1. Fuel System:
* Fuel Filter: A clogged fuel filter restricts fuel flow, causing poor acceleration. This is a relatively inexpensive and easy part to replace. Start here.
* Fuel Pump: A weak fuel pump can't supply enough fuel under load. This often manifests as hesitation or lack of power under acceleration. You might hear a change in the fuel pump's noise when you turn the key on (should run for a few seconds before the engine cranks).
* Fuel Injectors: Clogged or faulty injectors can prevent proper fuel delivery. This requires testing or professional diagnosis as it's more involved.
* Fuel Pressure Regulator: A faulty regulator might not maintain the correct fuel pressure, leading to poor performance. This needs testing with a fuel pressure gauge.
2. Ignition System:
* Spark Plugs and Wires: Worn or fouled spark plugs and damaged wires can lead to misfires, causing rough running and poor acceleration. Inspect these visually and consider replacing them as a preventative measure.
* Ignition Coil: A failing ignition coil can prevent proper spark delivery to one or more cylinders. This is less likely to cause the exact symptoms you describe but it's worth considering.
* Crankshaft Position Sensor (CKP) or Cam Position Sensor (CMP): These sensors tell the engine's computer the position of the crankshaft and camshaft. If faulty, the fuel injection timing will be off. A bad sensor can lead to poor running or even a no-start condition.
3. Transmission:
* Transmission Issues (Automatic): If it's an automatic transmission, a problem with the torque converter, transmission fluid, or internal components can cause it to slip or not shift properly. This would explain the high RPMs at low speed. Check the transmission fluid level and condition. Low or burnt fluid is a bad sign. A professional transmission inspection may be necessary.
4. Other Possibilities:
* Mass Airflow Sensor (MAF): A dirty or faulty MAF sensor provides incorrect readings to the engine computer, leading to poor fuel mixture and performance. Cleaning or replacing it can be helpful.
* Throttle Position Sensor (TPS): A faulty TPS gives inaccurate readings of the throttle position to the engine computer.
* Exhaust System Restriction: A severely clogged catalytic converter or exhaust system can restrict exhaust flow and reduce engine power.
Troubleshooting Steps:
1. Check the easiest things first: Fuel filter, spark plugs, and wires.
2. Check for any diagnostic trouble codes (DTCs): Use an OBD-II scanner to see if the car is storing any codes. This can give clues to the problem area.
3. Check transmission fluid: Level and condition.
4. Listen for unusual noises: Any unusual sounds from the engine or transmission could point to a mechanical problem.
Recommendation: Unless you have significant mechanical experience, it's best to take your Camaro to a qualified mechanic for diagnosis. The problem could be relatively simple (fuel filter) or more complex (transmission issue). A proper diagnosis will save you time, money, and frustration. Describing the symptoms precisely to the mechanic (high RPMs at low speed, jerking acceleration) will help them pinpoint the issue faster.
