RFd15bhatch

i have a jdm d15b with a p28 ecu and my problem is the car runs like crap when u start it up it idles fine for a minute or so and when it warms up the car almost sounds like its missing then i went ahead and took it for a drive and when i took off i noticed that the revs were struggling to get up when i finally let the clutch fully engage the rpms dropped to round 500 and i punched it and they just stayed there even at full throttle then they started to climb very slowly wtf is going on with my car i figured it was timing but i have timed it many times and still the same thing any help would be great

Check for poor connections to the TPS and MAP sensors..

Did you just get the engine? After you check the connections, check your valve clearance and compression check your engine. You may have a serious problem with your head gasket...just a thought though.
