fuel pressure bleed down
fuel pressure bleed down How long should fuel pressure remain in rail? I have a steady 60 psi at idle, after shut down I have 48 psi for 20 mins then drops to 0 slowly over the next hour. Normal? Should I worry about it?
was having random no or hard start problems. would take a few cranks to get it going. This only happened twice in a month's time. I changed the fuel filter and after pulling old filter found that it has something loose in it. Replaced it with new. Figured that may have been the problem. That was only a week ago. Decided to watch rail pressure last night to see if I had something else going on. Also have a random I would say "stutter" in idle. It throws NO codes. Ive had it many shops, even dealer and they tell me "no codes" and it feels normal to them....I've had this 2001 Z28 since 2013 and can't remember it always having a stutter. Has 180,000 miles and original factory injectors and O2 sensors.
