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

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.

If it's doesn't sound like it's your engine which i am thinking not. Check to see if there any heat shield that may have come lose, like the heat shield to the spark plug wire or heat sheild along the down pipe. 
Good luck and hope this was the rattling your taking about as it heats up it expands and tighten's up.

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)
