7MGTE motor issue
Just finished 7MGE swap to 7MGTE motor fired up fine,just one issue motor has a miss sounds like bup bup intermittently also at the exhaust tip,motor has 60000mls check torque came it at 75-80lbs boost leaked checked and replaced hose clamps,coil pack good new plugs all firing good,I had two suggestions #1 replace fuel pump- injectors are not getting enough fuel,#2 possible tight exhaust valve seeing that the sound comes from the exhaust also.Anyone knows what can be causing this? dont want to start messing with valves /fuel tank unless i have to. Thanks

so only misses when warm, hmmmm..........so off idle it runs fine (basically above 1000rpm) so when it tries to idle it misses. recheck vac lines or sensor going bad, tps, cps, maf...does it smell like its running rich at all?
