when i start my car up the engine sputters and when i hit 3,000 rpms it feels like the car loses power

i unhooked the battery terminal to reset the ecu

anyone know what this could be?

EDIT MARCH 10

so far i have changed


-spark plugs
-plug wires
-fuel filter
-cat convertor
-fuel injector cleaner
-89 octane gas from Sunoco (used to run 87)


anyone?

I had this problem with this with my old engine too. It turn out that i have oil in my spark plug from leading through the head gasket. Look at your spark plug

 

when was the last time u had a tune up? if it has been a while, try changing plugs. wires, rotor and cap

 

my uncle said maybe water in the gas?

 

It's your ignition coil. Either replace it with OEM or get an MSD BlasterII. Bam.

 

how much are they? <TABLE WIDTH="90%" CELLSPACING=0 CELLPADDING=0 ALIGN=CENTER><TR><TD>Quote, originally posted by Archidictus &raquo;</TD></TR><TR><TD CLASS="quote">It's your ignition coil. Either replace it with OEM or get an MSD BlasterII. Bam.</TD></TR></TABLE>

and to the other reply, it wasnt the spark plugs

 

water in the gas anyone?

i feel ya. my friends car is sputtering too... but really bad. it has its days where its fine, then the next it goes nuts and barely drives...... good luck...

 

it's got to be a bad coil or some bad gas ,try putting some higher octane fuel in it and see what happens

 

id have to go with fuel filter. Look at that first before almost anything else. If it hasnt been changed in over 30,000 miles, id go with that....makes all the diff in the world

Anything really could be a factor

 

thanks guys

i guess ill try the fuel filter and 89 octane gas before anything else

 

i changed

-plug wires
-spark plugs

still doing this sputtering to an extent

could it be a clogged cat convertor?

 

yes a plug catalytic converter can make the car sputter. also you might want to pull the cap off your dist. and see if there is any dust, debris, etc in there, if so blow it out and maybe whipe it down with a clean paper towel and see if that helps. kinda hard to say what your problem could be but i hope you figure it out

 

maybe bad fuel filter or dirty injectors

 

not bad but old

 

my car was sputtering today, and i found out it was because my car's been sitting for 2 weeks with old 87 octane. pumped 92 octane and it ran fine again.

 

i also replaced the fuel filter but it didnt do anything

should i run all the old gas out before i put 89 octane in?

 

to the top

 

someone has to know

 

Did you ever figure out the problem? I have the same problem, and know it is not: the gas, the clogged fuel lines, distributer cap, plugs, or wires... the timing is dead on. The only thing left is the ignition coil because it seems to be timing/ignition oriented. It could be the distributer itself but it is pretty new. Higher octane gas did make a difference. The car runs well when really cold (right after start up) but once it is warm, it sputters at start and at about 5 thousand on my D16a6. Help me from your experience.

 

I'd either say ignition coil or ignitor.
