maxinDixon 11-03-2008, 11:43 AM I sometimes have a rolling idle and I think it has to do with the EGR system. When I disconnect the vacuum line to the diaphragm on the intake, it straightens out. I have 6 inches of vacuum at this point. What is the expected vacuum one should see on this system? I wonder if my pump is on the way out. maxinDixon 11-03-2008, 07:37 PM It amazes me how much a faulty EGR solenoid can upset the balance rates and create a loppy idle. Cost me 32 bux to replace the solenoid that sits right above the fuel filter housing. Was leaking pretty bad causing the EGR valve and the intake butterfly valve to pulsate in and out. No wonder my idle was loppy and my balance rates were erratic. The balance rates are now steady as a rock and have even improved.

EFI is something I am contemplating. nolimit2403 01-03-2009, 11:43 PM *** nolimit2403 01-03-2009, 11:44 PM What?? nolimit2403 01-03-2009, 11:44 PM OOPS wrong one | ||
