Got on the motor a bit this evening and at 3000RPM in 4th (3.73 AOD) car sounded and felt weird, almost like a miss but not quite the same. Well got home and checked the engine over and had black powder on the snout. Can pull plugs tomorrow and check if necessary but would slippage be that noticeable?
Oil pressure was 50PSI, Narrowband O2 said was fully rich, coolant temp was normal and car returned to normal once I let it get back down to about 2700.
