You need to have the engine codes pulled and if you have a p0420 code you most likly have a bad cat. but i need to know the code stored in the computer.

you developed a knock in the engine, sounds confusing but your engine computer can't separate bad bearing from pre-ignition, engine knock, to cure this your computer retards the spark, to the max to stop the knock, confuses the computer to the max

Rod knock upon start


Not sure on model but to me sounds like its a dodgey valve lifter when the seals start to go they cannot hold the oil and when there under pressure they basically empty them selves hence when you turn the engine off and restart you get a rattle sound untill the valve fills again as long as the cars running ok leave it untill you have to replace them unless there easy to do sone are sone are a pain

2004 explorer died while driving then won't start and sounds horrible shaking in engine. All lights and electric working. Little wrench light came on.


I dont know what the horibile shaking you are describing they seem to ussually just loose a fuel pump or a ignition module. If its a knock or grind it wont help you. if its metalic its a rod or timing chain. a rod or piston knocks and or rattles around timing chain grinds and or motor spins faster than ussual. Good Luck

Ok. Last night my car started making a knocking noise. Its not loud and only happens when im in idle. Also it seems to come from the bottom of the engine. Help?


if it gets louder and faster as the engine speed increases then a piston is knocking...if it is just at idle like you said then it could be a bad oil pump if oil light is on at idle or it could be the connecting rod knocking on the crankshaft because it is loose.

I don't know what engine you have. If it is the v6 then you probably have the death knock my v6 just did that last month! a new crate motor cost 1200$ and put it in your self.

Motor knocks when first started


It sounds like the lifters are draining down over night. When was the last time you changed the oil? A fresh oil change may do the trick, if not try some hydraulic lifter additive ( you just add to the engine oil)
