Allright guys i need help.
my car ran fine until i had a over heating problem. so i replaced my thermostat and my catch can set up killed my old maf so i replaced that. and i then replaced the exhuast gasket cause it was leaking.
and now

i got the car running. but it is running uber rich almost like it is in a safety mode. and the car is idling around 900 rpms wich is good but when you give it gas it rev but between 3-5000 it like its stuttering really bad and back firing. i have replaced or fixed everything possible to replace. and i switch between my old tune to my new one and it does exactly the same thing.
timing is set at 15dbtc
but the car wont run with it the tps disconnected for me to really set it correctly

oh and one really strang thing. when the car floods. i disconnect the fuel pump to clear out the fuel then it fires up. and normals once that fuel has burned off it dies. but no it idles at 3000 rpms soild wit hthe fuel pump not connected. then if i press the throttle at all it dies.
but i can plug the fuel pump back in and it will drop back down to 900 rpms. weird huh?
its almost making me think that my injectors are part of the problem. but i have been chasing this problem all over the place. and its gettting old

i know i had the cam timing set. but i wonder if it would have been possible for it to jump a tooth on the intak cam. and that would cause it to siphen gas and alow it to run with the fuel pump disconnected.


any input.?
