I have the 3.4L version Pontiact Torrent (base) with 195,000 miles on the ODO and have a slight miss at low idle (slight enough that it only trips a CEL P0301 under just the right conditions). At idle, the RPM's bounce anywhere from about 712 to 770 (and the needle dances around quite a bit). Acceleration is pretty good from a dead stop (I can chirp the tires). We just aquired the vehicle recently and I performed an extensive tune up on it (plugs, wires, throttle body removal and cleaning, PCV hoses cleaned, new water pump, new tensioner, belt, oil, filter, valve cover gaskets, etc). This is my daughter's car now (new driver) and am wanting to make it as safe and reliable as possible. I have a new ignition coil on order, and new evap purge vent solenoid (considering installing a new EGR valve since I know they can be problematic on these). Am half way through a tank of Regane All-in-one FI and combustion cleaner. I know the intake manifolds on these like to leak, as do the head gaskets (but these were both serviced under warranty early on in the life of the vehicle). I have no oil in coolant or viceversa. Will be running an intake decarbonization procedure on this soon. Looking for any insights into this low idle miss. Thanks in advance.
