First off before anyone asks, the mods on this car are listed in the signature block below.... Now for the problem.
When I first start the car in the morning, cold, it idles perfect. After driving for a bit and warming it up, the idle starts to get a little rough. Almost like there is a miss. Once the car is up to running temp, it lobes really bad, and the wideband gauge goes from reading around 14-15 (with lobes around 16-17), to off the charts over 18, and idling super rough. Not bad enough to make it want to die, but it sounds like some of the old school muscle cars at a drag strip. I have brand new plugs, wires. I figure it needs a good tuning with an SAFC or something else to straighten out the A/F ratio.....any ideas?
