Q: It's a 3.8 engine, which runs well when cold. It has a

The injectors ohm within specs. Tested all coil packs, and
they are ok. I have a bench control module, no change.
Fuel pump pressure is 34 PSI.
Unplug the pressure reg, and the pressure increases to 45.

of the exhaust? Thanks in advance, Bob
PS. One local mechanic told me to just drive it
into the ground. I am retired and this is my
A: This would mean that you are burning about a quart every 10 miles....... the engine would not run without fouling the spark plugs badly...
The only thing I can think of.... this is a turbo engine with a bad oil seal in the turbo.... Ed
