Primary injectors are not working properly?

You could try and clean them?

Any other suggestions?

Hey Bro:

I have a 88 convertible NA that has the EXACT same sounding problem. Whenever I am just crusiing down the road somewhere around 2500 rpm the car bucks about once or twice every minute, but continues running ok. Have you had any luck solving this? I am going to put new plugs, wires, filter, and all new cats in later this week. I will post if I have any luck.

turns out the tps was out of adjustment. and the timing was out.

Any chance you could pst or link the method you used for adjusting the TPS and timing? I have that gactory manual and it says to use some wierd checker light for the TPS...
