I have a 1988 Chevrolet Sprint - Non-Turbo/Carbureted
The problem I am having is that the car Sputters/Misses/Bogs or however you want to describe it
It feels like it misses when i start to get to a higher RPM (cant say how high because the vehicle has no tachometer)
I was having a similar problem in the winter while driving up the mountain
But we resolved the problem (or delayed it) by cleaning the points on the distributor cap
My immediate reaction was to Replace the distributor cap and rotor
Also replaced the spark plugs and wires but the problem still persists
We also cleaned the fuel filter
When decreasing the timing by adjusting the distributor the problem seemed to occur quicker
Our suspect parts are distributor and fuel pump
But are also wondering about any vacuum pods that could be causing the problem
Anyone have any ideas why this could be occurring?

You don't clean the fuel filter, you replace it with new.
Put the timing back to spec and get the codes read. Post them here, and get a fuel pressure reading letting us know what that is while this is occuring.
Check for vacuum leaks closely. This car is old enough to be drinking in a bar and I would change every inch of vacuum line as protocol. If it doesn't fix this problem it will prevent the next one. Line is cheap and easy to change.

Wow a Chevy Sprint. The car that is ranked third in fuel efficiency. I'd love to have one as a puddle jumper.
Since we volunteer our time and knowledge, we ask for you to please follow up when a problem is resolved.

Well i can go replace the filter which i probably will once this is fixed but it is not that
We checked the fuel pump and we were getting 4 psi of pressure out of it so that means the fuel pump is running fine
We checked the timing and it seems to be in time and the belt looks good
We were checking for vacuum and we are unable to get any vacuum from most of the vacuum lines
So i guess we will try checking out the vacuum lines and maybe one or some of them are clogged up
The PCV valve is working properly so that rules that out

Don't waste the time to check them, just replace with new. Costs almost dirt to do so and if the vac advance line is collapsed it certainly shows that was the issue.

Glad to hear it worked out and a cheap fix on top of it. Thanks for posting the fix too as you won't believe how many people look at these posts even years down the road to see what helped others in a similar situation.
