Powerloss.... Options

[Remy]

Hey guys I've been having a lot of problems with my celi lately....sagging lights, nails in tires, keyed, smoking etc... now its getting to me my engine have been running worse by the min...it seems like its losing alot of power when I floor it, it doesn't go anywhere dunno whats wrong maybe its time to retire this motor I know 5s aren't strong but mines usually pick up better then this....I was thinking maybe bad fuel pump or bad injectors. When I slam on the gas (just testing the car) it seems to slowly pick up my 0-60 is prob in the 30s... any advice on this ?? I was gonna try some fuel injector cleaner see if that helps anything else you guys think I should try ??

very poor acceleration could be caused by a jumped tooth on the t-belt. you would notice very poor accel on the low end that seemed to be better when the revs got up higher. other things that could cause this, off the top of my head, kinked exhaust or badly clogged intake.
