My 1994 Z28 Camaro runs fine but after 10 minutes or so of driving it seems to drive really sluggish and sputter when i press on the gas would be my transmission maybe fuel problems?

The symptoms you describe – sluggish performance and sputtering after about 10 minutes of driving – point more towards a heat-related issue than a transmission problem. While a failing transmission *could* cause sluggishness, the sudden onset after a period of warming up strongly suggests something is heating up and malfunctioning.

Here are the most likely culprits:

* Fuel pump: A fuel pump that's weakening with heat could be delivering insufficient fuel under load after it's warmed up. This is a very common cause of this type of problem.

* Fuel pressure regulator: Similar to the fuel pump, a failing fuel pressure regulator might not maintain proper pressure once it gets hot.

* Mass airflow sensor (MAF): A failing MAF sensor can give inaccurate readings, especially when it gets hot, leading to a lean fuel mixture and poor performance.

* Ignition system: Heat can affect ignition components like ignition coils or wires. A failing coil might misfire more frequently once it's heated up.

* Coolant temperature sensor: An inaccurate coolant temperature sensor can cause the engine computer to adjust fuel delivery incorrectly.

It's unlikely to be a transmission problem because transmission issues typically manifest as slipping, hard shifting, or complete failure, not a sudden loss of power after a warm-up period.

Troubleshooting Steps:

1. Check your fuel pressure: This requires a fuel pressure gauge. Compare the reading at cold start and after the car has been running for 10 minutes. A significant drop in pressure points to a fuel pump or regulator problem.

2. Inspect the fuel pump relay: Make sure it's clicking correctly when the ignition is turned on.

3. Check for vacuum leaks: A large vacuum leak could cause poor performance, but this is usually noticeable even when the engine is cold.

4. Scan the OBD-II system: While your 1994 Z28 might not have a fully OBD-II compliant system, it might have some diagnostic codes. A scan tool can help identify any potential issues.

5. Check the MAF sensor: This often involves cleaning it with MAF sensor cleaner (follow instructions carefully) or replacing it.

Important Note: Ignoring this issue could lead to more serious damage. It's best to get it diagnosed by a mechanic, especially if you're not comfortable working on the car yourself. The potential for damage to your engine's internal components is high if the fuel system isn't providing adequate fuel.
