Hello, new to the forum so hello everyone!!! I am having some issues with a 06 acura csx 2.0l, automatic. There are no codes being thrown. Starting at cold start takes about 5 turns, shifting from park to reverse rpm spikes from 900 to 1500 for a couple seconds making it a rough shift. In drive stopping at a stop sign, idle drops momentarily like it almost wants to stall but does not. Greatly appreciate any insight. Things I've done to try to rectify, plugs, oil change, throttle body clean, new battery, purge vacuum solenoid. And checked pcv valve. I have checked for vacuum leaks to no avail but have not ruled it out as there are a lot of bloddy hoses in this model, lol.
