Jus wondered I've put about 20k on Paula and havent changed the filter.The hit the throttle and leaving two perfect 20 footers is gone can the filter be the problem,I know my throttle body needs a good cleaning just hit 73k this weekend, on the way back from Charlotte
I would clean the throttle body real good and the IAC pintle. You'd be surprised how that mellows out your base idle and improves throttle response. A fuel filter and air filter swap won't hurt, either.
