I have a 98 GC Laredo and every once and a while upon acceleration it wouldn't accelerate and it would putter a little and kinda pop a little sounding like a faint backfire from under the hood then it would go fine. It did this like twice a month or so. Then one day it started slower than normal and sputtered the whole time then wouldn't start again. I may have two problems, the not starting is do to a bad alternator since the battery is new and i suspected that the sputtering was a dirty fuel filter but it may be related to the alternator. Is you voltmeter low? Mine got about 1/2v lower evey week until it died completely
The Sputtering tends to be a old or clogged fuel filter the engine is getting starved of fuel replace that and it should fix the problem
YES. Bad fuel pump pressure can cause that problem too.
Probably the fuel filter. Change it.
It doesn't have a filter. There may be a screen under the wiper cowl on the passenger side. from momule: there is no improvement to this answer. this is correct and complete.
AnswerFuel Pump?Fuel Filter?Catalytic converter?Air filter?While all of the above will affect the engine speed performance, the sputtering or popping you are experiencing is caused by the oxygen sensor. It can cause this problem without causing a check engine light to come on.
If it is still sputtering, it is important that you take it to a mechanic to have it checked.It is possible that you did not change it well. Take it to a professional mechanic if you are not one.
I can't tell much from what you've described but it sure sounds like either a fuel filter or a failing fuel pump.
If a car is sputtering at low speeds when driving one thing it could be is a clogged fuel filter. Another possibility is the catalytic converter could need replaced.
Change fuel filter add a bottle of gas and injector treatments will
Have vehicle scanned to determine the problem-- Could be 1 cylinder not firing due to bad ignition coil or more serious problem
Change your oil one, sputtering could also be a clogged fuel filter have your vehicle serviced
clogged fuel filter, or bad fuel pump
Your air filter is probably clogged. Try cleaning or replacing it.
could be a vacuum leak
== == Fuel starvation. Check fuel filter for clogs, and check air filter for excessive dirt. Also need to check ignition timing and spark plug condition. In other words do a tune up on it.
It has been awhile since I owned a Chevy truck, but I seem to remember it was something to do with the vacuum hose or filter getting clogged with dirt. If you wait a few minutes, it should start back up. But, it is a faulty vacuum (filter), and needs to be replaced.
Start with changing the fuel filter at the right front of the fuel tank, underneath, in a recess.
Probably need a new Fuel Filter. When was last time it was changed?
Could be a fuel delivery problem like a plugged fuel filter.
Fuel supply problem, possible plugged fuel filter or fuel pump failure..
99% of the time its the fuel filter. These cars are 15+ yrs old, and the fuel filter is supposed to be changed every 36000 miles. I seriously doubt very many people can tell me the last time they had theirs changed or changed it. Its an easily overlooked yet critical part. I find this to be a common problem with sputtering and running poor, esp on high fuel demand such as putting pedal to the metal,etc.
Hey Richard==The fuel boils slightly when it stops circulating. No problem. GoodluckJoe There are air bubbles moving through the filter WHILE you're driving. It doesn't hurt anything.
I have a yellow flashing light on whilst driving looks like two eyes (two hoops) I think it is the diesel filter. What do I do to clear it
Assuming the fuel filter has also been replaced, a bad distributor cap and or wires and spark plugs could do that also.
