89 lb9. it's got fresh plugs and wires, all hooked up correctly. the miss is only occasionally. just kinda putters at idle sometimes. runs fine while driving it though. it's got a relatively fresh MAF. the dizzy cap and rotor are msd, but i noticed that i couldn't secure the passenger side very well. like it's a little loose.

could it be an injector that's not pulsing correctly? and do you think running something like seafoam through the tank would help?

 

nobody has a clue eh?

 

Try a balance test and see if you can isolate it to a single cylinder. If not, I wouldn't worry about it too much.

 

how would i do this balance test? carbs are so much simpler, lol! but i will not let this tpi system beat me. i love the way it looks and this little stock 305 is pretty bad honestly
