Hi guys, I have a bit of an issue with my 95 5.0 that I need some help with. Here goes! It will slowly develop a rough idle if it is allowed to sit and idle for a few minutes and it seems to load up. There will be a slight smell of fuel but it will fire right back up. It will also rev to around 3K when the clutch is pushed in during gear changes going down the road. It seems like whenever the load is taken off the engine it will rev. The AIC is nearly brand new as is the MAF. The plenum, throttle body and AIC gaskets are new. It has new vacuum lines and the one way valve in the vacuum line with the sensor is new. Any ideas? I need help! Thanks!
