I replaced my platinum spark plugs, which i changed about a 1000 miles ago, with some new iridium ones. I notice that there a lot of unburn fuel left on the tips of the old spark plugs. That not normal cause I just change those spark plugs only a 1000 miles ago, anyone have any idea what the problem?

 

Could be your FPR, get a guage and check your fuel pressure , it should be about 35 to 41 psi at idle, if that checks out , then your coil on your distr. could be dyin or your ignition timing is too retarded....

 

what did the plugs look like? and is it on all four cylinders?
