I have a 92 grand prix se with a (3.1 or 3.4) motor, cant remember...
the v6 for that year.
It runs perfect, but driving down the highway, it starts to lose
power.
It wont stall, just kinda loses power, and you can play with the gas
peddal, and rev it back up...
Map sensor? O2? Mass airflow?
Can a sensor be jumped with a resistor? to test it?
