So when car is cold everything is fine, but once warms up a bit, wont idle just stalls unless pedal it. When driving and come into neutral as soon as get under 10mph or stop it stalls again.

Brought back to tuner today because had idle issue 2 years ago when first was done, broke valve spring car sat and just got it back together so brought it back.

Upon looking further the drivers side fuel trim is adding 30% while passenger is taking away 8%. When loaded or WOT it evens/ levels out.

What could cause this? injector(s)? being it sat I can see an injector plugging up, but it also had hard time when everything was new and fresh 2 years ago.

The passenger side #4 exhaust spring broke which is on the - 8% side so I dont think its that.

When sitting and idleing almost feels like running on 7 cyl, but again when get into it runs smooth and pulls like a train into boost and everything feels fine.

its a 300ci stroked 9.98:1 CR crower stage 3 cam, Frpp 80#, twin 61mm, e85, solid motor mounts 3" exhaust.

So now the solid mounts and turbo piping and 3" exhaust is close to everything which could make it feel like its missing.

need suggestions..
