Car Sputtering?

Question

I have recently changed my wires, plugs, distributor cap, and rotor and my car still sputters.

I just put some fuel injector cleaner in my gas tank, but I usually do that at every oil change anyway.

My air intake hose has a hole that is covered by duct tape, but that has been there since before the recent sputtering.

The sputtering seems to happen after heavy rains and usually goes away. However my car does not seem like it is acclerating at full speed still.

ANY HELP!

'94 Ford Probe if that helps

Answer 1

try changing your gas filter,air filter and also clean out your throttle body.if it goes away after it quits raining,then the distributor or coil pack is drawing damp.i have a 88 olds and it does that after a rain,but quits when the motor warms up.

Answer 2

Sputtering can be caused by a lack of fuel reaching the combustion chambers. however, a vacuume leak can also cause a car to sputter. the easiest and most dangerous way to diagnose this is to spray a flamible aerosol (such as some electronic cleaner) around the vacuume lines and along the intakemanifold flanges, if there is a leak, the engine will suck it up and the engine will idle up, it may be a bad hose or intake manifold gasket.

do this with a friend, and a fire extinguisher, and dont spray the distributor or coil.

You may need to re-ask, providing vehicle description, and more detailed symptoms. Only during cold starts? At any engine speed? Problem festered to this level? or is intermittant , or happened suddenly? Under no load or while in gear? will happen more or same when going up hill? OK once warmed up or the same? Under hood means back-firing through intake manifold but only that symptom narrows it down to about a hundred or more things. Need more info to derive a more logical speculation. As a master auto technician, not being present with the vehicle, symptoms are essential in order to derive a speculated answer by means of logic and probabilities. If it's an asian car it is almost always the coil ignitor, especially if it is a honda or acura. Most vehicles go through two or three in a lifetime. If better when warmed up would indicate a fuel delivery problem, as engine need not require as rich of mixture when warmed up, thus would backfire less. If always the same, could indicate timing error in valve train or ignition or actually many other possibilities. I could go on for six feet down the page speculating. Lets get some more symptomatics so that we can narrow this down to hopefully one thing. Thanks

Answer 4

I have a 92 Ford probe once have a same problem you described, after i changed transmission filter and fluid look like it ran a lot better. try it and see filter,gasket and fluid won't cost you over $30.00.

Answer 5

try the fuel filter, then, pressure test the fuel rail, if they check out inspect the injectors for clogging. injector cleaner doesn't get everything out.

Answer 6

Try checking the fuel pump...
