Does it sound like the engine? Can you localize it at all to the front or back, left or right? Does it seem to match the speed - knocks faster the faster you go?

What is code p0325 on 98 accord


Code 325 is for a knock sensor failure.
The sensor looks for spark knock and if that happens the engine computer slows down spark timing.
The problem could be the sensor, the wiring, or something other than spark knock the sensor is finding. A bad valve or rod knock can mirror the spark knock traits.

Metallic knocking coming from from under hood when pulling away.


I'd guess that its related to the double gearbox removal. There are four engine/transmission mounts: one on the top side of the engine, one on the top of the transmission, and two on the center member. One or more might be loose or separating. The top engine mount is a common problem. Could also be loose sway bar mounts, or strut bolts on the uprights.

Check your front sprocket for missing teeth. I have broken all of them off and it would only slip at times making a horrible sound and I have also had every other tooth go missing. This is all due to a wore out chain. You need to check you chain for wear by pulling it away from the rear sprocket. If you can pull it away from the sprocket and see a fair amount of space between the teeth, replace the chain. Also both sprockets at the same time. Repost another question if more problems

97dakota 3.9 have a bad knock,pulled a injector off guit knocking, is injector bad


Is it an engine knock if it is an engine knock and killing the cylinder by removing spark or fuel makes it go away then your injector is in fact working. The reason the noise quiets down its because you've eliminated that which would cause a load or pressure in that cylinder. This means you have some worn internal engine parts.

A knocking that starts when engine is cranked then it goes away


The knock is likely a worn connecting rod bearing. Are you using the correct weight of oil, never use any heavier than 10W30W, heavy oil viscosity's cause slow circulation through the oil passages and starve the engine's bearings for oil.

I have an '01/'02 Grand Cherokee Laradeo, when I slow down the oil pressure drops to zero, when I accelerate it goes back up. There is a quiet knock as well, this just started happening. Pleas


If there was no noise when it went to zero I would replace the sending unit by the oil filter for a few dollars. If it is a light ticking and it is all the time I would replace the bad lifter but if it is more clanking or thumping you have problems. If you disconnect one plug wire at a time and run it for a few seconds and the noise goes away that cylinder has a bad connecting rod bearing. I would pull the oil pan and replace the bearing. Or just replace crank and connecting rod bearings and get rid of it

Is it true that a damaged knock sensor can slow down or make the car lose power while going uphill? Toyota Corolla VE 98


Yes it can. The knock sensor retards the timing due to irregular levels of octane in todays gasoline, to eliminate or reduce what is called a spark knock. A malfunction could cause your car to lose power when car is under a load or uphill due to pre detonation or constantly retarded spark to the engine. If not replaced it can cause engine damage or head gasket damage. Hope this helps.

The knock sounds like right under the driver side and mainly happens when your slowing down


Might check your brake disc(rust, end of the pad) and/or check if your tires are unbalanced at the mentioned speed. Unbalanced tires might cause knock/vibrating
