So my issue has been a little bit of an ongoing one for a while and so far I've replaced the below list of parts due to various codes and misfiring issues etc when I first got the car along with general maintenance. Its all stock so nothing questionable done to it as far as I know!
Its a 2007 V6 4.0 5 speed manual and while driving my idle speed will sit at around 750 rpm for most of the time when I stop, but randomly it'll rev up to 2000rpm + when I'm at a stop sign or lights or when I push the clutch in before it settles back down again to a lower number. Sometimes if I've stopped somewhere and turned the car off then started it up again for the rest of that trip it behaves normally, so it does seem to be pretty intermittent!
When replacing the throttle body I ran through the idle relearn procedure from the manual as usual, and for that trip - a near 40 mile drive with speeds from 20mph - 70mph it ran perfectly so I was hoping it had settled down but two days later on a drive it started randomly revving again!
Any ideas on what I can try to solve this problem or has anyone noticed it on their 4.0?
Parts replaced:
Throttle Body
Battery
Spark Plugs
O2 Sensors
Leads
Coil Pack
TPS
EGR Valve
Fuel Filter
Oil & Filter
Air Filter
Hopefully there's someone out there who has had similar issues to this and can shed some light!
Thanks
