hey i have a 87 v6 2.8l firebird and my engine is making a weird tapping/knocking noise when i start it and gets louder when i push on the gas does anyone know what this is?

 

Possibly a number of things.

It could be broken distributor components, a faulty emission system or a vacuum leak. Also check your ignition timing, carb adjustment and make sure you have the proper spark plugs for your engine and have correctly gapped them. Make sure there is no damage to the wiring, either.

 

Checked your oil level? Do you have oil pressure? Does the sound vary in frequncy with engine RPM?
