My smog pump was giving me issues (growling and causing a roughish idle) so I decided to bypass it with a smaller belt in case I may need it for emissions in the future.It ran the best it ever had after the bypass... BUT! After about 10 miles on the belt the idler pulley started to growl like a bear at idle! Does anyone know where I can find one of these darn things? It is the pulley attached to the alternator bracket and all the parts stores around here seem to only sell the other idler with the center bolt. Also, I have not really looked closely at it, but I have no clue how to get it off! Any help would be greatly appreciated.
