Hey guys,
for the last month i have been driving around with a twisted fuel line. Would that make the rpm's dive up and down and stall at times? It onyl does it sometimes, mostly in stop and go traffic. When it does happen the SES light comes on and it usually drops in rpms or stalls. Would it be the twisted fuel line, or could it be that the o2 sensors have never been changed? How can i test the o2 sensors?
Thanks guys
Dan

 

I would correct the twisted fuel line, this would restrict fuel flow if it's in the feed line and raise your fuel pressure if it's in the return line. Get your SES code read to determine why you're throwing a code.
