!

Must have pushed that pocket thru and got the oil moving again.

Every time I've changed my oil and filter, including at the 56K service when I changed the HCM filter, after I removed both plugs and oil drained from the crankcase/dry sump and cutch cover, when I loosened the seal on the oil filter cap I heard the sound of additional oil draining out of the clutch cover plug hole. Since cyclerambler only drained the oil but apparently did not break the seal of the oil filter canister that may be where some air got into the system and caused the engine not to spool up. Putting the engine in gear probably got oil circulating in the appropriate parts of the engine and purged the system of air pockets. Just my guess.
