Question about Cars & Trucks

1 Answer

Clcking noise I have a problem with my 2008 Ford Escape. When I turn on engine I get a high rpm for about 15 seconds, 2000 rpms back to 500 rpms at idle. The thing that concerns me is the constant clicking noise that gets worse when I hit the gas. Also AC only works on high speed

I would need to listen to the "clicking" noise before I could even begin to help with that. As far as a high idle at start up, in many cases on a Ford if you have that problem you may have a vacuum leak. Your computer corrects the problem after start up so the vehicle runs correctly. Is your check engine light on ? Most cases, a vacuum leak will cause it to come on but would need the code to be sure. Now finally the A/C only working on high would mean that you most likely have a bad blower motor resistor. Very common symptom for a bad resistor. Could be the switch but doubt it. Hope this helps....

This sounds like the TPS. Thottle Position Sensor. This controls the idle. Your local Advance Auto Parts should have this part. It should not be that expensive.

F22a engine produces strange noise most obvious at 2000 rpm, what could the problem be?


Without a general description of what the noice sounds like, squeal as compared to knocking, it is impossible to help you. Engines make a lot of different noises, so try and help by describing noise. I would suspect it is belt related, or tension pulley related as these are RPM variable noises, belts tend to slip when you accelerate and can be quite loud with a serpentine belt as example.

2007 mustang gt have engine knock problem when going from 1st to 2nd gear at 5000 rpms?


5.000rpm's high revs and you run into problems with valve bounce ( hitting pistons) ,ring slap, gudgeon pin knock, big end noise and possible main bearing noise . You may also be getting a hydraulic lock in the hydraulic followers that is holding the valves open too long. Unless the engine has been specifically built for these rpm's any loose ,worn on unsuitable part will cause problems I am thinking that you have around 100.000 miles on the clock after 7 years and the motor is not young Ford V8 engines specifically built for a 500 klm race are limited to 5.500 rpms because they destroy the timing chain if driven over that speed .

2002 ford expedition rpm not right


DId the Check Engine light ever come on?? Normally with such a major problem the check engine light should of activated in which case you can take it to a Autozone or most auto parts stores adn they can plug a Code reader into your system download the codes/messages and it should pinpoint or at least point you in the correct direction as to what is causing your issues.
I have had to do that a couple times with my 2005 Chrysler T&C due to a O2 Issue, and a Catalytic convertor issue.

I have a 2008 Ford Escape, 3.0L V6. I just had a Super 40 flowmaster professionally installed today. I never tried revving my engine in neutral before, but I tried today so I could hear what the new...


Hello there,

This is a normal operation, all your doing is hitting the rev limiter. It's there to protect the engine from over revving. The Powertrain Control Module or PCM cuts fuel to the engine intermittently to keep the engine from revving past a predetermined RPM when in "neutral", and in "park" if it's an automatic. Just in case something like a foreign object or a small child or animal were to inadvertently depress the accelerator pedal and rev the engine too high and damage the engine in result. I hope this info helps, and just for peace of mind, I am a Master Certified Ford Technician. Enjoy your new exhaust!! I'm sure it sounds great!!

Loud clicking noise coming from engine when at high rpms. I have a stick. The noise happens just as I'm about to shift from 1st to 2nd, 2nd to 3rd, 3rd to 4th. Doesn't happen much in 4th gear or...


sounds like the rockers or lifters have some play due to wear.you don`t say what rpm you are shifting at other than high rpm.by changing the oil you have increased the viscosity of the oil as its new and not dirty and thin and cold oil is thicker than warm oil.you might want to try a heavier oil to see if it helps.you may not get this noise out unless you replace components or adjustment of rockers if they are adjustable.if its not very bad you may have to live with it.

Engine noise rattle at about 2500 rpm?


Is the oil level ok? I assume the car is still under warranty? If it is, don't drive it, as damage to the engine may result. Call the dealer and explain the problem and have it towed to them. If you drive it, they may try to get out of a warranty repair, saying you 'abused' the vehicle by driving it in this condition.
