Possibly a vacuum leak, check vehicle emission system, or air intake system. In over 50 years of driving and working on all kinds of vehicles, I have several times seen this symptom caused by various kinds of RESTRICTIONS [or blockages] in the EXHAUST SYSTEM. Some examples of causes found include: blocked catalytic converters, tailpipes bent from backing over an obstruction, exhaust pipes or tail pipes "pinched" from collision damage, and separated/collapsed bulkheads inside of mufflers. There are other causes, but these are all I can think of at the moment.j3h.

Where is fuel filter on 1988 Pontiac Bonneville?

The fuel filter on the 1988 Pontiac Bonneville that I have is located on the drivers side, tucked just under the body of the car and in front of the rear tire well. There are three lines coming from the tank, and one of them will go to the metal cased fuel filter and connect with a metal hose fitting. It will require two wrenches to remove, one for the fitting, and one as a backup on the fuel filter. The filter is against the body of the vehicle and there is not much space to work within.
