So I just joined because I've been having an issue I can't diagnose and need some help....I also love reading posts on automotive forums.

Car was stumbling at all RPMs but after replacing fuel filter, rotor/cap, plugs, wires and coil....it's now stumbling at low RPMs but gets better once car is warm.

I'm thinking it needs a valve adjustment, which I've done before. Is this a common issue for 3.2s that are in need of a valve adj?

Thanks
