Have you replaced the IAC (idle air control) valve? That is a classic symptom of one that is bad. Is it throwing any codes? Is the check engine light on? If so, you might get the codes read and see what it is. I'm strongly leaning towards the IAC valve though. However, its difficult to tell on here a lot of times with such little details and not being able to listen and look at the vehicle. Well, anyways, good luck and I hope you get it figured out.
It could be a problem with the model. Try looking up the model and year it was manufactured on Google or Bing. Otherwise there's something wrong with the "coherence?" of you vehicles machanics because of trauma. Whatever it is Good luck!
Hi the whole subject about cars is based on one factor wear. When cars are new the metal surfaces are raw the actions of use produce wear. This wear eventually reduces the power out put so much so that by the time it reaches it's 8th birthday even if maintained with oil changes and oil filter changes the modern car engine is at the end of t's working life. Hence why event extended warranty companies will no longer support further cover.
Depending on which engine you have (which you didn't bother to tell us), it can be caused by a bad IAC, or a hole in the PCV hose.
Check and adjust your minium idle air rate…
clean the throttle body and plate area…
- My radio won't stop scanning, doesn't stop on any station, why? It's a stock 93 Ford Taurus radio, only am fm and cassette, cassettes work but I don't want to use. How can I get my radio to work again? My antennae was loose but I tightened it but it still won't work!
- Changed heater control valve AND panel and still only hot air? It's a ford ka… Was blowing hot air out air con when switched off. So changed the valve and worked for a day then back to normal… Changed the panel (2nd known problem) and that hasn't worked? When my engine is off… I can get cold air?
- I bought an Actron CP9125 Code Reader to try and diagnose a rough idle at cold start on a 98 Ford 4.0 engine. The rough idle had not caused? The CEL to come on. I plugged the code reader in with just the key on and pressed read and the little asterisk goes half-way across the screen one time and stops. I press the read button again and it reads 0 codes. I was thinking it would scan multiple times to check for pending codes or other issues. I tried it with the engine running and the same thing happens. Is this code reader operating properly?
- Why is my 2009 ford flex shaking after spark plugs were changed? After doing a tune up on my 2009 ford flex, the car started shaking and the AC does not cool. What could be the problem? I used OE motorcraft spark plugs
