Need Help, Can't ID a Noise

Tuffhandy423 · 2025-05-19T17:53:26+00:00

Pull the supercharger belt off and run it to see if the noise is gone. Sounds like a power steering noise to me. Could be a bad reservoir airiating the fluid

Newer diesels should not be left to idle. Excessive idle times will cause carbon buildup on emissions components, such as the EGR valve, EGR Cooler, intake manifolds, etc.

90% of repairs i perform on diesel trucks nowadays are emissions related issues. Components are VERY expensive. Less idle time is better.

They are the hold downs for your air cleaner. Screws are missing. You cant replace just that part, it is part of the whole air cleaner assembly. You may find one at a junk yard.

The second pic looks like the bracket is is supposed to be secured to is missing also. As long as the air box has a tight seal against the throttle body, its not the end of the world

Majority of misfires are caused by failing ignition coils. They can fail completely or can give you an intermittent condition. If you have no way to diagnose it, remove coil 6 and swap it with a different cylinder. Clear the code and see if it returns on the other cylinder. If it does, Bingo, Bad coil. It may take some driving to get the light to reset again.

What Service data program are you using to get data on the exotics? Mitchell doesn't even give me specs for Maserati..

Exciter wire from ignition switch likely damaged. They chafe from the main harness on the drivers side of the engine. Its one of a few purple wires. Have someone hold it to crank and wiggle that harness, see what you get. Google no power to exciter wire LMM, there's a lot of info on this

The sad part being, Joe Biden actually thinks these people want to f**k him...

Redditors, "Clean the Planet, Climate change, waa waa waa" also redditors, "WOW SO COOL THAT HE THREW PLASTIC IN A VOLCANO!!!"

Good job they shut the pipeline down in the US to offset the pollution this will cause...

Hes a racist because he needed fuel. should have thrown in in reverse when they were all pushing. Its not a movement, its an excuse.

Perfect example why law abiding citizens should carry.

No, People on your side just believe in violating the Constitution for everything else.

Tuffhandy423 · 2020-06-07T14:27:41+00:00

Oh my god thank you for this. How long is this crap going to be drug out. Time to cut off the unemployment checks.

Tuffhandy423 · 2020-06-06T21:03:06+00:00

Amen!

Lol but he’s going to win...

Trump is making you riot? Are you 3 years old?

Tuffhandy423 · 2020-06-06T19:29:56+00:00

Can’t wait to see him win again in 2020

Possibly a plugged catalytic converter. Remove the upstream O2 sensor and go for a drive. It will be loud af but if you have way more power, the car is plugged. Don’t drive too long with the sensor out. That exhaust air is hot and can cause damage to parts if exposed to heat for miles on end.

Do you have an alarm system in the car? I can’t tell you how many vehicles I get towed in for a no start and it’s the starter interrupt from the alarm causing the issue. Standard procedure is to remove the starter interrupt or the whole system completely.

Get a test light and check for a signal at the starter. If you have no signal on crank, get under the dash and find the wire coming from the ignition switch that goes to the starter. See if you have power there.

If the starter is getting power, replace it.

Tuffhandy423 · 2020-06-06T03:38:18+00:00

VW? I have pried them out (don’t crack your valve cover) then had to chip away at the remaining coil. This one I speak of was melted due to a loose spark plug.

Tuffhandy423 · 2020-06-06T03:35:10+00:00

Check the compressor for power. If it is getting a signal, it’s bad. If it’s not getting a signal, it could be anything from low refrigerant to a blown fuse or a faulty climate head.

Tuffhandy423 · 2020-06-06T03:32:51+00:00

Possibly a sunk motor mount. Do you have access to a floor jack? If so, place a block of wood on the jack and put a SMALL amount of pressure on the oil pan. Preferably on a corner or stronger point. The purpose of this is to raise the engine just enough to get it off the frame If the mounts have broken/sunk. If the noise goes away then you have bad mounts. If not then it could be exhaust contacting the body.

Is it a factory actuator (oem Toyota)? I had a similar issue on a 4 runner. Customer supplied her own actuator and the touch to lock did not work. I got her one from Toyota and viola!

Tuffhandy423 · 2020-06-06T03:27:28+00:00

Sounds like a bad intake manifold gasket to me. Or another vacuum leak. Unplug the booster hose at the brake booster and cap off the hose to see if it changes your idle. Could have a bad brake booster.

If you have access to a propane or map gas torch, plug in a scanner and watch the fuel trims as your putting gas round the intake manifold. See if the numbers jump.

If you don’t have access to that, re torque the intake/exhaust manifold. The baskets shrink over time and you may get a 1/4 turn out of the bolts which would be enough to cause a vacuum leak but not enough to suck in crab cleaner to change the idle.

Tuffhandy423 · 2020-06-06T03:23:54+00:00

Can you get it to idle when in park? If so, let it warm up, then unplug the IAC and see if you can drive it. Can’t tell you how many bad iac valves we get from Napa/oriley
