my 87 tII has a slight boging issue when i hit 3000rpms but it doesn't bog when i accelerate or deccelerate only when the pedel is barely down,im thinking it might be my secondary fuel injectors but im not sure any idears ?

 

you may be on the right track. if so, try a wide band o2 on it...

 

A couple of thoughts for you to consider...
- In the future, don't title your threads like you did this one. You'll get more help if you use a descriptive title instead of I need help.
- What you've described could be nothing more than an out of adjustment TPS. The TPS is sending its signal to the ECU at part throttle and decel. Make sure the TPS is correctly adjusted to 1 volt at warm engine idle. Then go and set the idle speed to 750. Make sure you short the Initial set connector before you make these adjustments. I'd do this before I start worrying about injectors.

Now, if your injectors haven't been cleaned in a long time, you might want to do that too. IMHO
