bleh, 240sx problem...ngk spark plug gap on 89 240sx?

[comablack783]

i did a tune up(oil, filter, spark plugs) on my car like 2 weeks ago and its been running odd, like it feels slower, and im almost 99% sure it sucking up more gas, could this be do to improper gapping? whats the gap supposed to be set on NGK plugs for a 89 240sx (sohc)? i also put a lucas injector cleaner that that they recommend at advance discount, pretty pricy for its size. the reason i say im losing gas milage is because the last time i filled up i put in 13.7 gallons and the tripometer said 242 miles, filled up this week and put in 14.8 (almost empty) and i only got 209 miles?... ergh...

going to regap ASAP, will this fix my milage problem? or could that have been do to the injector treatment? it said 33% more gass milage blah blah blah... seems like its 33% less..ergh...

IIRC the ngk plugs should be pre-gapped, ive never gapped mine

FSM says to set the plugs at .039in - .043in. I think they come .044in out of the box.
