my car has the same problem as this, 3 months ago i changed the plugs and all. but it ran fine then. for the past 3 weeks its been a pain in my ass. it wont rev up like it used to in gear. at first i thought it was the tranny. but im sure its the engine. some times i get a thud that comes from the intake. i asked terry. he said it might be a sticking ISC valve. im gonna clean that as soon as i find it. but i put some water remover in my gas tank and that helped a bit. but the problem still exist, im going to change my fuel filter which is what terry recommended after i told him the water remover helped alittle bit. but now it seems the problem is to to what it was 3 days ago.
Experience is the worst teacher; it gives the test before presenting the lesson.
