tune it up
do the right foot test. those are always first. on stalls.
is commonly caused by a dirty automatic idle speed control valve and
throttle valve but always run a OBD2 fault code as well as the
cleaning procedure. Buy a can of throttle valve cleaner (do not use
carburetor spray cleaner!) from NAPA or Carquest (made by CRC
chemicals) and spray it into the air intake while the engine is
running, use up about 1/2 the can, engine will try to stall hold the
speed up, shut it down and let it soak for 30 minutes, restart and
blow out the remaining fluid, shut it down and disconnect the
negative battery cable for 5 Min's to reset the base idle control. If
the above cleaning doesn't cure your issues you need to have the
computer controlled automatic idle speed control system diagnosed and
repaired by a dealer or electronic engine control repair shop.
Without additional information it will be very hard to diagnose the problem.
1. Is it a manual or automatic transmission? 2. When you say pull do you mean that the engine is stalling out or that the car doesn't want to move forward - as in transmission slipping? 3. Have you noticed the transmission slipping before - especially in reverse? 4. Are the fluid correct?
