Sounds like engine knock. Could be crankshaft or piston arm sleeves

This can be a sound made by "cam phaser" engines that Ford made for 4 or 5 years. Usually the noise quits above 2000 rpm as the phasers limit out in their travel. These engines are very sensitive to the correct weight oil being used and a Ford filter being installed.

The noise has been described as a muffled diesel rattle. Owners report stalling, hesitation, poor acceleration, but most do experience vibrations. What is happening is each bank of cylinders is suppose to be synchronized by the phasers. Imagine if half of the valves are firing several degrees earlier or later than the other half of the engine. Since these adjustments constantly change it makes trouble shooting difficult.

Other areas for rattles are the beads in the catalytic converters which may loosen and float inside the converter or even loose baffles in honeycomb design converters.

I have had terrible noises coming from gravel and rocks trapped in between the heat shields of catalytic converters especially if you travel gravel roads. Since you have "knock sensors" you can get driveability problems from the engine trying to misinterpete the knocks and rattles caused by rocks.

Air inlet or outlet may be clogged, check air filter and catalytic converter, as possibles!

code p 0432 is main cat converter bank 2 --efficiency below threshold ===causes -- cat converter---wiring heated oxygen sensor (HO2S ) in the bank 2 manifold before the cat converter
ave a compression test done to determine inlet valve seat insert loose
if you have a problem with it there should be a bit of a miss, or it should change with rpm
could be a cam lobe failing and the noise should change with rpm

Bang on the catalytic converter being careful not to get burnt and see if it's loose causing a rattle. Until you determind what the problem is don't drive the vehicle. The other possibility is that you may need an engine. If what you're hearing us a connecting rid knock.

well, without hearing the noise myself, i could guess that the torque converter clutch might be going bad. the torque converter is the part that transfers the power from the engine to the transmission via viscous fluid motion, the converter also has a clutch that internally provides a direct connection inside the converter for better fuel economy. but as with anything labeled as a clutch, it wears down to a point where is slips. the noise your hear could be the torque converter clutch slipping. i owned a 90 astro van with the same drivetrain that made a noise similar to what you speak of up hills. while driving up hills, fully depress the accelerator and if the clunking noise occurs, then the whine goes away as you accelerate faster in a lower gear, very likely this is the case. you would have to have a transmission shop diagnose further. i drove that old van for five more years cause i didn't want to pay to have transmission repaired. it can be very expensive.

sounds more like spark knock?

you did not specify in your ad what year or engine size of your vehicle but I'll assuming that timing is not adjustable

Therefore, the spark knock, assuming it isn't because of timing is likely caused from hot spots in your combustion chamber

Most shops have a decent method for cleaning for less than $100

keep us posted

Sounds like one or more of your fuel injectors is stuck open and dumping raw gas into the exhaust system. I would replace all the injectors since there was sugar run through it.

u may have throwen a push rod,which will cause a lifter 2 tick..or u may have blown out ur catalistic converter if u have one which is loss of power..
