I have a 89 Camaro l03 305 tbi the problem I am having is that it bogs down under sudden throttle increase and doesn't pull as hard as it should especially after 20mph I cleaned the throttle body and vacuum lines by spraying brake cleaner in them took it for a drive and it had a lot more torque the next day not so much back to diving like a 4 cylinder I am wondering if it could be base timing, electronic advance, egr or egr solenoid it has power down low idles good and drives fine other than the lack of power I mean I can floor it and its like it does nothing with the exception of the day I cleaned the tbi and vacuum lines I am at a loss

 

The first thing is that punctuation is your friend.

Check all your vacuum lines, make sure you don't have a vacuum leak somewhere. Make sure you have the proper fuel pressure (Should be 16-19psi with TBI). Replace your fuel filter and air filter.

Check your timing, make sure it's correct. Should be 6* BTDC or there abouts with the ECM disconnected (Four wire connector coming from the dizzy). Do a tune up, new plugs, plug wires, cap and rotor.

Double check the timing though, my number is from a Carbed car so it may not be entirely accurate for TBI.
