resurection Posted April 5, 2008 Report Share Posted April 5, 2008 I have a 96' Dodge 1500 with a 360, and 192K miles. I keep fouling spark plugs about every 2-4000 miles. Don't matter what kind of plug I use. Its all stock except for pullies and an Air raid intake. I keep up with mechanically, but I get tired of changing spark plugs all of the time, and having to deal with a miss. For the most part, its one particular cylinder, but after a while, all of the spark plugs do it. I've changed cap, rotor, wires, and plugs all of the time. Intake leak? Ignition related? Weak fuel pump or bad regulator? Ideas? Quote Link to comment Share on other sites More sharing options...
Guest 614Streets Posted April 5, 2008 Report Share Posted April 5, 2008 Is that 192 k on the original o2 sensor? That and spray carb cleaner around the intake to check for a leak. Quote Link to comment Share on other sites More sharing options...
Dave1647545494 Posted April 7, 2008 Report Share Posted April 7, 2008 check for vacum leaks, bad fpr, ect sensor out of range ( it can read as low as -40 and not set a code ) Quote Link to comment Share on other sites More sharing options...
verse Posted April 7, 2008 Report Share Posted April 7, 2008 Bad ECT is a good recommendation. Quote Link to comment Share on other sites More sharing options...
resurection Posted April 10, 2008 Author Report Share Posted April 10, 2008 Is that 192 k on the original o2 sensor? That and spray carb cleaner around the intake to check for a leak. O2's have maybe 30k on them. I was thinking fuel pump, or fpr. Quote Link to comment Share on other sites More sharing options...
