Lets see, After changing the ig-mod,spark plugs/wires, fuel filter,cap/rotor and having the cats checked (ok) The motor will not maintain a steady RPM. If you try to hold it at say 2500 it will drop and fluctuate. It runs better now but its got some horsies in there that cant get out. The air bags are in the suspention.It has been lowered. Rides like crap! Someone said I might have an injector not working right. Any thoughts? Thank's
