1987 Audi 5000 gauge problems

[Eric Huppert]

Ok so drove to work again this morning and ran the codes...no codes still. The car is now bucking when I get into the boost and gauges are still going nuts. I don't hear the engine reving so I don't think its my clutch going @ all. The car is idleing very low now aswell. Still very stumped to what it could be since there are no codes after cleaning the rpm and tdc sensors...guess I need to check the grounds tonight when I get off of work. There is only 3 of them in the engine bay correct?
