my car sputters sometimes at 1800 rpms around 40-60mph for the past 2 mos. thing is its so infrequent that when i take it to the dealership service to check and scan codes, it doesn't happen. i've been twice and nothing. no codes, no sputter. they told me to come back when it happens more frequently. today my car sputtered with the a/c on at around 2500rmpsfrom 60-90 mph. that was the first of the sputtering at a higher rpm! i dont know what to do. im worried. should i continue to wait till this happens frequently like the service center recommended? is this bad? is it bad to wait till it happens more frequently. thanks all.

 

My car does this infrequently. I found that cleaning off the MAF sensor with some electrical cleaner, "carefully" wiping the elements with a q-tip does the trick until it gets dirty again...I think some unfiltered air seeping past my lid, as the screen always has junk on it when I check.

 

Check/ clean the MAF like the man said above. Also Check / change the fuel filter.

 

wll do. thanks
