Question about 1999 Chevrolet Tahoe

Open Question

1999 Tahoe Surges under half throttle load

No engine light. Somewhat of a bucking sensation with RPM sitting at 3k under acceleration. Off idle power is fine. Park rev of engine seems powerful and issue free. Tests I can do to ensure it's transmission failure?

IN your distributer under the rotor is a magnet and a pickup coil (the magnet is known as a pole piece) check your pickup coil for corrsion (green in color) and the module and also check pole piece for cracks in the magnet where the rivets hold it together. sometimes oil wicks up around the distributer shaft because of housing wear or the pieces just wear out over time.

Check your fuel vapor recovery system, your van has unusual set up, and the effect is RAW fuel gets purged, rather than vapor.
The dead giveaway test is does the issue happen on light acceleration? Does it stop if you let off the throttle? Can you accelerate harder and "get past" the issue?

You could have a bad or contaminated Mass Air Flow (MAF) sensor. You can get a used one online for less then 100. You can also purchase a can of MAF sensor cleaner at a local auto supplies store and clean it. It located right at the air filter housing.

Engine surges at rpm over 1500


Look for a vacuum leak (lines and intake), Is the engine light on, were any codes present? A faulty EGR or IAC could cause the problem too. Check the throttle cable for any restrictions.

Clean the IAC. Disconnect throttle body air hose and you will see a hole on the bottom of the throttle body just before the butterfly valve. Spray throttle body cleaner down the IAC hole and then let it soak about 1/2 hour. Reconnect hose and run engine about a minute and then repeat this process 2 or more times. Toyota engines from 1997-2005 commonly have the IAC get cruded up with carbon as early as 35,000 miles. This is a sImple and cheap repair that many repair shops don't want you to know.
