Re: Ruff Idle ,Huge Loss of Power
Changed out the fuel filter today . Gas that spilled out of it looked rusty . Also retested the amp draw on the fuel pumps , 8 amps now .
I also pulled the plugs and found one that was whitish . The others looked grey or slightly dark in color . The whitish plug was either number 5 or 7 . Also engine runs very smooth at 2000 + rpm but still has a rough idle . With the one plug looking off , is it ok to take the car out for an Italian tuneup or just a simple test drive ? From reading the manual and searching online , white means lean . I don't want to hole a piston . Thanks Mike Sent from my ASUS_X00PD using Tapatalk |

Re: Ruff Idle ,Huge Loss of Power
Had some fun today . Replaced both fuel pumps . Found out after installation that one of the pumps did not work . So removed the sender and tried both of the old pumps . I can get the sender in and out in under 5 minutes now . The old pump and the new pump are both reading 3 amp draw now ?
What givez ? Why am I reading 3 amps on the new pump ?  RockAuto is sending me a new pump . Sent from my ASUS_X00PD using Tapatalk |

Re: Ruff Idle ,Huge Loss of Power
Pull a few spark plugs and see if there are any specks of metal embedded in the ceramic (insulator) portion of the tip. If there is, that would confirm detonation.
If not, then although those cylinders may be running lean, u likely don’t have a danger of “holing” a piston.

Re: Ruff Idle ,Huge Loss of Power
Any idea where I can get a new float/plastic foam for the fuel level arm ? The one on our car is cracked and is absorbing fuel .
