help guys i have this really annoying problem. sometimes my car will turn over but will not start. There is a squeaky noise that comes from the (cap and rotor) part of the distributor. what is it? its annoying and it comes on once in awhile. can someone please help me diagnose this problem? i have a b20 with b16 head. b20 vtec. everything was fine until the squeaky distributor problem

 

pull the cap and see if it needs to be replaced. really need more info/pics to access the problem
