Check your spark plugs for wear, and replace or inspect engine for vacuum leaks........with car running, spray some starter fluid around the engine.....if the engines rpms increase, you have a leak somewhere....typically in the hoses around the throttle body area..... its also.possible that the idle control valve is faulty or stuck in open position.......

Idles smooth, sputters coming from muffler like its running on one cylinder


Hi T:
Interesting as smooth idle and sputter are contra-indications.
- Smooth idle should be healthy
- Sputter could indicate problem:
- mis-fire? Possible bad spark plug or bad exhaust valve. Pull spark plugs to check to see if any are fouled. Compression check will help depermine why fouling is happening.
How many cylinders?
How many Km on engine?
With engine hot, Remove oil filler cap and see if any vapour indicating blow by (bad rings)
My suggestion?
Do some more checking and reply as a comment on this post. Will assist if I can.
Cheers.

I have a 2006 GMC Envoy, idles rough at a stop when in gear, but levels out smooth when in neutral. Drives smooth on the highway.


check for a vacuum leak in the brake booster. Check this by just allowing the engine to idle with the hand brake on and if ok then put your foot on the brake and if the idle changes then there is an air leak in the booster.

Rough idle smooth accleration


Check your vacuum lines and be sure your throttle body is tightened down. Carb cleaner spray can be used to find the leak. Spray it around the lines and gaskets (while the engine is running). If the idle speeds up, you found the area of the vacuum leak and the solution to your problem, possibly.

My car idles up the down; sounds like it wants to stall, but smooths out after a few minutes of warming up.


Its a faulty idle air control valve.You can take it off and clean it using a non-chlronated brake cleaner and a wire brush or and a scraperor you can replace it with a new one just make sure to reset the computer afterwards by disconnecting the ground cable on the battery for 30 seconds then start it.

Got a 99 Nissan Altima 2.4, t-chain broke... replaced head and all t-components... start up surging idle and whistling off idle... engine runs smooth and great power off idle


the surging and whistling sounds like there might be a vacuum leak that is causing this.recheck all vacuum lines and surfaces were this is a gasket that seals a vacuum source.smooth running and good power off idle suggest this leak only affects the motor at a low(idle)rpm.
