305 Engine Problems

[Low-N-Mean]

I have a 86 Pontiac Bonneville thats I bought form the original owner about a year ago. it sputters and rocks slighty when in idle but its a little more aggressive when I hit the accelerater. I've changed the sparkplugs, plug wires, fuel pump, fuel filter, Tpi sensor, and ignition coil.Someone help please!!!!!!!!

Whats a TPI sensor that can be used on an 86 bonneville? Have you changed the distributor cap and rotor? Sounds spark related...

I was thinking it's a fuel line it feel's like it's not getting gas

Have you checked the timing and looked for vacuum leaks? I have chased "idle" issues and found that they cause alot of issues when not fixed.

Well the original owner apparently didn't put the plug wires in the right firing order and Im afraid that messed something up.
