i have a sohc that had some bogging/hesitation and i was burning rich. i too cleaned the maf, tb, did timing, full tune-up, new fuel hoses, new fuel filter, new fuel rail and i got somewhat better results. however, i still had issues, then i had all the fuel injectors cleaned and calibrated, and no more hesitation.

rc engineering(rceng.com) did the injector cleaning and in their report it was noted that before they cleaned them that only one of my injectors had good spray, while the other 3 were dripping and ALL were below their flow rates. this was obviously why i was hesitating, burning rich, and getting lousy gas mileage. i paid $96 to clean/calibrate all 4 and i got them back in 2 days. their service also includes new injector filter, o ring and insulator.
