1983 Chevy G20 throttle/stutter problem.
Hey, forum. I'd was happy to find this site. I recently purchased a 1983 G20 converted by Get-Away. It drove really well except when I would punch the gas. It would not accelerate, only generate some popping noises like air was getting in somewhere it should not. (this still happens - air pops out of the air filter.) Then, after getting it smogged, I was driving uphill to a friend's and it began to stutter. I quickly stopped, pulled over, got directions to my friend's mechanic and rolled downhill in neutral into the shop.
The mechanic has checked the ignition module (works fine) and he confirmed the timing is set correctly, too.
Any ideas? It idles perfectly and rolls in drive and reverse while in gear. Then, giving it gas, it seems the timing is off/it misfires/stutters/etc.
Fuel filter? 99% of all the tubes were replaced recently, though the few that haven't been look pretty brittle.
Any thoughts/ideas would be well-appreciated.
All the best!

Thanks for your response. The problem has been resolved.
The mechanic looked at a few things off the bat: ignition module, fuel pump, and timing. All items checked out.
He then checked the timing chain and said it was well within tolerance and wouldn't be the issue.
Pardon my layman terms - inside the distributer, there are flaps that he said could stick sometimes or not operate correctly. He replaced the entire distributer for $160.
Now, I can floor the accelerator and there are no popping noises. The van now just ZOOMS. It also turns over much fast in the lower gears and doesn't rev as high in 1st and 2nd. Does all that seem to fit?
Happy it's running well and he didn't charge much for labor. My pocket's pretty happy about that.
