1997 Chevy Malibu Code P1441- Rough Idle

[budh420]

hi, i've been having a erratic idle with my 97 chevy malibu

I took it into my friends shop and he found the purge valve hoses were flipped, so he fixed it now when I run low on gas (gas light on,or fill up) I get a p1441 code and I never got it before. I was reading that with a faulty purge valve it can cause erratic idle but I was never getting any codes before he flipped the hoses, and I still have the erratic idle problem....

freeze fram data...

fuel sys 1 CL
fuel sys 2 NA
Calc Load (%) 7.84
ECT (F) 165
STFT B1 (%) -3.91
LTFT B1 (%) -2.34
MAP (inHg) 14.17
Eng RPM 1376
Veh Speed (mph) 31
MAF (1b/min) 1.57
TPS (%) 7.45

does anyone know what might be causing this and if it is releated to my erratic idle?

Thank You

A bang in the fuel tank is usually caused by high pressure or vacuum. This should be controlled by the purge valve. The code P1441- flow during non-purge may be gone, but something is still wrong. Maybe the other guy thought the hoses were worng and switched them, but they were actually correct to begin with- and the new purge valve fixed the light and code, but now switching the hoses caused this thunp noise. Depending on what hoses, you may have full engine vacuum going straight into the tank !

I checked my book and he has the hoses right, its not banging anymore it was just that one time but still has a irratic idle, im wondering if I can try and run the car with the gas cap off for a couple of minutes to see if it changes anything?
