z3r0n3 Posted March 28, 2008 Share Posted March 28, 2008 my 240 was running just fine a few days ago, but then it started missing a beat every once in a while. it's been getting progressivly worse until today it finally died as i was pulling into a parking spot. Yesterday I put new ngk sparks (gapped at 36) new fuel filter, new oil filter, and 5 fresh new quarts of castrol gtx. The only thing i can think of is perhaps the spark lines or perhaps 5 quarts was too much? I don't really know but its running rough and i don't want to go anywhere in her yet. Thanks for the help Quote Link to comment Share on other sites More sharing options...
z3r0n3 Posted March 29, 2008 Author Share Posted March 29, 2008 also forgot to mention that it's a L26 block with the round 240z SU's just corrected the oil, same problem. Quote Link to comment Share on other sites More sharing options...
JSM Posted March 29, 2008 Share Posted March 29, 2008 Hold are your Dist. Cap and Rotor? Electronic Ignition or points? Points could easily do this and so could a bad cap or rotor. Quote Link to comment Share on other sites More sharing options...
