What kind of sound? tinny metallic or knocking? possibly have some very loose exhaust heat shields. reclamping or tack-welding usually does the trick.

Driving along makes a very loud noise like motor is racing, but continue driving, noise goes away then starts again???


Please take a look at your Engine's RPMs when this is happening and let us know, as it will help with the diagnosis. If the Engine RPM is stable (not high during the periods of the racing engine sound), then it sounds like your Radiator Fan clutch may be going out. The noise you are hearing is the fan kicking in and blowing a lot of air, which in turn sounds like the engine is racing.

If the RPMs are increasing with the racing engine sound, it could be the transmission/(clutch if manual trans) slipping.
Hope this helps!

I set my trucks RPM on a low setting, from inside, no engine tampering. Now it is warmer. My truck is still running at a low RPM, seems too low for current temperature. How can I adjust my RPM?


how did you adjust a pre-programmed ECU idle settings ??? please be more specific

the vehicle's ECU is pre-programmed to run higher than 1000 rpms while in "open loop mode" then idle back down to ~750 rpms once the engine reaches operating temperature "closed loop mode"

did you tap into the OBD 2 port and used a laptop to change the settings?

How do i get rid of engine code 13


Tony, take the new belt off and start over. You've not set the valve timing properly. Get the #1 piston up to top dead center on compression stroke first. Now remove the belt and get the crankshaft in proper position, THEN put the belt back on NOT moving the crank or cam pully when applying the tensioner. Before you put the covers and other stuff back on and in your way of sight, turn the engine over 360 degrees and see if the marks come back to proper position. Should be good now. Put the accessories back on and done.

1997 acura cl 2.2 revs up to 1500 rpm and down to 1000 rpm just several seconds after start


Cars are design to run at a higher idle at start up to warm them up quick. There is a sensor that reads water temperature and tells your car's computer how fast to idle. Your RPMs seem slightly high but not out of the norm. Does idle ever drop to around 600/800 after about a minute? If not, your engine temperature sensor maybe defective.

Nothing, you have hit the rev limiter. The up and down is the computer controlling the rpm. If you drive it, it should rev past 3,000. The computer is designed to keep free wheeling rpm to that level. It will only allow a higher rpm if vehicle is in gear and moving with a load.

My Audi A4 2009 makes a rattling noise on cold starts which resolves in less than 30 seconds. Dealer says its an air pump. This doesn't seem correct. The noise comes from the front of the care. Does not...


READ THIS (happy ending so far...):
audi a4 2L turbo quattro, manual transmission with 98,000 KM. Perfect conditions, no oil leaks whatsoever.

Left the car off for two weeks in very cold weather (-10C down to -25C). When I restarted, it started immediately but with heavy rattling noise due to camshaft adjuster not getting enough oil pressure. After 3 minutes of warming up (outside temp.: -12C) at very low rpm (below 2,000rpm), I start moving the car. Still hearing heavy rattle noise. As soon as I pass 2,000 rpm, I get a scary red warning, low oil pressure. Turn off the engine immediately. In 1 minute, I re-start the car and the engine lights check ok, so I drive in first gear super slow (1,200rpm) hearing the same rattling noise. After another minute, finally the noise all the sudden disappears and the car starts running just fine.

Called Audi dealer and they told me that in extreme weather conditions, I should warm the engine for 10-15 minutes if necessary before start moving.
Take away: luckily, I didn't screw up the engine since I was using it at extremely low rpm (easy to do with clutch and manual transmission) until the oil reached full pressure. I am pretty sure now that the problem was leaving the car off for such a long time in freezing weather. All the oil flows back to the bottom, and when I restarted it, the cold oil with high viscosity took a long time to reach all the parts of the engine, specially the camshaft adjusters that are actuated by using oil pressure. Next day, the car started at -9C perfectly without making any noise (as usual). Basically, the longer you leave your audi in cold weather, the longer you might hear the rattling noise until the oil reach full pressure inside the engine. My car took 6 minutes to fix it after couple of weeks in cold weather. This makes sense to me; in fact, in the past I only heard the rattling noise after leaving the car off for a couple of days in the winter.
So far, this has had an happy ending....

98 lincoln navigator loud noise, shaking, high rpm at idle, drive


I don't know how much oil you had to put in but it sounds like you have maybe more than opne issue and both sound major. One is engine reving and speed not picking up sounds like trans problem. Two the engine shaking and making noise and being run low on oil leans toward possible engine damage. If your mechanicly inclined check all fluids and when checking trans fluid smell it. If it smells burnt the trans has been damaged. Check oil pressure and make sure coolant is full.You may have to take it into the shop.

Sounds like a vacuum leak. Check all vacuum hoses on the intake, throttle body, etc. Sounds like one cracked or came off. Post back if you have any questions. Hope this helps.
