Hey I am having an occasiona problem with my 93 LX, sometimes when I cruise and go to shift in to the next gear the rpms will stay at whatever they were when I pushed in the clutch. Its not a wot problem, just enough held so if you let off the throttle the engine doesnt "compression brake" it will kinda stay at the same speed. I am told it could be a tps sensor a a TB. the pdal feels alright and the TB is an Edelbrock/BBK 70 mm. SHould I lube the ends of the shaft that goes on the TB plate?
