i went back to the al plugs, but my car cut out once again today so maybe the problem isn't fixed? it just weird that i was drive down the road and it dies and then doesn't want to start back up? until sitting for a minute....to be more in detail i found out the car bogs down and then dies....also i replaced the fuel fliter las night and some how i am now getting 20 mpg when it use to be aroung 22 mpg any reason that could be happening? and also is there a common problem with the end of the spark plug wires breaking off...i mean the tip inside the boot comes off? i had a cavlier and it had that problem and i didn't know if these cars do or not
