Talk the Tech Talk

1. ROUGH IDLE — The engine runs unevenly at idle
and the vehicle may also shake.
2. SLUGGISH — With this condition, the engine
delivers limited power under load or at high
speed; it won’t accelerate as fast as normal; it
loses too much speed going up hills and may
have less speed than normal.
3. SPONGY — The engine has less-than-anticipated
response to increased throttle opening (stepping
on the gas); there is little or no increase in speed
when the accelerator is pushed, although continuing
to push the pedal down will finally give an increase
in speed.
4. STALL — The engine stops running or dies. This may
occur at idle or while driving.
5. SURGE — The vehicle speeds up and slows down
with no change on the accelerator pedal.
