70 MPH bucking problem
As far as I know it is the original pump. No I don't have a scan tool but a friend may have one and will check. Trying to not spend money where not needed (this new invention called a budget lol) and appreciate your input. Forgot about the sock on pump.- yrlessbob

70 MPH bucking problem
I was wondering if that was correct FP on the rail. Has stock 28 lb injectors and have been wondering about regulator, fuel pump, or bad injectors. Besides the bucking it will also die out for one to two seconds like running out of fuel.- yrlessbob

Brakes Problem - please help!
Chris, I have the issue with the brake light but have hard pedal. The AC Delco part number is 18M754 for the accumulator ball. Can't seem to find it using the AC Delco web site so stopping by store tomorrow to see what they can do for me.- yrlessbob

70 MPH bucking problem
I replaced it about a year ago right after I bought the car and old filter seemed fine. Have 28 lbs of fuel pressure on the fuel rail and I can't duplicate the problem in the shop.- yrlessbob

70 MPH bucking problem
Hello all, I have a pure stock 87 GN 54,000 mi with a couple of issues. At 70 mph and above it will start bucking and dying out like running out of fuel, slow down to 65 and runs like a champ. Under acceleration no problems, shifted out of OD to change RPM, problem still there. Doesn't do all...- yrlessbob
