so i rebuilt my engine 1480 miles ago an it started out great fast an loving it. the other day i was crusing around it was awsome shut the car off an started it up about 30 mins later an it had a crazy hard hesistation at about 3500 4000 rpm. i started thinking that maybe its my compression broke a apex. Checked the compression still good an even almost 7 on my gauge give or take. i reused housing and rotors so im not really worried about getting full compresson.

I checked almost everything changed my o2 readjusted my tps to 1volt changed my water thermo sensor. Still doing it, i dont have emissions so if i do a check engine thing it would be crazy. An probly send me like 10 codes or more. Im hoping maybe someone has had this problem an has fixed it. Im startin to lean tord my pessure sensor or afm. I have 720 on there with a hks fcon the older one. I unplugged the fcon an ran stock ecu still did the same thing. Im really confused an it buggin the crap out me cause i have to do emission asap. To day i drove it an it seems like its getting worse an its just sluggish as crap so im think its a sensor that just went out or is on its way.
