So I took my car out for a drive and started hearing popping from my pipes. Is this a good thing or bad? They don't pop when the car is idleing just when I rev up the engine.
Just revving in neutral/ park with no load on the engine? If it's on deceleration or engine braking that can be caused by exhaust manifold leak
If it's popping from the exhaust it probably meens one or more cylinders are misfiring. Could just be a spark plug that fails under load.
It doesn't pop when it starts, or when the engine is warming up. It's only popping when I have been driving for a about 20 mins.
New plugs and wires were installed. New manifold gaskets installed. New starter, alternater, and the carabutor was just rebuild a few days ago.
Do you have points, engine 350-455??? if so check the dwell 28-30 deg's, make sure the contacts are not burnt, voltage with points closed should be 5-5.5 volts, then reset timing to spec. The coil could be breaking down when hot, so check the resistance, primary 1.28- 1.42 and secondary 7200-9500. Also make sure your distributor shaft bearing in not worn out, check vac advance and advance weights are working properly. Good Luck! sounds like electrical problem.:TU:
