Hopefully some body can confirm my suspisions..... In the last couple of days my 88 Audi 90 s 2.3 5 cyl lost a dramatic amount of power.. the systems are this... If i press the gas pedal to the floor, i lose most of the power, I can slowly accel by slowly pressing the gas, but it requires i don't rev much over 3k rpm.... I have already done the following: Fuel filter/air filter changed... Tune up- plugs, wires, cap and rotor Checked timing... Cam, Crank and distributor are all timed correct Changed bad o2 sensor
My suspision is it is the fuel pump... does that sound like the next logical step? the only thing i have not done is try to adjust the mixture.. but that is for me to leave up to the pros..
Is there any way i can check the fuel pressure myself? i don't want to $200.00 or more on a new pump if i can avoid it.
Thanks for your assistance
