[QUOTE="condorf, post: 439032, member: 21153"] i have a 95 2.5l auto with 104k miles. Ive replaced the fuel pump,fuel pressure regulator and just today a new fuel filter. The filer was absolutely terrifying looking when i cut it open. I just got it up and running after sitting for about 7 years and it ran great for about 50 or 60 miles then suddenly it sounds like its missfiring/popping and kind of chugging with loss of power and idling rough. When its first started up after sitting for a day or two its fine but soon as i start to drive some it goes to crap at around 3k rpms and runs awful untill its sitting for a while, if i stomp it, it does power through and seem to run better and just slightly pressing the pedal its not as bad. I cleaned the throttle body good and replaced the gasket when it was off. My only other guesses are badly clogged injectors, maybe something left in the tank that got sucked up into the new pump, throttle position sensor, intake sensor also. The cat is original and could be completely stopped up as well, i drilled 4 small holes and beat around on it today after the fuel filter and it didnt seem to do anything. The chain of events go new fuel pump and regulator, driving for around 50 miles then the issue came up, cleaned the intake and new gasket and new fuel filter. This thing is running me crazy because its so close to running great and i feel like its something im just not getting looking for. Any info or tips are appreciated. [/QUOTE]
