I am having a problem and i am trying to figure out what is causing it i have a 89 Camaro 305 tbi lo3 and did not really know there was an issue until the other day. since i bought the car it has been very sluggish i thought 305s really are the dogs people say they are then the other day i cleaned the throttle body and vacuum lines by spraying in some brake cleaner took it for a drive and it ran like a different car it had a lot more torque the next day not so much back to diving like a 4 cylinder wondering if it could be base timing or electronic advance iv heard that maybe the timing is retarded and spraying brake cleaner in the throttle body temporarily bumped up the timing any ideas?
