flattiefan Posted July 16, 2011 Report Share Posted July 16, 2011 Okay I sent my injectors off to get tested and they tested fine. Still have the bucking tho. Any suggestions as to what is wrong .... btw- have a new fuel tank, new fuel pump, new fuel filter throughout. Could it be the isc? timing? the injectors are almost brand new as well. is there a filter in the throttle body other than the net things, because they're fine.

psu_Crash Posted July 16, 2011 Report Share Posted July 16, 2011 When does it buck? If it runs fine until you get on it hard I would check ignition timing, vac advance, plugs and wires. Link to comment Share on other sites More sharing options...
flattiefan Posted July 17, 2011 Author Report Share Posted July 17, 2011 no actually it does better when i give it more gas. that's why we thought it was my injectors. Around 1500 to 2300 rpm it's awful. Link to comment Share on other sites More sharing options...
Indiana Posted July 18, 2011 Report Share Posted July 18, 2011 Tested, or cleaned? You might have a bad CTS or it hooked to the wrong connector or the clips just rotten. Did you test your vacuum advance? Did you replace the injector clips, cut the harness back to clean copper strands to attach to. Link to comment Share on other sites More sharing options...
