some places that sell aftermarket will do a bench flow-test. . .
not sure if they do it for oem's, but if not any place like that should do, and it's fairly cheap iirc.
my 92 sc400 idles real rough, and runs rough while driving at low rpms. Once I get to about 3000 rpm. it smoothes out and runs great. When the car is stopped, it almost will stall. If I accellerate hard, the engine really sounds like it is baffled and barely has power. Wondering if our problems are caused by the same thing.
Problem fixed. Ends up that a coil was intermittent under load. Took a master mechanic 3 hours to diagnose and replace a coil. Two other mechanics had given up on it. Thanks to all you who gave me suggestions! I now have a used MAF for sale that I bought from a member, thinking that was the problem originally.
rough idle fixed
