I'm not trying say bad thing to your 3800 engine. I just saying it might be bad because of fire and tranmisson blown but now I know everything. It is over with that. Like I say I would swap to 3800 engine if I have any problem with my 3100 engine. I get some of members trying tell me dump 3100 engine and get 3800 engine.
I got home tonight. My gas guage is now under 3/8. I hope it is really exhaust make my gas mileage improving or guage went bad. I have to wait until it is empty. It might be take forever empty that gas
