You will need to first pull the code fron your car's ECM (computer) before we can determine why your Check Engine Light is on. Once we know the code we can determine why your car is not accelerating fully, The code and the accelerating problem are all related, You can go to your local AutoZone store and they will be able to hook up a OBD II scanner to your car to find out the Trouble Code for your problem for free. Once you have the code your Mechanic or you can properly diagnose the problem and replace the part that is causing the accelerating issue that you have.

Engine misses when you excelerate. when its hot engine wont start


It could be to much air, not enough fuel. Or to much fuel, not enough air. Most likely the first, unless you notice a lot of black smoke when accelerating. Check engine light on? Also could be the catalytic converter/s. Have the codes read. repost.

I am sputtering up hills and loosing power with hard exceleration.


Hi joel , a few things to look at : Do you have a Engine management light staying on after the engine has taken ? , if so you will have to get a proper diagnostics test done , your onboard computer has the ability to store intermittent glitch information and produce a code which will point you in the direction of the problem.

No malfunction indicator lamp showing : make sure there is in fact a light showing when the ignition is turned on .

Now observe the condition of your primary and secondary circuit , check the wire connections at the coil or each coil depending on the application , check all other wiring leading to and from any sensor on the engine .

Air filter inspection clean or replacement . Check the condition of the spark plugs (if you have a lean burn white electrode)

Your condition described points a lot in the direction of low fuel pressure , have the fuel pump pressure checked out and replace the fuel filter.

I have a 1996 chevy 5.7 vortec engine idles high at 1000 and when you open throttle fully it has like a misfire no power


This could be anything from a bad vacuum leak to bad ignition coil to spark plug wires to distributor cap and rotor or ignition coil. From the sound of this I would look to the vacuum leak or the EGR.

When excelerating my car starts to **** until I get to a steady speed then it runs just fine. I've already replaced the filters but the garage still can't find anything wrong. Thanks for your help.


Is the check engine or service engine soon light illuminated? If so, what trouble codes were found.
Per your description it sounds as though you may have an engine missfire condition in from the ignition system.
Is this a 4 cylinder or 6 cylinder engine.
Good luck

Failed exceleration, engine jerks when driving, Added engine treatment with last trip to gas station and that didn't help, Now, the check engine light has come on.


Check pcv hose from the intake manifold for collapsing and leaking. Check while engine is running if it is leaking it will cause the light to come on. Also a dirty air flow sensor will cause a lack of power. Check ign coil for cracks along the sides also.

2003 buick century under fast exceleration the engine light will flash then go away,if driving easier no trouble@aol.com


Hello Rocky.

Sounds like it's time for a tune up or an ignition diagnostic.
The check engine light flashing is indicating an engine misfire.
This could be most commonly caused by a bad spark plug, bad ignition wires, bad ignition coil, bad fuel injector.
If the spark plugs have black streaks down the outside of them, replace the ignition wire set as well. This was a very common problem with these models.
Thank you for using FixYa.

I feel a tug (stutter) when i excelerate , i had a tune up and the injectors clean... still there what now


replace all the ignition coils, this vehicle is known for ignition coil failure. Typical symtoms include: jerks when accellerating, jerks on light-heavy loads, misfire, stalls, check engine light. These coils usually last up to 80k miles.

Engine light blinking


You may have a bad spark plug wire or plug, if that doesnt solve the problem it could be the ignition coil.
