Have the vehicle scanned for error codes at autozone, its free. Post codes for more help....These engines have issues with the COPs (ignition coils-over-plugs) failing prior to 80k miles. When they fail typical problems are: Sputtering under load/acceleration, rough idle, random misfires, random stalling, light or heavy jerking under load (usually at 15-35mph and 45-65mph)..hopefully this helps!!

Rough idling and engine light flashjng on a 2009 kia berrego


A flashing check engine light means you have a catalyst damaging miss-fire. you will need to get the fault codes pulled so you can see what cylinder/cylinders are causing the problem. Once you have this information a diagnostic path can be determined.

Sputtering engine while in passing gear


At 150000 miles the plugs start to fail under hard acceleration the higher compression blows out the spark before it ignites the fuel. Random cylinder misfire causes the check engine light to come on. change the plugs!

2004 Ford Focus LX, was sputtering while driving


A flashing light is BAD. Its damaging the cat converter. I would check or replace the spark plug wires ( if all OK, then) replace the coil pack. I would not replace anything unless they test bad. but these car are known for bad coil packs.

Truck sputters and dies when you put it in drive or reverse.


Most Likely a vacume leak. Check the engine and surrounding engine bay for a loose hose. I would check the mass air sensor, make sure it is free of debries.
